presentation font cache what is

Fix: PresentationFontCache.exe High CPU or MEMORY Usage

If your pc got really slow and you checked the Task Manager to see the process that might be using a lot of CPU, you might have seen the PresentationFontCache.exe process in that list. This process might be using 50% CPU or even 100% CPU (in some cases). The high CPU usage will keep your computer running at a slow speed which might disturb your work routine. Even if you end the process from the task manager, it will most probably come back either after a while or once you reboot the system. In some cases, the PresentationFontCache.exe might create problems in the startup and slow down your startup time significantly as well.

The PresentationFontCache.exe is associated with the .Net Framework. The main purpose of the Presentation Font Cache is to load the font glyphs in the memory so that all the WPF (Windows Presentation Foundation) applications can use these fonts. So, whenever you use a Windows Presentation Foundation application, the PresentationFontCache.exe is initiated so that the font’s information is available for the WPF app. Now, to answer why the Presentation Font Cache is using a lot of resources, it has something to do with the corrupt font in the cache. After some time, the font’s information in the memory might get corrupted or unresponsive. This sometimes leads Presentation Font Cache to misbehave and stuck in a restart loop. So, all of this starts using a lot of CPU which creates a lot of problems.

Luckily, there are a couple of solutions for this problem. Go through each of the methods given below and apply the one that is suitable for you.

Method 1: Delete Font*.dat file

Locating and deleting the Font*.dat file seems to work for the majority of users. Basically, a .dat file contains information referenced to an application(s). This file might have been corrupted and causing the issue. So, deleting this file and rebooting will usually resolve the issue for you.

Here are the steps for deleting this file

• Hold Windows key and press R
• Type C:\Windows\ServiceProfiles\LocalService\AppData\Local\ and press Enter

• Locate a file named Font*.dat (or FontCache 3.0.0.0.dat )
• Right click Font*.dat (or FontCache 3.0.0.0.dat ) and select Confirm any additional prompts

• Once done, reboot .

Note: If you can’t access the folder then do the following. Hold Windows key and press R . Type control panel and press Enter . Select Appearance and Personalization . Select File Explorer Options (or Folder Options). Click the View tab. Select the option Show hidden files, folders, and drives in Advanced Settings section. Click Apply then select Ok . Now perform the steps given above. If you still can’t access the location then you will have to navigate to this location manually.

Everything should be fine after the computer is restarted.

Note: If you can’t delete the file then stop the PresenetationFontCache.exe from the Task Manager. Press CTRL, SHIFT and Esc (CTRL + SHIFT + Esc) simultaneously. This will open up the Task Manager. Now, select the PresentationFontCache.exe from the list and click End Task. Now perform the steps given above.

Method 2: Stop Presentation Font Cache Service

As mentioned in the beginning, PresentationFontCache.exe is used with the Windows Presentation Foundation applications. It will most likely be initiated once a WPF application starts running. So, if you don’t use any WPF applications then disabling the Presentation Font Cache service will resolve the issue for you. If you aren’t sure, WPF applications are the ones created in Visual Studio for Windows Desktop. So, if you aren’t using any of these applications or you aren’t a developer then you should be fine after disabling the Presentation Font Cache service.

Here are the steps for disabling the Presentation Font Cache service

• Type services.msc and press Enter

• Locate a service named Windows Presentation Foundation Font Cache 3.0.0.0 and double click it

• Select Disabled from the drop down menu in Startup Type section

• Click Stop if the Service Status is Running
• Click Apply and select Ok

Once done, you should be good to go. The service shouldn’t start anymore and your CPU usage should go down.

Method 3: Repair .Net Framework

If the above two methods didn’t work then your last resort is to repair the .Net Framework. Since the Presentation Font Cache is associated with the .Net Framework, repairing and problems in the Framework will usually fix the issues with Presentation Font Cache as well.

• Type appwiz.cpl and press Enter

• Locate Microsoft .Net Framework 3.0 (you might have another version). Select this entry and click Change/Remove
• A new window should open. Select Repair and follow any additional on-screen instructions
• Repeat these steps for all the instances from the list (you might have multiple instances)

Once done, you should be good to go.

What is PresentationFontCache.exe and Why is it Running?

If you’re browsing the running tasks on your Windows PC, you may notice a file called PresentationFontCache.exe and wonder why it’s running. We’ll explain what it does and how to make sure it’s malware-free.

If you’re looking at  Task Manager on a Windows computer, you might see  PresentationFontCache.exe running in the background. You might assume it has something to do with fonts. Is it a valid file? Could it be part of malware or a virus ? Great questions. Let’s review what PresentationFontCache.exe is and why it is running. We’ll also discuss whether you should be concerned.

What is PresentationFontCache.exe?

PresentationFontCache.exe is a helper for your computer when you use certain apps. The file is part the .NET Framework. What it does is load information about your computer’s fonts (the way letters and characters look). This way, when you use specific types of apps (like those made with Windows Presentation Foundation), everything works smoothly.

In simple terms, PresentationFontCache.exe is there to make sure fonts look good in certain apps you might use. The fonts in the cache can become corrupted, though. This might cause such apps to use a lot of CPU power. Often, you can fix this by restarting the associated service mentioned further below.

Normally, you find this file in C:\Windows\Microsoft.NET\Framework64\v3.0\WPF . This folder can be different. It all depends on which version of Windows you are running.

It also has a related Windows Service running. Depending on the version of the PresentationFontCache.exe file, the service could have another name. However, it will be similar to  Windows Presentation Foundation Font Cache 3.0.0.0.

Is This File Safe?

The file is typically safe. After all, it is part of the Microsoft .NET Framework. Still, it’s crucial to be aware of potential security and performance concerns:

• Malware Impersonation:   Malicious software can disguise itself using filenames that resemble legitimate system processes. This includes PresentationFontCache.exe. Always ensure that the process is located in the C:\Windows\Microsoft.NET\Framework64\v3.0\WPF directory. Later versions might change to 3.1 or 4.0 and so on. You should also make sure it’s digitally signed by Microsoft.
• Resource Usage: In some instances, you might notice PresentationFontCache.exe consuming a significant amount of system resources like CPU. Such behavior might suggest that some fonts in the cache are corrupted and require deletion. As mentioned earlier, a restart of the service Windows Presentation Foundation Font Cache 3.0.0.0 usually fixes it. If that doesn’t fix the high CPU usage you might have to delete a font cache file under C:\Windows\ServiceProfiles\LocalService\AppData\Local named FontCache 3.0.0.0.dat and then reboot the computer.

How to Check if the File is Correctly Digitally Signed?

As mentioned, you may need to verify that PresentationFontCache.exe is located in the C:\Windows\Microsoft.NET\Framework64\v3.0\WPF directory first. Depending on which Windows version you run, you might be able to right-click the file in Explorer and look at the Digital Signature tab.

However, that option isn’t always visible in later versions of Windows 11. The following method, using PowerShell, works on all Windows versions. No worries, it is a one-liner that you can easily copy and paste to run.

• Open  PowerShell  (no need to open it elevated)

Get-AuthenticodeSignature -FilePath C:\Windows\Microsoft.NET\Framework64\v3.0\WPF\PresentationFontCache.exe | Format-List

• Issuer: CN=Microsoft Windows Production PCA 2011, O=Microsoft Corporation, L=Redmond, S=Washington, C=US
• Status: Valid
• If the issuer is the above, that indicates Microsoft issued the signing certificate. Next, the Status should read as valid. Those parameters together ensure that you can trust this file.

Don’t Worry, PresentationFontCache.exe Is Usually Perfectly Legit

As discussed, PresentationFontCache.exe is normally a valid Microsoft Windows file. To be safe, just verify the file has the correct digital signature. Also, be sure it runs from the correct folder matching the path to the related Windows Service.

Windows Presentation Foundation Font Cache 3.0.0.0 Process Explained

Written by: Stelian Pilici

Published on: June 30, 2023

When you open the Task Manager on your Windows computer, you may notice a process called “Windows Presentation Foundation Font Cache 3.0.0.0” running in the background. This process, also known as “PresentationFontCache.exe,” is a legitimate component of the Windows operating system. In this article, we will explore why this process is running, its purpose, and whether it is necessary for your system’s performance.

This Article Contains:

What is Windows Presentation Foundation (WPF)?

Before diving into the Font Cache process, it is essential to understand what Windows Presentation Foundation (WPF) is. WPF is a graphical subsystem in Windows that provides developers with a unified programming model for building rich, interactive user interfaces, including desktop applications, web applications, and games.

WPF uses XAML (eXtensible Application Markup Language) to define the user interface elements, such as buttons, text boxes, and images. It also supports advanced features like animation, data binding, and multimedia integration.

The Purpose of the Font Cache Process

The Windows Presentation Foundation Font Cache 3.0.0.0 process is responsible for caching font data used by WPF applications. When you launch a WPF application, it needs to load and render various fonts to display text correctly. However, loading fonts can be a time-consuming process, especially if there are many fonts installed on your system.

To improve performance, WPF caches font data in memory, allowing subsequent launches of WPF applications to load fonts more quickly. The Font Cache process continuously runs in the background, monitoring changes to the installed fonts and updating the cache accordingly.

Is the Font Cache Process Necessary?

Yes, the Font Cache process is necessary for the proper functioning of WPF applications. Without the font cache, every time you launch a WPF application, it would need to load and process font data, resulting in slower startup times and potential performance issues.

By preloading and caching font data, the Font Cache process significantly improves the performance of WPF applications, ensuring a smooth and responsive user experience. It also reduces the strain on system resources, as fonts do not need to be loaded from disk every time they are used.

Common Issues and Troubleshooting

While the Font Cache process is generally beneficial, there are instances where it may cause problems. Here are some common issues associated with the Font Cache process and possible troubleshooting steps:

1. High CPU or Disk Usage

In some cases, the Font Cache process may consume a significant amount of CPU or disk resources, leading to performance issues. If you notice unusually high CPU or disk usage by the process, you can try the following steps:

• Restart your computer: Sometimes, a simple restart can resolve temporary issues with the Font Cache process.
• Open the Start menu and search for “Services.”
• In the Services window, locate the “Windows Presentation Foundation Font Cache 3.0.0.0” service.
• Right-click on the service and select “Stop.”
• Navigate to the following folder: %windir%ServiceProfilesLocalServiceAppDataLocal
• Delete the “FontCache3.0.0.0.dat” file.
• Restart your computer.
• Scan for viruses or malware: Sometimes, malware or viruses can disguise themselves as legitimate processes. It is always a good practice to scan your system with reliable antivirus software like Malwarebytes Free to ensure your system is clean.

2. Font-related Issues in WPF Applications

If you encounter font-related issues in WPF applications, such as incorrect font rendering or missing characters, it could be due to a corrupted font cache. To resolve these issues, you can try the following steps:

• Clear the font cache: Follow the steps mentioned earlier to clear the font cache.
• Reinstall problematic fonts: If the issue persists, you can try reinstalling the fonts causing the problem.
• Repair or reinstall WPF: In extreme cases, you may need to repair or reinstall the Windows Presentation Foundation component to resolve font-related issues.

The Windows Presentation Foundation Font Cache 3.0.0.0 process is an essential component of the Windows operating system, specifically designed to improve the performance of WPF applications. By caching font data, it allows WPF applications to load fonts more quickly, resulting in a smoother user experience.

While the Font Cache process is generally beneficial, it can sometimes cause issues like high CPU or disk usage. In such cases, you can try troubleshooting steps like restarting your computer, clearing the font cache, or scanning for viruses and malware.

Understanding the role of the Font Cache process and knowing how to troubleshoot common issues can help you maintain a stable and efficient Windows system.

Here are 10 basic security tips to help you avoid malware and protect your device:

Use a good antivirus and keep it up-to-date.

It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

Keep software and operating systems up-to-date.

Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

Be careful when installing programs and apps.

Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

Install an ad blocker.

Use a browser-based content blocker, like AdGuard . Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

Be careful what you download.

A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

Be alert for people trying to trick you.

Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

Back up your data.

Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

Choose strong passwords.

Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

Be careful where you click.

Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

Don't use pirated software.

Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.

WPF PresentationFontCache. What is this?

I have .Net 3.5 SP1 with developement done in WPF.

Whenver I run my WPF application I see a process named "PresentationFontCache" appears in my Process List (on Task Manager). The process, though appears harmless, actually resides in the memory even after the WPF application is closed. What is this process actually? What does it do?

So when I try to check the memory usage (by executing and closing the application numerous times) the process gives a feel that some memory is still in use. also I have observed that this process can turn nastily resource hungry (30% CPU usage and/or 100 MB memory usage under certain conditions!!!).

I located the windows service, named "Windows Presentation Foundation Font Cache 3.0.0.0", which is probably responsible for generating this process. This service claims that it optimizes performance of WPF applications by caching commonly used font data. WPF applications will start this service if it is not already running. It can be disabled, though doing so will degrade the performance of WPF applications..

But then why doesnt the windows service itself close the process after the WPF application is closed.

Or is it that this services actually caches the font information used for any WPF apps collectively so that next time any of the similar apps, when rerun, will use the cache without regenrating the fonts for the application? If so isnt that a type of data which cannot be garbage collected? Isnt that a probable cause leading to memory leak?

Please elight me.

• memory-leaks
• presentation

This service is designed to improve the performance of WPF applications and increase the amount of shared resources between WPF programs (or different instances of the same program). The source is available for it as part of the Reference Source Code Center , and some more information on WPF application performance in general can be found here .

There are isolated instances of where this service causes a problem, but for what it's doing I don't think that occasional CPU spikes and 100mb memory usage are problematic.

You can safely disable the service if you believe it is taking up too many resources, but you're better off profiling / measuring what effect that has on your application.

Error message or high CPU utilization when running a WPF-based application

• 4 contributors

This article helps you resolve the problem where you receive a FileFormatException or ArgumentOutOfRangeException error message in a Windows Presentation Foundation (WPF)-based program when the WPF-based program processes text.

Applies to:   Windows Presentation Foundation Original KB number:   937135

When you run a WPF-based application in the Microsoft .NET Framework 3.0, you may receive a FileFormatException error or an ArgumentOutofRangeException error. The error occurs when the WPF-based application starts to process text. For example, you may receive a FileFormatException error message that resembles the following:

file:///filepath/file_name file does not conform to the expected file format specification.

In this error message, file_name is typically the file name for a font. Additionally, the application consumes up to 100 percent CPU time.

When looking in Task Manager or other tools, PresentationFontCache.exe consumes 50% or more of available processor time.

This issue occurs if video drivers overwrite the data in the font cache that is stored in memory.

To resolve this issue, follow these steps:

Exit all WPF-based applications that are running on the computer.

Stop the Windows Presentation Foundation Font Cache 3.0.0.0 service. To stop the Windows Presentation Foundation Font Cache 3.0.0.0 service, use one of the following methods.

Method 1: Use Microsoft Management Console

• Click Start , click Run , type Services.msc , and then click OK .
• Right-click Windows Presentation Foundation Font Cache 3.0.0.0 , and then click Stop .

Method 2: Use the command prompt

• Click Start , click Run , type cmd , and then click OK .
• At the command prompt, type net stop "Windows Presentation Foundation Font Cache 3.0.0.0" , and then press ENTER .

Delete the old Fontcache3.0.0.0.dat file.

By default, the Fontcache3.0.0.0.dat file is located in the %windir%\ServiceProfiles\LocalService\AppData\Local folder in Windows Vista. By default, the Fontcache3.0.0.0.dat file is located in the %systemdrive%\Documents and Settings\LocalService\Local Settings\Application Data folder in Windows XP and in earlier versions of Windows.

Update the video card drivers. To do this, use one of the following methods.

Method 1: Use Windows Update Catalog

To update the video card drivers, check for updates in the Windows Update Catalog. For more information about how to download drivers from the Windows Update Catalog, see How to download updates that include drivers and hotfixes from the Windows Update Catalog .

Method 2: Download and then install the latest video card drivers

To download and install the latest video card drivers, contact the computer or the video hardware manufacturer.

More information

If the video card drivers overwrite the data in the font cache that is stored in memory, the corrupted data may be saved to the hard disk as a data file. Therefore, you may experience the issue that is described in the Symptoms section when another WPF-based application tries to read the corrupted data file.

After you update the video card drivers and after you delete the Fontcache3.0.0.0.dat file, a new font cache data file is created based on the new computer configuration. This new font cache data file is created when the Windows Presentation Foundation Font Cache 3.0.0.0 service is stopped. Typically, the new font cache data file is created when the computer is shut down or restarted.

You are here, how to fix: disable presentationfontcache.exe (high cpu).

Infopackets Reader Teresa P. writes:

" Dear Dennis,

My computer has been acting terribly slow! I pressed CTRL + ALT + DEL to bring up Task Manager to see what was going on, and I have a task called presentationfontcache.exe that is eating 25% of my CPU. This is an older computer, and these days I need all the CPU processing power I can get - and this definitely isn't helping! Can you please tell me how I can disable presentationfontcache.exe in Windows 7? "

My response:

I have not had this problem before so I asked Teresa if she would like me to look at the issue more closely using my remote desktop service . She agreed and allowed me to connect, and sure enough - the task 'presentationfontcache.exe' was eating 25% of her CPU.

From what I've read online, the presentationfontcache.exe file is a service used for caching fonts, related to Windows Presentation Foundation (WPF) applications. I have never seen a WPF application (that I am aware of) in the last 30 years of my computing life - however, a from a bit more research, this service seems to be related to a lot of programming-related activities, including Microsoft Visual Studio. By default any application using WPF framework will enable the Windows Presentation Font Cache service, though it's my understanding this service can safely be disabled.

After a bit more digging online, I came across some instructions that will help fix the presentationfontcache.exe from eating all the CPU, plus other instructions that explained how to disable it entirely. Unfortunately neither of the sites I visited explained how to do this clearly (for the average Joe user); as such, I've decided to completely rewrite the instructions and streamline the process to minimize the amount of steps needed - plus I'll explain how to do it in simple English.

• First, you will need to open up an administrative command prompt. To do so: click Start, then type in "cmd" (no quotes); wait for "CMD.EXE" or "Command Prompt" to appear in the list, then right click it and select "Run as Administrator".  
• The commands below will clear out the Font Cache folder, set the Windows Presentation Foundation service to manual, then restart the service. To do so: highlight the text below using your mouse: c: cd C:\Windows\ServiceProfiles\LocalService\AppData\Local\ mkdir temp move font*.dat temp REG add "HKLM\SYSTEM\CurrentControlSet\services\FontCache3.0.0.0" /v Start /t REG_DWORD /d 3 /f net stop FontCache3.0.0.0 net start FontCache3.0.0.0 echo this is a dummy line  
• Right click over top of the highlighted text above, then select "Copy" from the dialogue menu. Next, go to the administrative command prompt you opened up in Step #1 and then right click in the middle of the window and select "Paste" from the dialogue menu. The text you copied in Step #2 should now be output to the command line.  
• Now, check Task Manager to make sure presentationfontcache.exe isn't eating 25, 50, or 100% of your CPU. To do so, press CTRL + ALT + DEL on the keyboard; Task Manager will appear automatically in Windows 7 and earlier - however, for Windows 8 and 10 users, you will need to click the "Task Manager" link in order to run Task Manager after pressing CTRL + ALT + DEL on the keyboard. Once Task Manager is running, go to the "Processes" tab in Windows 7 and earlier (the "Details" tab in Windows 8 and later), and look to see if you can find the presentationfontcache.exe program and see if the CPU usage is still running rampant. If it is, then proceed to Step #5.  
• ONLY do the following steps if presentationfontcache.exe is still eating your CPU. The following steps will stop the Windows Presentation Foundation service and disable it permanently (though, this can easily be reversed). To do so, use your mouse to highlight the text below: net stop FontCache3.0.0.0 REG add "HKLM\SYSTEM\CurrentControlSet\services\FontCache3.0.0.0" /v Start /t REG_DWORD /d 4 /f echo this is a dummy line  
• Right click over top of the highlighted text above, then select "Copy" from the dialogue menu. Next, go to the administrative command prompt you opened up in Step #1 and then right click in the middle of the window and select "Paste" from the dialogue menu. The text you copied in Step #5 should now be output to the command line.

At this point, you should not see presentationfontcache.exe running in task manager, and your CPU should be running a lot more smoothly. If for some reason the presentationfontcache.exe is still running, do a reboot and that should definitely prevent it from running again.

Note that any program which relies on the Windows Presentation Foundation service may run slower, because the fonts are being cached. If you don't know which program that may be, I would not worry about it too much as the majority of programs I came across were for programming purposes.

I hope that helps!

Similar Problems

I have experienced similar problems with my HP laptop running Win10. I did not have these problems until the 1607 upgrade.

It all started in August with 100% disk usage caused by HPSupportSolutionsFrameworkService.exe. Shutting down the laptop or rebooting did not clear the problem. The service needed to be terminated using Process Explorer.

Later in September, WmUpdate caused svchost to run continuously at 12% CPU useage, As before, Process Explored fixed the problem.

Later in October, MSMPEng.exe ran continuously at 12% CPU useage. Again Process explored did the trick.

Now about every two weeks HPSupportSolutionsFrameworkService.exe acts-up with 25% CPU usage. This time I can double-click / run HP Support Assistant, immediately shut down the program and the problem clears.

I hope the new Win10 upgrade in March will fix this and other nuisance bugs with the USB and Wi-Fi. My other choice is to try a clean install with the latest “save data” option. Do you have any comments about this latest download?

Therefore, when you run a WPF app, the PresentationFontCache.exe will be started in order to offer font’s information for the app.

However, sometimes users may find that the PresentationFontCache.exe process is using a lot of CPU resources (up to 50% or even 100% in some cases). It slows down the computer . Although they end the process in Task Manager , it could appear again after a while or when you restart the PC. PresentationFontCache.exe high CPU might also slow down the startup.

What is "Presentation Font Cache"?

And why is it using 60% of my CPU? :\

I don't want to delete it in case it's important, but when the process has "60" in the CPU column, that worries me. I don't even know what it's doing.

EDIT: Apparently since some of us love to patronise, I will point out that I have tried google, none of the fixes did anything, the program just started up the next time I started my PC. :\ That in itself is worrying, actually.

I looked in "Services", couldn't find it. That seemed to be the most logical fix up until that point. If the service isn't running, why is the process?
