Fix: PresentationFontCache.exe High CPU or MEMORY Usage
If you are experiencing high CPU or MEMORY usage on your computer, caused by a process called PresentationFontCache.exe, do not panic. This is a common issue that can easily be fixed.

Firstly, let’s understand what PresentationFontCache.exe is. It is a legitimate system process that is responsible for caching fonts used by applications and the operating system. This helps to improve the performance of these applications by reducing the time it takes to load the fonts.

So, why is it causing high CPU or MEMORY usage? There are a few reasons that could be causing this issue:

1. Corrupted Font Cache: If the font cache is corrupted, it can cause PresentationFontCache.exe to use high CPU or MEMORY. This can happen due to system crashes or improper shutdowns.

2. Large Number of Fonts: If you have a large number of fonts installed on your computer, it can also cause high CPU or MEMORY usage. PresentationFontCache.exe will try to cache all these fonts, which can overwhelm the system.

3. Software Conflict: Sometimes, other applications can conflict with PresentationFontCache.exe and cause it to use high CPU or MEMORY. This usually happens with software that tries to manage or optimize system processes.

Now that we know the possible causes, let’s see how we can fix this issue:

1. Clear Font Cache: The first step is to clear the font cache. To do this, open the Run dialog by pressing Windows + R, type in “services.msc” and press Enter. This will open the Services window. Scroll down and find “Windows Presentation Foundation Font Cache” and right-click on it. Select “Stop” and then navigate to C:\Windows\ServiceProfiles\LocalService\AppData\Local and delete the “FontCache” folder. Once done, go back to the Services window and start the service again. This will recreate the font cache and might fix the issue.

2. Remove Unnecessary Fonts: If you have a large number of fonts installed, consider removing the ones you don’t use. This will help reduce the load on PresentationFontCache.exe. Open the Control Panel, go to “Appearance and Personalization” and click on “Fonts”. Select and remove the fonts you don’t need.

3. Update Graphics Drivers: Outdated or corrupted graphics drivers can also cause high CPU or MEMORY usage. Make sure your graphics drivers are up to date by going to the manufacturer’s website and downloading the latest version.

4. Uninstall Conflicting Software: If you suspect that another software is causing the issue, try uninstalling it. This will help you identify the problematic software and find an alternative.

5. Disable PresentationFontCache.exe: If none of the above solutions work, you can disable PresentationFontCache.exe. This will stop it from running in the background and using resources. Keep in mind that this is not a recommended solution as it can affect the performance of applications that rely on font caching.

To disable PresentationFontCache.exe, follow the same steps as in solution 1 to open the Services window. Right-click on “Windows Presentation Foundation Font Cache” and select “Properties”. Change the “Startup type” to “Disabled” and click on “Apply” and then “OK”. Restart your computer for the changes to take effect.

We hope one of these solutions helped fix the issue. If you are still experiencing high CPU or MEMORY


In conclusion, PresentationFontCache.exe can be a source of high CPU or memory usage for Windows users. However, there are several solutions that can be implemented to fix this issue, such as disabling the font cache service, clearing font cache, or updating font drivers.
