2 Ways to Clear Font Cache in Windows 10

The Windows operating system creates a cache for fonts so that each time you start an application, it loads fonts faster. However, if you have trouble displaying or using fonts, such as fonts appearing garbled, inability to switch fonts, program crashes while switching fonts, etc., then it may indicate that your font cache is corrupted. In this case, you need to clear the font cache, so that Windows operating system will rebuild it to fix any font related problems. Now, on this page, we will show you two ways to clear font cache in Windows 10.

Way 1: Manually clear font cache

Step 1: Stop font cache services.

Open the Services app by typing services in the Cortana search box and pressing Enter.

Locate the Windows Font Cache Service. Double click on this service to open its properties dialog. Click Stop under “Service status” to stop this service, and then select Disabled from the “Startup type” list to completely disable this service. Finally, click Apply.

Navigate to the path C:\Windows\ServiceProfiles\LocalService\AppData\Local. If a warning dialog pops up saying you don’t have permission to access this folder, just click on Continue to allow access. Then delete all .dat files that start with FontCache.

Next, open the FontCache folder. Select all files in this folder by pressing Ctrl + A, and then delete them all. If Windows 10 doesn’t allow you to delete certain files, restart Windows 10 and try again.

After you have deleted all the font cache files, enable both the "Windows Font Cache Service" and the “Windows Presentation Foundation Font Cache” service. Then Windows 10 will rebuild font cache next time when it starts or restarts.

Tips: In general, font cache does not take up a lot of disk space and has no negative effect on the Windows system, so it is not necessary to clear it frequently. Deleting it does not significantly free up hard disk space or improve system performance. Only if you have font displaying problems, you need to delete the font cache to let Windows 10 reset/rebuilt it.
