Windows 10 caches fonts to load them faster. If the font is not displayed properly, the cache may be corrupted.
You will need to clear the font cache in this case, and keep in mind that after the cache is cleared, Windows 10 rebuilds it after you restart.
Let’s look at the steps.
You can now see the Services window.
Search for and select this service: Windows Font Cache Service.
Now stop this service by clicking on its stop button or right-clicking it and choosing the stop option.
The service must also be disabled, and here’s how: Double-click the service. Select Disabled from the drop-down list beside Startup type in the pop-up window. Click OK.
Follow the steps above for this service: Windows Presentation Foundation Font Cache 188.8.131.52.
Open the following folder: C: > Windows > ServiceProfiles > LocalService.
Press the Continue button in the pop-up.
Open AppData. Hit Continue.
Open Local. Hit Continue.
Delete all .dat files that start with FontCache.
Open the FontCache folder and delete everything within it. If deletion fails, restart your PC and try again.
Go to C: > Windows and open the System32 folder. Search for and delete the FNTCACHE.dat file.
Enable and start the services you have stopped earlier.
Restart your PC.
