If you are still facing the same issue, you can try tweaking the registry settings.

 

 

 

Method 2: By Manually Recreating Font Cache

 

It’s a possibility that the font cache of your Windows 10 system has gone corrupt. This is when you would see distorted fonts or some other kinds of fonts altogether.

The default location for the font cache file is:

 

C:\Windows\ServiceProfiles\LocalService\AppData\Local\FontCache

 

However, you will not be able to access it directly since it’s a protected folder. Therefore, you can try rebuilding the font cache in Windows 10 manually.

 

*Note – Before you proceed with the method, it’s recommended to create a fresh system restore point, so that, in case if anything goes wrong, you can revert to the previous state.

Even the SFC scan takes a while, so wait patiently. Once the process is over, any corrupt files found are fixed automatically by these two commands.

 

However, if none of the above methods work, the only option left is to either perform a clean install or a repair install. While the Clean install process will help you reset all OS files without using an external storage device as an installation media (make sure to backup all your OS data), Repair install will need an installation media. It will also help you keep your OS data.

Here’s how to create a Windows Installation media for Repair install.
