The font cache is a file or set of files used by Windows to manage and display the fonts installed on your PC so they load faster.
Sometimes the font cache may become corrupted and cause fonts to be garbled, not rendering properly, or displaying invalid characters. To fix the font cache corruption, you will need to delete the old font cache and restart the computer afterwards to rebuild a new font cache.

Windows keeps a copy of all your picture, video, and document thumbnails in a cache so they can be reused to quickly display when you open a folder instead of having to manually scan and slowly load them each time.

The display cache in Windows 10 helps the computer to remember what mode and resolution to use when a particular display output is detected from a connected external monitor. This helps avoid having to manually apply all the settings again each time a specific external monitor is connected.
Sometimes the cache may have issues, and you find that the display output is not working properly when you connect to an external monitor.
If this happens, you can reset and clear the display cache to see if that fixes the issue. When you reset and clear the display cache, it will force Windows 10 to forget any connected external monitors and their individual settings stored in the display cache on the computer. The next time you connect to an external display, it will be treated as a newly connected display using the default and optimal settings again.
