Way 3. Stop Cleaning up the Thumbnail Cache

Regularly clearing the cache will help improve computer performance and reduce storage space usage. However, clearing the thumbnail cache will cause File Explorer to reload cached files every time, causing slow thumbnail loading issues. So, you can stop Windows from deleting the thumbnail cache by editing Windows registries.

Note:

The Windows Registry contains all the settings and configurations required for the Windows system to function properly. Incorrect deletion or registry values may cause the system to become unbootable. Therefore, we strongly recommend that you back up the registry or the entire system in advance. Regarding system backup, you can use MiniTool ShadowMaker. It provides you with a 30-day free trial.
