Stop Windows 10 from Automatic Deleting Thumbnail Cache: When you open a folder containing media files like jpeg image file then you are able to see a small preview of that file in the Windows Explorer. This is made possible in Windows by generating the thumbnail images which is then cached and stored in the database in the user profile directory. The main reason to store the cached file in the database is so the system doesn’t need to regenerate the small preview (thumbnail) of the image or the file everytime you open the folder.
The thumbnail cache (as well as the icon cache) are stored in the following folder:
Note: Replace Your_Username with the actual username of the account.
Now the problem is that Windows seems to automatically delete the thumbnail cache file after every restart or shut down which creates a problem for users. When you open a folder containing hundreds of files then it will take a lot of time to generate thumbnails as the previous thumbnail cache file may have been deleted on system shut down. The main problem seems to be caused by Automatic Maintenance where a task called SilentCleanup is causing the thumbnails to be deleted on every boot.
It is also possible that the issue can be caused by other reasons such as Corrupt thumbnail cache folder, Disk Cleanup utility etc. Also, some 3rd party app can delete thumbnail cache files on every boot, so without wasting any time let’s see How to Stop Windows 10 from Automatic Deleting Thumbnail Cache with the help of the below-listed tutorial.
Stop Windows 10 from Automatic Deleting Thumbnail Cache
Make sure to create a restore point just in case something goes wrong.
Method 1: Prevent Windows 10 from Automatic Deleting Thumbnail Cache
1.Press Windows Key + R then type regedit and hit Enter to open Registry Editor.
2.Navigate to the following registry key:
3.Now select Thumbnail Cache then in the right window double-click on Autorun.
Note: If you can’t find the Autorun DWORD then right-click on Thumbnail Cache select New > DWORD (32-bit) value and name this DWORD as Autorun. Even if you’re on a 64-bit system, you need to still create a 32-bit DWORD.
4.If the value of Autorun DWORD is set to 1 then it means the SilentCleanup feature is enabled which automatically deletes the thumbnail cache on every boot.
5.In order to fix this issue simply double-click on Autorun and change it’s value to 0 then click OK.
6.Similarly, navigate the following registry key:
7.Double-click on Autorun DWORD and change its value to 0 then click OK.
Note: If you can’t find the Autorun DWORD, simply create on as you did in step 3.
8.Close Registry Editor then reboot your PC.
9.You can still clear thumbnail cache by using Disk Cleanup manually.
Method 2: Disable the SilentCleanup Task in Task Scheduler

2.Navigate to the following location:
Task Scheduler > Task Scheduler Library > Microsoft > Windows > DiskCleanup

4.Close everything and reboot your PC to save changes.

1.Go to This PC or My PC and right click on the C: drive to select Properties.
3.Now from the Properties window click on Disk Cleanup under capacity.
4.It will take some time in order to calculate how much space Disk Cleanup will be able to free.
5.Wait until Disk Cleanup analyzes the drive and provides you with a list of all the files that can be removed.
6.Check mark Thumbnails from the list and click Clean up system files in the bottom under Description.
7.Wait for Disk Cleanup to complete and see if you are able to Reset Thumbnail Cache Folder.
