How to Stop and Prevent Windows from Deleting the Thumbnail Cache
Information
This tutorial will show you how to stop and prevent Vista and Windows 7 from deleting and clearing the
thumbnail cache and causing you to not have
thumbnail previews until reloaded again.
This is a good workaround if Windows is randomly deleting and clearing your thumbnail cache.
You must be logged in as an
administrator to be able to do this tutorial.
OPTION ONE
To Prevent Windows from Deleting the Thumbnail Cache
NOTE: This option will only stop and prevent Windows from being able to delete the thumbnail cache. This will not prevent users from being able to manually delete or from using Disk Cleanup to delete their thumbnail cache.
1. In Windows Explorer, navigate to the
hidden system folder below, right click on the
Explorer folder, and click on
Properties. (see screenshot below)
C:\Users\User-Name\AppData\Local\Microsoft\Windows\Explorer
2. Click on the
Security tab, then click on the
Advanced button. (see screenshot below)
3. In the
Permissons tab, select (highlight) the
SYSTEM entry, and click on the
Change Permissions (Windows 7) or
Edit (Vista) button. (see screenshots below)
4. Select (highlight) the
SYSTEM entry, and click on the
Edit button. (see screenshot below)
5. Scroll down a bit, check the
Deny box for both the
Delete subfolders and files and
Delete permissions items, then click on
OK. (see screenshot below)
6. Click on
OK. (see screenshot below step 4)
7. Click on
Yes. (see screenshot below)
8. Click on
OK. (see screenshots below step 3)
9. Click on
OK. (see screenshot below step 2)
Note
If this still doesn't help afterwards, then repeat the steps above for each user and group listed under the Name column (step 3) to prevent everything from being able to delete the thumbnail cache.
OPTION TWO
To Allow Windows to Delete and Clear the Thumbnail Cache
NOTE: This is the default setting. This option is to undo OPTION ONE above.
1. In Windows Explorer, navigate to the
hidden system folder below, right click on the
Explorer folder, and click on
Properties. (see screenshot below)
C:\Users\User-Name\AppData\Local\Microsoft\Windows\Explorer
2. Click on the
Security tab, then click on the
Advanced button. (see screenshot below)
3. In the
Permissons tab, select (highlight) the
SYSTEM entry with
Deny as the type, and click on the
Change Permissions (Windows 7) or
Edit (Vista) button. (see screenshots below)
4. Select (highlight) the
SYSTEM entry with
Deny as the type, and click on the
Remove button. (see screenshot below)
