After Creators Update 2 thumbnails cache keeps auto-deleting

To do that, run Regedit.exe and browse the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Thumbnail Cache

Modify Autoruns DWORD and set its value to 0 and reboot your computer.

YES. Thank you. Tried so many things and this finally fixed it. I've submitted feedback using the feedback hub on this, referencing this solution and hopefully MS will get this resolved for the next update.

Mines not fixed with that reg hack. Something else is up, but it definitely still relates to the thumbnail cache.

Now Automatic Maintenance should no longer delete your thumbnails.

I applied this change 2 days ago and I have no problem since.

Let me know it worked for you, otherwise I'll try to find another fix.

I hope this will help you.

I should look like then. . . correct ?

Yup.

Does anything look wrong with these cache files, that anyone can see?

Have you reset the thumbnail cache size? Is it jjust that Win10 update has reset the cache size to minimum?

Yep did that yesterday, trying that PCworld link next, bar doing a full reset i'm out of ideas. But i'm trying to avoid that, as;

1. I might be left reinstalling all my apps and settings and still have the issue afterwards.
2. I can't really be arsed.

What do you have in mind? I already use Lightroom to look at my RAW files, but I then export them as TIFF files to another folder. When I want to view images in that folder, how do I use something other than File Explorer? Even if I open the image in Photoshop, a File Explorer window opens for navigation purposes.

Thanks, bIOforger. . .

I think i might have found and fixed my Explorer issues (not that anyone cares :) ) i believe it was an issue or something to do with the security/permissions in particular folders on particular drives, which was stopping win from updating the thumbnail cache correctly.

On the harddisc where i have most of my media stored, it had some old SID's for users that don't exist anymore listed for different dirs in the security permissions, as the drive was originally a boot drive in a couple of other PC's ages ago. Since then it became a data drive. Anyway i removed the old SID's and reset the perms to what i would expect them to be at the root level of the drive. At first this made no difference at all to my issues, which i guess makes sense.

So i thought ok lets copy all the data in one of the "problematic folder(s)" into a new folder, delete that folder to rule out any permission issues and see if the thumbnails get created and refreshed correctly.

After moving all the data to a new folder i couldn't open or delete the original folder which had the old SID's in the permissions, even though they had already been removed! wtf. (Access denied) Takeown and Icacls resulted in access denied too, nothing would give me access to the original folder.

So booted into safemode and only then was i able to delete the problematic folder(s).

Then i started to rebuild the thumbnail cache for the "new" media folders and so far, fingers crossed, I've had no more explorer crashes.

As mentioned in my previous posts i had no issues at all in 1703 with explorer, so something very funky has happened in the upgrade process imo.
