Prevent Windows from auto deleting thumbnail cache after a restart

How to prevent Win 11 File Explorer from regenerating picture and video thumbnails in any open folder after each reboot? I've Win 11 23H2, and due to changes to File Explorer, this method to stop deleting thumbnail cache at reboot no longer works.

I don't even know where to ask such question, since on official MS Forums the most popular answers to everything are "run sfc /scannow" and "send suggestion to developers" who never listen. On Stack Overflow MS engineers are not frequent, and who else could know about changes in Win Registry?

Also found that Thumbnails option in Windows Settings-System-Storage-Cleanup recommendations-Temporary files doesn't work. No matter whether selected or not, the thumbnail cache is deleted on PC reboot. Then it takes a lot of time after each reboot to regenerate thumbnails in folders with large video collections.
