Windows 7: Limit thumbnail generation to pictures only?

Limit thumbnail generation to pictures only?

Hi.. i like many others have the problem of all thumbnails being spontaneously deleted every other day or so , and all the 250mb worth of thumbnails being slowly generated again only to be deleted..which is a major inconvenience since my processor is comparatively slow and videos take time for thumbnails to be generated.

i found that the deny permission for the explorer folder where the thumbnails are stored does indeed work, however i noticed that while i have this workaround enabled, windows aero starts lagging (the scrolling of explorer pages, even firefox pages, and any graphical effects start occurring in short jerky steps) which i again hate. as soon as i removed those deny permissions (and the thumbnails spontaneously deleted) i haven't encountered that aero lag...so its not my graphics card or driver.

i have currently disabled all thumbnail generation, folder browsing is behaving very fast but it just doesn't look good for pictures...for the videos its livable with.

so any way i could limit thumbnail generation to pictures files only? i have searched around and haven't found anything on this.

thanks.

I think I'd want to know why they are being deleted in the first place?

well the workaround is also listed here in one of the tutorials, the one i had applied Thumbnail Cache - Prevent Windows from Deleting

seems to be a bug in windows 7 which still hasn't been fixed even after sp1. makes me wanna downgrade to vista

Well I'm not having that problem on my system, not that I know of anyway? Are you running any programs that claim to speed up your system, or free up hard drive space etc?

no such programs...got just a few general use apps installed. no reg cleaners or optimizers of any kind.

Discovered something rather interesting;
i had applied the theme patcher which patches 3 system files to apply 3rd party themes previously when i had tried out a theme,
the 'thumbcachetodelete' folder had been created in the appdata/local/microsoft/windows/explorer folder as usual after which the thumbnail cache usually soon disappeared till i applied the workaround listed on this site here Thumbnail Cache - Prevent Windows from Deleting
that folder was still present

i just undid the patching, removed the deny entries for the explorer folder (again talkin bout the workaround) restarted a few times, and that thumbcachetodelete folder is gone without my thumbnail cache disappearing! seems the patching was the problem. the cache is stable now, and the aero lag/choppiness is also not showing up.

OK, I'm glad you got it sorted. Patching/modifying system files always seems to lead to trouble. I can see where people would like to customize Windows, it just seems to backfire more often that not.
