Windows 7: Unable to Disable Thumbnail Cache

Unable to Disable Thumbnail Cache

Hello,

I have followed the guides online for disabling the Thumbnail cache in Windows 7 (Specifically, the .db files generated when pictures are loaded in Windows Explorer)

I disabled it via the tutorial on this website, I have also disabled it in Group Policy Editor... I cleared the existing cache, rebooted, and when i load directories with pictures in them, the .db file(s) are still being generated.

I do not wish to disable the display of thumbnails in Windows Explorer...I realize this is the easiest method of ensuring they are not generated in the .db. However there must be a way to prevent windows from doing so. I am unclear as to why mine wont.

I'm curious why you want to do this as it will slow Windows Explorer down when displaying files that require icons.

I am running a Samsung 840 Pro SSD. My average read is 519Mb/sec. Speed isnt an issue.

Security is the concern. Business security. Opening sensitive files that could be recovered or could be downloaded if the system ever became compromised.

*Facepalm*

Perhaps you missed the part where I said I had followed the tutorials on this site. I ran the reg "hack" that was available (and in the past ive done the manual editing)

No effect. Windows still generates the .db when I open folders containing pictures, and when its configured to display thumbnails

Well slap my face and pull my hair! I often read (or not) too fast.

Read my posts in this tut, I had the same problem. I also used CCleaner to delete the thumbs.db.
I use this Thumbnail Database Viewer - IT Samples to see if they indeed are gone.

This can clean them too. Thumbnail Database Cleaner - IT Samples

As Brink states thumbs are generated but the reg change keeps them from being cached, saved.

Well they are definitely being generated AND saved. Against registry settings and against Group Policies.

Very confused as to why Windows seems to be ignoring the settings and allowing them to persist...If I reboot, the previous thumbnail cache exists as it did before the reboot. So its not even like Windows is storing them for one session only.

Odd behavior that. I can only suggest the two free programs I listed. I find my system still had the db folders but have notin in them. If you haven't tried it, as I say I use CCleaner too. CCleaner - Update Free version from Piriform site.

Is there a method to prevent Windows from writing to a particular directory? Perhaps setting it read-only?

I don't know that one. You can try read-only though.
