I just love it when a group policy doesn't do completely what it claims anymore.
I tried the latest .reg file and it has no impact on Win7 Home Premium 32-bit - cleared out explorer thumbnail cache with Windows Disk Cleanup utility before adding thumbnail-disable registry entries and then rebooted, then cache continues to be rebuilt as directories are browsed. Editing / rotating an image still leaves explorer thumbnails out of sync with image.

I will be going with terry60's approach (thanks for the info!):

Ignore all the subsequent stuff about the cats, turns out that that was just embedded metadata and nothing to do with caching at all.
Setting group policy etc. has no effect whatsoever, so why MS provides such policy settings when they do nothing is a major question.
Turns out, the only way to prevent W7 (and W8) from cluttering your valuable SSD C drive space with unwanted junk in the form of thumbnails, is to navigate down to ...Users/yourname/appdata/local/Microsoft/Windows/Explorer
right click on that folder, select properties> security and remove all access to it.
Leave it so that only you (not the system) have access and remove your own ability to write inside it.
Just leave yourself with ownership and read access.

Make sure you do a disk cleanup first, or what's inside the cache will be stuck there forever wasting space.

I have Win7 Pro SP1 64bit

NEITHER of the Options in post worked, IconCache.db is rebuilt EVERY time I boot

I even verified the Registry entries after using Option One.

I use Local Policy Editor and set to disable icon cache (enable settings in policy).

Something in your post is missing.

Hello tecknomage,

This only disables the thumbnail cache thumbs_*.db database files stored at the hidden system folder below.

C:\Users\User-Name\AppData\Local\Microsoft\Windows\Explorer

Check post #16
That's the only way to kill thumbnail caching in W7/8/8.1/10
The GPE and regedit methods should work in theory, but demonstrably don't do what they claim.
