Disabling Taskbar Thumbnails no longer works on 24H2


Hi, I'm on 11 Pro, V 24H2 build 26100.4061. Admins pushed an update this week, everything in my Taskbar is showing Thumbnails now and I CANNOT get them to go back to text-only Previews.

My HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband\NumThumbnails is still at 0...

I tried going into Group Policy and enabling "Turn off taskbar thumbnails".

Also tried creating a DWORD for ExtendedUIHoverTime in
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced and setting to Decimal 60000 as suggested here.

In my work I constantly have a lot of open emails, Excel spreadsheets, Word docs, File Explorer windows... It is SO annoying to have to move the mouse horizontally to access or close huge Thumbnails, as opposed to vertically-scrolling nice succinct text-only Preview lines.

WHY would Microsoft need to force all users to view Thumbnails of their open programs??!?!?!!?

Please tell me a fix is coming (outside of having to install 3rd party program).

I have the exact same situation, including the same build number.

And just to note, the hexadecimal / decimal thing in Regedit is just how the UI works. It doesn't matter which one you use so long as you supply the right value -- "60000" in decimal is equivalent to "ea60" in hex.
