I did this reg tweak which has always worked before, but now I still see taskbar thumbnails


Code:
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"ExtendedUIHoverTime"=dword:0001d8a8

Any ideas?

Would you kindly do a screenshot [Snipping Tool] of that situation? My Taskbars only show the icons for programs' executables I've pinned to it.

Please check the video, it used to always show the icon only when I hove over any open window, now it's showing the preview, as if the tweak is not working

Didn't see a video but this statement on the linked page did show up:
The setting in this tutorial no longer works starting with at least Windows 11 version 24H2.
