Changing MouseHoverTime affects other areas of the OS as well. A better way is to increase the time in: HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced ExtendedUIHoverTime But both solutions still don't remove the thumbnails in all cases. For example, dragging/rearranging a taskbar item and then clicking it after dropping will make that thumbnail show back up until you move the mouse away. Sad that MS removed the ability to disable them altogether.
Its working totally fine with me no problems with registry or with other areas of the OS There is no ExtendedUIHoverTime in HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
I wasn't a fan of it at first, but as I used Windows 7 more and more, I found it a time saver.. Use the preview to quickly identify which of the stacked windows you want to bring to the front.
I'm not a fan of anything that changes that is why I still have Windows 3.1 installed on this laptop, and use it for my primary OS. Why would you want to use something new when you can continue to use s**t that is outdated and doesn't work well.
If your being sarcastic, I believe the user should be able to determine which features they want to use and which they want to disable. Being forced to use something isnt very nice. And if your serious, then damn too bad for you windows 3.11 sucks a$$, you should upgrade soon.
