There are a number of threads in the Microsoft forums where people are reporting issues with these previews and they’re disappearing too quickly and they can’t make a selection. Reboot Windows to make the change take effect.In Windows, the taskbar thumbnail preview allows you to hover your mouse over the application icon and see previews of multiple windows you have open, similar to the screenshot above. In the Value data box, enter the delay desired before the preview pops up, in milliseconds.įor example, entering 60000 makes it so you need to hover on the taskbar for a full minute before the annoying preview window pops up. Paste in the key name: ( ExtendedUIHoverTime) and hit Enter.ĭouble-click the new ExtendedUIHoverTime entry to open it. In the right pane, right-click a blank spot and choose New → DWORD. In the right pane, if ExtendedUIHoverTime already exists, right-click and delete it. Paste into regedit's "address bar" (under the menu bar), then hit Enter:Ĭomputer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced These steps worked for me to effectively disable the taskbar "preview thumbnails" from popping up in Windows 10: It defaults to Hexadecimal which may have unexpected results depending on what value you enter.


Some of the instructions I found online seem to miss the detail of setting the Base type (Hex vs Decimal).
