How to remove the delay for task bar peek in Windows 7 & Windows 10

remove_peek_delay.md

I frequently like to close programs by hovering over a group of windows, and middle clicking them closed.

The problem is, it takes something like a full second before the peek is shown, making the windows uncloseable for that time.

To remove this delay, add/edit the following registry DWORD (32-bit) value:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\ExtendedUIHoverTime

To remove the delay, set it to 1, not 0 (which seems to set it to the default of something like 1000 milliseconds).
