When you hold the WIN-key down when tabbing instead of quickly pressing WIN+`, the windows start menu will pop up, which is terribly annoying. But I managed to get around the issue with a bit of Autohotkey.
; Windows search menu doesn't appear unless you double tab the windows key. WIN+X hotkeys work normally.
; Time is in Milliseconds.
~LWin Up::
If (A_TimeSincePriorHotkey < 300 && A_PriorHotkey = "~LWin Up") {
Click
Send, {LWin}
}
return
