How to Change Time to Activate Window by Hovering Over with Mouse in Windows

By default in Windows, you need to click/tap on a window to make it active and bring it into focus.

If you turn on Activate a window by hovering over it with the mouse, you can activate a window by hovering over it with the mouse pointer for a half second (500 ms) by default.

If you like, you can change the default time for how long you need to hover over a window before it activates to what you want instead.

This tutorial will show you how to change the default time to activate a window by hovering over it with the mouse pointer for your account in Windows 7, Windows 8, or Windows 10.

Here's How:

1. Press the Win+R keys to open Run, type regedit into Run, and click/tap on OK to open Registry Editor.

2. Navigate to the key below in the left pane of Registry Editor. (see screenshot below)

HKEY_CURRENT_USER\Control Panel\Desktop

3. In the right pane of the Desktop key, double click/tap on the ActiveWndTrkTimeout DWORD to modify it. (see screenshot above)

4. Select (dot) Decimal, type in a number for how many milliseconds (ms) for the time you want, and click/tap on OK. (see screenshot below)

The default time is 500 ms. 1000 ms equals 1 second.

That's it,
