This is for Vista but works fine in Windows 7. Be safe! Backup the Registry and/or make a System Restore point before doing the regedit.
For those of you who love to have your mouse cursor autofocus on the window it’s hovering over with NO delay and being able to click anywhere on a window to bring it to the foreground, this is for you!
Open regedit, go to HKEY_CURRENT_USER\Control Panel\Desktop
Edit UserPreferenceMask value to be 9F 3E 07 80 12 00 00 00
You should only have to modify the first pair.
In the same place in regedit, edit ‘ActiveWndTrkTimeout’, change ‘Base’ to Decimal and put in 0 as the ‘Value Data’
Log off and log back in
Bask in the glory of your instant autofocus that doesn’t bring the window to the foreground, doesnt force you to click on the title bar or frame of a window to bring to front, and most importantly, DOESN’T SUCK or force you to use 3rd party application!!
Hopefully someone else finds this as useful as I did!
