"Action: These allow you to end tasks faster, shut down faster and speed up the menu display. *All Levels
Purpose: Performance, responsiveness
More Info: ForegroundLockTimeout, HungAppTimeout, MenuShowDelay, WaitToKillAppTimeout, WaitToKillServiceTimeout
*note - I have changed the "MenuShowDelay" from 0 to 200. 0 was simply too fast for some people (my wife gave me some grief about it too ). You can edit this as you see fit. The default is 400.
These next 2 tweaks I consider to be optional. One could argue about whether or not they actually have any speed advantage and you may or may not like the result. I strongly recommend you do these two entries manually so that you can easily undo them if you do not like them but you can also copy and paste them into the .reg file.
Action: Disable User Tracking Levels 3 & 4 only
Purpose: Free system resources.
"A value of 1 prevents the system from tracking the programs users run, the paths they navigate, and the documents they open. The system uses this information to customize Windows features. As a result, the system disables customized menus and other features that require user tracking information." (from this page)
is it not that one?
