XPKeepPerUserDisplaySettings

The Microsoft Windows XP development team has decided that all users sharing a Windows XP PC must have the same display settings -- same resolution, same color depth, same refresh rate.

This is especially annoying in home environments, where mom and dad typically do "serious things" that require higher screen resolutions, like balancing bank accounts, and kids are running games or multimedia apps that often assume 800x600 or 640x480.

If you add to the equation the very nice "Fast User Switching" feature, you end up with the kids' games being displayed in a very small area on the screen or the data in dad's spreadsheet being displayed with only 10 rows!

After some investigation of the Windows XP new APIs, I decided to bite the bullet and try and work around that "design choice" (read: limitation).

Here's the current outcome: a rather small applet (though I've coded it using MFC to be "quicker to market," it doesn't need to be; if there's enough justification I might rewrite it in "plain SDK" code) that you need to run in each user's account, that will save the display settings independently for each user, and restore it at logon AND when switching among several active users.

What does it do?

The program is launched for each and every user -- don't worry, it's rather small -- and monitors the following events:

Each time such an event occurs the current user's display settings are saved in that user's part of the registry.

Conversely, each time a user logs in or becomes active, his/her saved settings are restored.

How to install?

The program is distributed as a SETUP.EXE. Simply "run" the file by double-clicking on it in Windows Explorer. The current version is 1.1.0.65.

Once installation is complete, you do not need to reboot, just log off all active users and log back in, so that the program will be started.

How to uninstall?

First kill all instances of XPKeepPerUserDisplaySettings.exe using task manager (make sure you "show processes for all users"), then run the uninstall from the program's group.

Known problems/limitations

What if it doesn't work?

Special Thanks

To the testers of early versions of the program, especially to Helen, Glenn and Loïc, who spent quite some time providing me with much needed feedback on what was going wrong.
