2/** @file
3 * RegCleanup - Remove "InvalidDisplay" and "NewDisplay" keys on NT4,
4 * run via HKLM/.../Windows/CurrentVersion/RunOnce.
5 *
6 * Delete the "InvalidDisplay" key which causes the display applet to be
7 * started on every boot. For some reason this key isn't removed after
8 * setting the proper resolution and even not when * doing a driver reinstall.
9 * Removing it doesn't seem to do any harm. The key is inserted by windows on
10 * first reboot after installing the VBox video driver using the VirtualBox
11 * utility. It's not inserted when using the Display applet for installation.
12 * There seems to be a subtle problem with the VirtualBox util.
