Q. How can I disable all user's Desktop Cleanup Wizard by adding a line to the logon script?

Using REG.EXE, built into Windows XP, Windows Server 2003, and later operating systems, or installed from the Windows 2000 Support Tools, add the following line to the logon script:

REG ADD HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerDesktopCleanupWiz /V NoRun /T REG_DWORD /F /D 1
