I'm not bright enough to have an original registry tweak; however, here is a "registry tip" I thought up all by myself. After I complete a fresh installation of XP, I export from the registry this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services Then when I've completed setting up services to my liking, I export the same key again ... This way I'll have it ready to setup Services instantly for me the way I like them should I re-install or do a repair install. If I choose to revert back to default settings, I have that too. Actually, it's more of a time-saver tweak I guess. Oh, wait. I have one more: I setup my Security Settings according to this page:http://www.jfitz.com/tips/ie_security_config.html I feel pretty secure with these settings; however, you can't use Windows Update with your Security Settings setup this way. So, before I adjust my settings, I export this key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones. (That's the Default Settings.) After I have them setup, I export that same key again, and name it "Adjusted Settings.reg" Then when I need to get to Windows Update, I click and add the Default Setting reg file. When I'm done updating, I click on my Adjusted Settings reg file. Credit to Dirk Diggler for helping find the registry key I wanted to export.
