Old_Style After cleaning you can shrink your registry files by entering: scanreg /fix in the last line of autoexec.bat. Restart your computer and it will cleanup your registry, when finished it tells you to restart again, than you have to remove this entry or simply add the "rem" command before it, so it looks like this: rem scanreg /fix whats this do lol any playing around with the registry isnt a good thing! it may look like windows works fine but later on you may find that centein programs or windows programs need them and you wont know why its stuffs up becasue this be a long time after
