MS made some changes to the Windows registry with Vista and it continues with Win-7.
Registry cleaners, like Easy Cleaner II, have not be re-written for Win-7 and can do more harm than good.
Some people keep touting CCleaner, but the two times I've tried it, it has corrupted my OS so badly that it wouldn't even boot.
Restoring a Ghost Backup was required to get my system back up and running normally.
One NEW program that I've tried on both XP and Win-7 that seems to work well is "AVG Tune Up".
I also used it to optimize my internet connection and it truly worked wonders to speed up my connection.
But when I tried out its Defrag routine, it made such a mess of my HD, that I wound up doing a backup and Restore to put things right again.
Cleaning up a registry and taking out dead links, bad keys, etc., is almost worthless if you don't re-compress the registry after the Clean Up.
The only program that I've found that will do that, SAFELY, is NTREGOPT.
After uninstalling Office 2007 and running Easy Cleaner II, I ran NTREGOPT and it reduced the size of my registry by 1/3.
As for advise to those NON-Tech's, "If in doubt, DON'T!".
Before I ever try out a new program that might mess up my Registry or HD, I do a full C: drive backup.
Good Luck and Happy Holidays mates!
