I have Easy Cleaner 2.0 on my Windows XP PC. Upon running the Registry cleaner, it came up with 220 invalid entries. Is it safe to delete these? Should I somehow backup my system before I delete them?

I have a corrupt registry – have lost use of my printer – get the dreaded "blue" screen or total "whiteout." Some dll errors, etc.I can’t seem to find a truly free deep registry cleaner just the scan. There are some "cleaners’ available, but they only do a very shallow clean. I have windows ME operating system!

I’ve seen a few people on here asking for links for free registry cleaners so I’m posting these links for a complete pc security a/v anti-spy anti hacker firewall and registry cleaner.

Hi to you 750 rider, you are wrong, totally, I run all of these on my own pc, and I advise others to run it as well, it’s very good, I can vouch for that and I am an IT practitioner with long experience, and I know my onions.
Hi Rich, well I never had to do anything like that, this is the configuration I run now, and have done for a while. I stopped running it for a couple of weeks trying out other stuff, and my pc got root kit(which I got rid of with Panda) , and loadsa other c**p so I went back to the above and it runs well. Totally pleased with it.
I use XP and don’t like Vista, maybe that’s why it runs better…..

Were can I find a great registry cleaner and defragmenter. Is there one that is not a trial but 100% free to download.

I’m not sure what a registry cleaner does. I want to run the registry cleaner, but I don’t know if it will erase my documents. Much appreciation for whoever answers this.
