i got a Dell, originally came with ME installed, and an XP update….. my computer is beyond repair software wise,,, i need to complettly uninstall windows X, and reload the ME, i got all the disks, but i need to know how to start the unistallation process for XP

I am no expert please explain in simpleton terms

I’ve tried several registry cleaners that have scanned my Windows XP but didn’t fix more errors than 15. The last time my computer was scanned, over 600 problems were found in my computer’s registry. Does anyone know of a registry cleaner that is completely free and can fix all the registry problems without buying the un-free version?

wat is this and is it safe
and wat is the best software out there
