How will you know which registry cleaner will work for you?

Registry is the databse of windows which stores all configuration information. When you install or uninstall something, this information is saved in registry.

Yes, for example computers running with OS Linux or freebsd.

A registry is your computers main function. Without it, your computer wouldn't work. Every time you un-install something, bits and pieces of information are leftover, which could and will eventually...

First of all windows xp registry cleaner scans n finds all those files that r corrupted after that it deletes all corrupted n unnecessary files from our pc.

In Windows go Start -> Run -> Type "Regedit" in the run box (leave out the quotation marks). Note: You can seriously damage you operating system by working with the Resgistry Editor.
