Over time, the Windows Registry accumulates dead and unused class keys, installtion keys, and other cruft which can gradually slow down the operation of your PC. If you notice the Start Menu taking longer to appear, and Explorer appears sluggish when opening files, it may be time to give the Registry a clean.
I’ve been looking for a good Registry cleaner for a while, and I finally found one: EasyCleaner.
Not only is it free, it also does a nice job of finding dead shortcuts, temporary files that are no longer used, abnormally large files, and plenty more. Particularly useful is the ability to find all large files and directories on a particular partition, to give you a heads up on where all your disk space has gone.
