Subject to all the warnings above - which cannot be stressed sufficiently - another good Registry Cleaner is RegSeeker from Hover Inc. The Home Site describes the current version 1.45 as below:
"RegSeeker is a perfect companion for your Windows registry !
RegSeeker includes a powerful registry cleaner and can display various informations like your startup entries, several histories (even index.dat files), installed applications and much more ! With RegSeeker you can search for any item inside your registry, export/delete the results, open them in the registry. RegSeeker also includes a tweaks panel to optimize your OS ! Now RegSeeker includes a file tool to search for duplicate files, bad shortcuts and more !
RegSeeker is FREE for personal use only !"
I have tried this on occasions and till date experienced no problems.

Hope this helps.

you allow yourself to live in the moment.
