Yes, I have been using, and have been very pleased, with CCleaner for several years now. However, the only reason I have not purchased the CCleaner's professional version is the "few" problems I have been experiencing.
In the past, I could run CCleaner Registry and the software would run as expected. Yet now, when I click on the Registry catagory the software the scans runs to about 17% then freezes and my system has to be re-booted in order to unlock it.
Does an administrator or senior user offer any suggestions on what could be causing the problem?
