Windows registry is a database that stores all the configuration features of the operative system. Over time, it gets clotted since it records many of the events in our system, such as installing and uninstalling programs, and so on. This program analyzes your registry to detect and fix several types of errors, such as system-related, Com and ActiveX, user-related and Startup and uninstall errors. You can let the program scan all these options automatically, or select only those you need. You can set it to perform a scan every time Windows starts, as well as to schedule scans at any given hour and day. You can also exclude any registry entries that you don't want to analyze.
The program works fast and before making any change, it allows you to make a backup copy of your original registry so you can undo the changes if you need. An important drawback of the program is its high cost, although it offers a discount and another program for free. The developer claims that it performs an advanced scan of the registry, but I couldn't find any substantial difference when compared with other more affordable or even free registry scanners.
The shareware version only allows you to fix 15 of the errors found by the program. If you find it useful and want to get rid of this limitation, then you must purchase a license which, as I've said, although is not very affordable, has a discount and includes another program for free.
