Uniblue RegistryBooster 2.0

Uniblue registry booster 2 is the best registry scanner / cleaner available.
It has all the features necessary for a registry scanner, with the most comprehensive information to scan windows registry. ActiveX, Invalid file associations, uninstall sections, invalid font associations, application paths, shared folders, Invalid shortcuts, etc are some of the options.

It lists / finds more number of registry problems than any other registry cleaner you will get. Also, many registry cleaners do a lot of unwanted changes to the windows registry that causes system instabilities and slows down windows altogether instead of speeding up. But Uniblue RegistryBooster is really safe.

It has also the facility to defragging the registry file. Defragging means to arrange the parts of a big file that is scattered in many places in a hard disk in contiguous disk locations. Since the registry file in windows has a high chance of getting fragmented, it is a good idea to defrag if you have the habit of installing and uninstalling a lot of softwares or games. Registry defragging is really safe and easy with this program.

One tip, don't select the "Drivers" option for scanning unless you are scanning for that specific problem (or if you know what you are doing, like for troubleshooting a driver installation,etc). Anyway, this program is really safe.
