Portable MV RegClean
MV RegClean is a tool that scans your computer for any problems concerning your Windows registry entries and fixes them.
Since this is a portable application, the program doesn't require any installation. So, you can place MV RegClean on an external device and run it on any computer.
The user interface is plain and simple. Once you initiate the application, a scan is automatically initiated (which can be canceled at any time).
You can view file paths and information about any found problems, once you have selected a particular file. In addition, you can view the time it took MV RegClean to process data (start and end time), as well as total keys, values and problems.
Thus, you can export the list of registry entries to a TXT file, select or deselect all keys, and then proceed with the cleaning process.
If you are worried about backing up the registry file, then you should know that MV RegClean automatically performs a backup before you remove anything from the list. This means that in case any errors occur with your operating system, you will be able to restore files. In the "Backup" area, you can view the date and time for each backup.
In the "Options" section, you can change the appearance of the interface (choose from 12 skins), add registry keys that will be ignored during scanning, and disable the program from creating a backup file before removing invalid items.
MV RegClean uses a low amount of system memory and can take a while to finish the scanning process. However, it removes items very quickly and didn't cause us any problems during our tests.
Furthermore, the application comes with a step-by-step guide (contains snapshots). On the other hand, we would have liked the possibility of choosing a scanning mode (e.g. quick, full, expert).
All in all, MV RegClean is a great tool for cleaning up invalid Windows registry keys, and we strongly recommend it to all users.
