Kingsoft PC Doctor Free v3.7

A full review of Kingsoft PC Doctor, a free registry cleaner

Kingsoft PC Doctor is a program suite, which means it can perform several cleaning functions to your computer in addition to being used as a registry cleaner.

For example, it can be used to find large files on your hard drive, uninstall programs, and clean junk files.

The registry cleaner in Kingsoft PC Doctor is fast, simple to use, and makes it easy to identify why a particular registry item is marked as containing an error.

My Thoughts on Kingsoft PC Doctor

Some program suites that include a registry cleaner make it hard to clean just the registry because of all the other tools.

Kingsoft PC Doctor, however, has a dedicated section for registry cleaning so you can use just that portion of the program if you want, which is really nice.

It's unfortunate that there are no scheduling options for cleaning the registry when you're away from your computer, but hardly any other free registry cleaners offer this feature, so we can hardly complain.

Kingsoft PC Doctor seemed to find a similar number of problems with the registry as other registry cleaners did.

We recommend this program not only for its registry cleaning capabilities but because of all the other useful tools that are included.
