It's a lot more tame than, say, CCleaner, which prompts you to remove things that could be important.
TweakNow PP also has a mild cleaning option and the Start-up Manager---you can stop meaningless programs from starting up. If I'm you I'd run Glary to clean the registry and TweakNow for more advanced options.
14 MB for both. Not bad.
