Regtweaker scans your computer registry for anomalies and fixes it. Benefits of cleaning up your registry include faster computer performance, less blue screens of death, less freezes or crashes, and and overall increase in efficiency and reliability. The registry is where any program that gets on your computer stores its information and basic settings, like whether or not it will start automatically when you start your computer. With Regtweaker, you can automatically clean up this registry, which improves your bootup speed by only letting the programs you actually use start automatically. Other features include cleaning up your caches, junk, and temp folders, as well as a network optimizer and a number of Internet Explorer tweaks. Overall, Regtweaker could be a good idea if you feel like your computer performance is getting worse.
