Best Registry Cleaners to Fix your Windows Registry

Aregistry cleaner can simply be described as the oil needed to run the engine of your computer's operating system. As Windows begins a task, it will scan the registry for instructions. The data packets within the registry are unique to your PC configuration and installed software.

Important Update:
After our latest monthly evaluation, we are now recommending System Mechanic as the leading optimizer. Please see all of the best PC optimizers from our latest comparison results. They currently include excellent registry cleaners.

Since the registry continually changes as new programs are installed and uninstalled, it eventually becomes un-tidy and bloated. This may cause slightly sluggish performance and possibly PC freeze-ups or crashes.

Why do i need a Registry Cleaner?

Many programs leave behind residual data after un-installation. These orphaned registry entries build up and can slow PC performance. Considering Windows needs to access the registry constantly, it makes sense that a bloated Registry will force Windows to wade through unnecessary data to access its' current target. Since Windows will change values and write to the Registry, power blackouts, hard resets, and hard disk errors may damage the registry. Any errors that form can cause erratic PC performance that can lead to stalls and crashes.

WinASO

"WinASO can deliver advanced registry repair. Includes a detailed cleaning and registry file size reduction through full defragmentation."

WinASO Box and ScreenshotWinASO has "Registry Optimizer" as its' subtitle, but in reality, it really is on the verge of being a full system optimizer. unfortunately, we feel it's not feature-rich enough to compete against some of the better PC optimizers available.

It does contain some useful features like an excellent data recovery tool, for when you accidentally delete a file, plus a privacy cleaner to remove wasteful junk files. Of course, it's the registry functions that are its' strength. A tough choice between this and Registry Reviver.
