Registry Reviver 4.0 Review

Author by

PROS / Registry Reviver has a setting to automatically create a restore point before you make a repair.

CONS / Without an undo tool, you can't easily reverse single registry repair mistakes.

 VERDICT / Registry Reviver's easy-to-use interface and automatic safety features make this a good choice if you have never used a registry cleaner before. However, the lack of a specific undo feature means that any mistakes will require a full registry restore.

ReviverSoft developed Registry Reviver as an easy way to optimize your PC's registry and improve overall performance. The interface has a logical design that makes it easy to learn, even if you've never used registry cleaner software. Immediately upon launching the software, you can read information about the hardware of your computer, including the system's overall health. In addition, the registry scanner provides options that allow you to customize which areas of the registry database you want scanned. The comprehensive scan of our test computer's entire registry took 48 seconds and found 89 registry issues.

The scan summary provides detail that's comparable to the top Microsoft registry cleaners. For example, from the scan you can view the fragmentation percentage of the registry – a detail not included with most registry cleaner's scan summaries. To fix the fragmentation, a defrag tool is included to optimize the registry, which is intended to improve your computer's performance. After running the defrag and repair tools on our test computer, however, we suffered a 6.71% performance loss. This PC cleaner doesn't compare to the best registry cleaners, which can increase PC performance by up to 5.31% percent.

Since making any changes to your PC's registry database can be risky, safety features are critical in a registry cleaner. Most registry tuners require you to back up the registry manually, which puts you at risk of forgetting to create a backup. However, Registry Reviver includes an automatic backup feature that backs up the registry before every repair you make. These automatic backups act like a safety net that allow you to make mistakes because you can restore the registry by using one of the automatic backup points.

One flaw of the safety features is the lack of an undo tool. This a common feature among the best registry optimizers because it allows you to reverse minor mistakes when you're using the repair tools. For example, if you accidentally delete a critical registry file, an undo tool would simply reverse that one mistake. Without it, the only way you can rectify the mistake is to restore the entire registry database from one of the backups, which is not only time consuming but erases any progress you may have made in other areas of the registry.

For help and support, you can access a FAQs page and a forum for quick answers on ReviverSoft's website. You can also email or use the 24/7 phone support hotline. The only support feature missing is live chat.


Registry Reviver's logical interface and automatic backup features make it a good registry tuner for novice users. However, the registry repair and defrag tools didn't result in an increase in our test computer's performance. In addition, the lack of an undo function means that any mistakes will require a full restoration of a registry backup to fix.
