The stringent restrictions on the trial version make it difficult to analyze the effectiveness of the program. The trialware allows for only five sections of the registry to be repaired, and the compacter, defrag, and system optimization buttons were also hamstrung. During the trial, we recommend deselecting all of the errors discovered, and then carefully choosing which errors you think you can verify as being repaired to see if you want to purchase it. Registry Mechanic is a good program, but you won't get something for nothing here.
With a few and easy steps Registry Mechanic will scan your entire registry for any invalid entries and provides a list of the registry errors found. Then, you can choose to selectively clean each item or automatically repair them all. For your convenience and protection Registry Mechanic can also make a backup of any repairs made so that you can easily recover any changes if required.

System Mechanic's ActiveCare analyzes your system and runs common system cleanup and maintenance tools at regularly scheduled intervals, such as finding and removing junk files, cleaning the system registry, removing Internet clutter, getting rid of spyware, and defragmenting your hard drives.
Should you want to remove Iolo System Mechanic 7 Professional, there is no uninstall icon. You will need to use the Windows Control Panel, then Add or Remove Programs. After a reboot, we discovered several system registry entries and program folders and files remained for System Mechanic 7 Professional. We do not recommend deleting the system registry entries without technical support; however, deleting the program folder required us first to change its read-only status. Only then could we delete the program entirely from our machine.
Conclusion
Based on past performance, we eagerly awaited System Mechanic 7 Professional, only to be disappointed. Instead of a pure system-utility suite, Iolo has played up the security features in this release--and may have taken on too much. Frankly, there are too many tools in this suite and not enough information about what all of them are doing to your computer. Also, the occasional glitch tended to undermine our confidence in System Mechanic 7 Professional's ability to accurately tweak and optimize our PC. Think long and hard before handing your computer over to a product such as this, that can change your system registry files and defragment your hard drive without providing much detail before and after the fact, or much in the way of live technical support should you run into trouble.
