Is reimage safe ? you can read this  article to know more about it.

I came across this repair software when I was searching for alternatives to reinstalling Windows on a client’s PC. I was pretty sure there were a couple of viruses on the computer, as it was very sluggish, and after doing a few general fixes to the PC, a complete reinstall of the Windows operating system was necessary. At this point I decided to give Reimage a try to save some time.

Here are my findings:

By emulating the human brain and automating the way software problems are identified and repaired, Reimage has redefined the very concept of PC repair.

Reimage removes the guesswork in PC repair, removing the need for diagnostic decisions based on superficial symptoms. Reimage simultaneously studies every single software object and interlinked dependency, and compare this with a huge repository containing over 8 million objects. The technology then surgically pinpoints only faulty objects and dependencies. Throughout the process, user data and preferences remain untouched. The repository automatically corrects any malfunctions, with no need for prior preparation. The whole process takes no longer than 30 minutes, and the PC is as good as new.
