RegShot is a small registry compare utility that allows you to quickly take a snapshot of your registry and then compare it with a second one - done after doing system changes or installing a new software product. The changes report can be produced in text or HTML format and contains a list of all modifications that have taken place between snapshot1 and snapshot2. In addition, you can also specify folders (with sub filders) to be scanned for changes as well.

What can I do with REGSHOT?

Windows itself or some system-optimize program may change your registry,you might wonder what they have done?

Many suspicious programs left trashes in your registry or in the file system,all those are done without notification!

RegShot can trace what they have done and clean the Mark they left!

You can use UNDOReg to help undo the entries.
