Hello all, Consider I start working on a Windows 7 machine. When exploring it I see there are many changes that have been occurred by Registery entries. To solve them I need to go to the path and modify each one. But I think there should be some simpler way, say a tool. I know there are many tools/apps, but I don't know which ones are really reliable. Is there any reliable software for returning the registery keys to their default states please?
