Getting back the Registery to its default situation

[abbasi]

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?

Yes, just reinstall the OS on an empty partition.

Thanks for your opinion.

Gbhall is correct. I'll add that it's a good idea to stay out of the registry. I use CCleaner (free) occasionally to tidy things up but I'm confident that the computer is going to start up afterwards.

Thanks for your idea as well.
