Getting back the Registery to its default situation

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?

Did you create a backup for the registry before modifying the registry. If not, there's no way out. You gotta do the entire rebuilding yourself . Or even a system restore to a stage before modifying would help. Still negative then do a total system recovery using a recovery disk.

----------> And, finally, the only way is to re-install your Windows 7 <---------------------------------

*Just in case to remind you, there's really no such program that can restore your registry settings *

It's better to always have a backup file before you modify the registry.

Without knowing what your computer is, or isn't doing, it's hard to offer a specific suggestion. If the changes to the registry were all done around the same time, you might have a system restore point that would return your computer to an earlier time (before the registry changes were made.)

System Restore

But if the registry changes were made over a long period of time, or if you don't have any restore points, then you're looking at several individual tools/scans that might help. For example, you could run a System File Checker scan, Startup Repair, Checkdisk, etc etc. Take a look at the response by SpirtX in this Microsoft Forum.

If it was my computer and I was having multiple problems, I think I'd go directly to a Repair Install. If successful, it will preserve your user accounts, data, programs, system drivers, etc while returning your registry to its default configuration.

Repair Install

If none of the above fix your issues, then I'd do a clean install. Once my machine was back to normal, I'd make full system images on a regular basis. Then you could experiment and tweak your computer knowing you could restore it to a good image in usually less than an hour. A lot of people recommend the free Macrium Reflect.

Yeah, I meant the same.

Thanks to both of you. I think the most useful one is repair install.
