How can i change back my registry?

[Wyzo]

Hello guys...
Well...i managed to ruin my windows 7...now i don't know how bad....the idea is that i can use my laptop but i am logged in with a temporary account...
Yesterday night i was changing my user name in the registry...and i think i change quite a few registrys...and i can't use the system restore to go back ...
Is there any way how can i fix this?
How about if i try to modify registry back to my previous user?
In not....shame to me )
but hey...this is how we learn right?
Now actually i am planing to install a fresh windows 7...any way i was planing to change to 64 bit...
Best regards guys!

Yep, system restore would have saved your bacon if you had created a restore point before doing that.

You might see if starting over using the tutorial below may be able to help you fix your user account by changing everything back to what it was originally.

​

If not, then you might see if you may be able to create a new administrator account to use instead, and copy what you want from the old account.

Hope this helps,
Shawn

Also, for future reference, if you want to change your username / account name, use the "Change your account name" link under Control Panel > User Accounts.

To add to what has already been said, getting into the habit of making periodic images of your system drive should be an integral part of your backup policy! Its a lot easier to restore an image than it is to re install your OS!

This will show you how to create a system image (clone) backup of the entire hard drive or partition that Windows 7 is on, and any other selected drive or partition, to be able to restore the hard drive or partition at boot up back to the way it was at the time the backup image was created.

You have no System Restore points at all - even older ones? This is reckless since System Restore can save you in situations like this. I'd even apportion more disk space so more points hang around longer: System Protection - Change Disk Space Usage

Here are tips for getting a perfect clean reinstall - you can use either 32 or 64 bit with the same license: Reinstalling Windows 7

Obviously, it's too late now, but as well as creating a system restore point as suggested, you'd do well to back up the registry as well before you make any changes to it.

In fact, you'd do even better to leave the system registry alone.
