B. Perform the System Restore
Inside the Recovery Console type the following commands to change the directory to the system restore directory:

cd system~1

If you get an Access Denied error:click here
If you don't get an Access Denied error :

cd _resto~1

If there is no _resto~1 folder or if there are no restore points inside it:click here

If the _resto~1 folder exists, inside it there are several folders named RP1, RP2. These are restore points. RP1 is the oldest restore point. You can use

cd rp3

Change the directory to snapshot:

cd snapshot

Restore the main registry branches. If you are being asked if you want to overwrite type in y to agree.

copy _registry_machine_system c:\windows\system32\config\system

The following commands are most of the time optional however the process might not work if they are not executed

copy _registry_machine_security c:\windows\system32\config\security
