Under the folder "System Volume Information\_restore{GUID}", there are subfolders called RPx where x is a number, the highest number is the latest Restore Point.
In the RPx folder, there is a subfolder called snapshot, which contains all the registry hives.
In essence its these snapshot folders that you'll have to save separately
If your machine ever gets into a no-boot situation you can follow these steps to manually perform the system restore:
Step 1:
***************************
Boot with the windows XP CD
At "Welcome to setup screen" Press R
Select the appropriate path for windows and press enter
If it asks you for the administrator password, type the administrator password and
press enter or just hit enter
We will now see the Prompt c:\windows>
Step 2:
***************************
cd system32\config
ren system system.old
ren software software.old
ren SAM SAM.old
ren security security.old
ren default default.old
cd
Type cd system~1\_resto~1 and press Enter
If you get "access denied" (Error) then
Restart the computer by type Exit and get back to recovery console
type cd \ and it will display C:\>
type cd system~1\_resto~1 and press Enter
Step 3:
***************************
Type dir
It will list you restore points
(e.g. RP1, RP2, RP3, RP4, etc...)
Select the one from the list except the last one
Say RP4
· type cd RP3 (or RP2 or RP1 or RPn) and enter
· type cd snapshot and enter
· type copy _registry_user_.default c:\windows\system32\config\default and enter
· type copy _registry_machine_security c:\windows\system32\config\security and enter

· type copy _registry_machine_system c:\windows\system32\config\system and enter

The computer restarts and the system will be successfully restored
