For example, if a blue screen appears in windows XP or any Win OS, we cannot enter into the system. Restoration to a old date is also not possible as we could not able log in to the system.. In this situation, we are left with only one solution. Just the "Brain Operation"
Put the XP Live CD in the CD Drive and reboot the machine.
select miniXP
Go to C:\System Volume Information\RP1\snapshot
(RP1 may be replace with any of the latest restoration point. RP1 or RP2 or RP3 etc)
copy the following files
_REGISTRY_MACHINE_SAM
_REGISTRY_MACHINE_SECURITY
_REGISTRY_MACHINE_SOFTWARE
_REGISTRY_MACHINE_SYSTEM
_REGISTRY_MACHINE_DEFAULT
paste these files in the following folder
C:\windows\system32\config
rename the existing SAM, SECURITY, SOFTWARE,SYSTEM,DEFAULT files to SAM1,SECURITY1,SOFTWARE1,SYSTEM1,DEFAULT1 etc.
rename above files to
_REGISTRY_MACHINE_SAM ----> SAM
_REGISTRY_MACHINE_SECURITY ---> SECURITY
_REGISTRY_MACHINE_SOFTWARE---> SOFTWARE
_REGISTRY_MACHINE_SYSTEM-------> SYSTEM
_REGISTRY_MACHINE_DEFAULT------> DEFAULT
now remove the CD and start with windows you prefer.
Thats all folks. The Brain Operation is over.
