Hello, today I've been messing with some software tools like defrag and registry cleaner then i restarted my pc and now im getting blue screen with this error: 
STOP: c000021a {Fatal System Error}
The initial session process or system process terminated unexpectedly with a status of 0x00000000 (0x00010828).
The system has been shut down.

I've already tried system recovery but it fails everytime aswell as the repair tool. Also I downloaded some important Windows 7 update today so I did a bit of googling and I found out that this type of error happened to some people after updating their windows. So I tried to delete the latest windows update using command prompt in system recovery optains but that says that im not authorized to do that even tho I logged in as administrator.
I've got no idea what else to do can anyone help me with this?

Sounds as if you will need to do a system repair which requires the installation CD.  Registry tools can do far more damage then good!

Since the issue started after cleaning the registry , i would suggest starting with replacing the probably corrupted registry hive files from the backup copy. The hive files will be located inside "C:\Windows\System32\Config" folder and a backup copy will be stored inside "C:\Windows\System32\Config\Regback" folder. You can use either a Windows installation disc or a "System repair Disc" to perform the replacement.


Please refer the below guide (ignore the heading) and let me know whether it helps.
