Windows 8 Pro cannot boot - Error 0xC000021a

Hi

I upgraded my son's laptop from Windows 7 to Windows 8 Pro. I has been working fine for a few weeks. But now when booting It halts iwth the error code 0xc000021a. I have tried the following options

Refresh - this fails with the error 0xc000021a

System Restore - this fails with 0xc000021a

Safe mode boot does not work

I can start the cmd console

Any suggestions as to how to proceed?

No need of anything like that. I had used an app called 7tsp to change my windows look. When I rebooted after the patch i found this problem. So i decided to go to system configuration or something with a name like that. There would be a list of dates available on which there have been downloads. I clicked a date which was one week before the day the error came. Then it started to load. 1 hour later it is as good as new. I had overcame this problem and I am also replying the solution on the same laptop that received this error.

No need to worry about throwing away yr laptop. This error can be fixed
