Help!
After the latest updates on Windows Update I can't boot my laptop (an HP Envy Ultrabook 4). Every time I try to start the computer it first goes into repair mode (where none of the solutions have worked so far) and subsequently displays only a blue screen with the message:
"STOP: c000021a {Fatal System Error}
The verification of a knownDLL failed, system process terminated unexpectedly with a status of 0x000012f (0x003a6e70 0x00000000). The system has been shutdown".
The only thing I can do after that is to restart the computer manually and thus the whole procedure starts over again. I have tried to run chkdsk /r /f and sfc /scannow in cmd.exe (from the repair menu) and change a number of values in regedit.exe, but nothing has worked so far. Can anyone help me solve this problem? (I'm relatively sure that it is not due to hardware problems; the computer worked perfectly before the update).
Thanks in advance!
