The other day we found a computer giving this error and continuosly resetting:

STOP: c000021a {Fatal System Error}
 The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000135 (0x00000000 0x0000000)
The system has been shutdown


We reviewed kb156669 and it says some causes:

•Mismatched system files have been installed:  "No as far as we know"
•A Service Pack installation has failed:  "No as far as we know"
•A backup program that is used to restore a hard disk did not correctly restore files that may have been in use:  "No as far as we know"
•An incompatible third-party program has been installed: "No as far as we know"


We resolved the problem copying the folder system32 from a new computer to the old but the question is if someone know how to troubleshoot this and to know exactly the cause.


Thanks in advance.

The previous person that used it might have added dual boot with linux and edited the .Ini boot file.


You understand that the system32 folder contains a folder called drivers, which contains the drivers related to the software installed on the operating system?


So basically copying the system32 folder from another pc, and expecting all software to run fine is not going to work out well for you.

For example, here i have 2 pcs, pc A and pc B.


Pc A has avast and malwarebytes software installed.  Pc B has Microsoft security essentials and SuperAntiSpyware installed.  How could i expect the system32 folder from pc A, to have the correct drivers for pc B?
