“The Session Manager Initialization system process terminated unexpectedly with a status of 0xc000026c”
Caused by a recently Windows Update
First you need to access the recovery console. Following the instructions below
- Boot with your original Windows XP CD. You need one which will allow you to get into the Recovery Console.
- Once booted, choose to use the Recovery Console
- Choose which Windows installation you need to log into. if there’s only one on that machine, it will be “1?.
- Type in the Administrator password.
- Change to the update folder by typing cd WINDOWS$NtUninstallKB925902$spuninst
- Run this command in the folder: batch spuninst.txt (If the command ran correctly, you should see a spuninst.tag file, using the “dir” command)
- Restart the Computer
At this point the computer should boot properly and you should install SP3 and other patches to prevent this problem from happening again.
If the spuninst.tag file doesn’t exist, you may have received a bunch of errors instead. There are a few reasons why this could happen, one of which is if your windows isn’t really installed on the c: drive, even if the Recovery Console always names it that way. To remove the patch manually type in these command in the Command Prompt (By going back using the Windows CD instructions above)
