When shutting down my Windows XP home edition system, Windows appears to shut down but then gives the following blue screen message:

STOP: c000021a (Fatal System Error)
The Windows Logon Process System process terminated unexpectedly with a status of 0xc0000005 (0x0000000 0x00000000). The system has been shut down.

I can power down the computer with the power button and can log on again without problems. I have all Windows updates installed. Recent computer changes include installation of IE7 and automatic installation of MSN explorer 9.5.
Help appreciated.

Heres another forum answer. This may not be the answer for you since it has to do with a dual boot linux/microsoft system.

you don't appear to have a boot problem.
you seem to have a WinXP start-up problem.

can you boot WinXP in Safe mode?

you'll need to type F8 just after selecting either Windows grub entry
and before the WinXP "green caterpillar" appears. Choose "Safe Mode".

The equivalent registry keys for the ones mentioned in the referenced
Microsoft KB317189 are:

(Note that in WinXP the 'hive' loading and unloading is unnecessary)

1. for finding the current control set (HKLM == HKEY_LOCAL_MACHINE)
- HKLM\SYSTEM\Select
- check value of Current

2. for finding pending file rename operations
- HKLM\SYSTEM\ControlSetNNN\Control\Session Manager\FileRenameOperations
- (where NNN is the three digit leading zero decimal value of 'Current' above)

3. for finding the RunOnce and RunOnceEx entries
- HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
- HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx

It seems a software upgrade or OS patch install of yours has gone awry.

Standard warnings about editing the Windows Registry apply.

more info on status 0xc000003a:
#define STATUS_OBJECT_PATH_NOT_FOUND ((NTSTATUS)0xC000003AL)

meaning: the Session Manager Initialization couldn't find something..

SRX660. Thank you for your detailed response, and apologies for delay in replying. I think the problem related to the IE7 and MSN Explorer 9.5 updates. A separate, but actually I think connected, problem after the MSN 9.5 update was that on exiting the dial-up connection, the phone did not in fact disconnect. It appeared after experiencing this for several days, that the Windows close-down problem only occured after the MSN phone problem. MSN acknowledged the phone connection problem and this was solved by an automatic MSN Explorer update. Since then the Windows close down problem has not recurred. Perhaps this may help others who experience the same problem.

Please start your own topic as this one has not had a response in over 3 years.
Although your issue may seem similar there can be other factors that may need to be resolved.
By bumping on someone's topic it makes it confusing for the tech to understand who they are helping. This can in turn cause the wrong support to be given and can cause instability or worse to happen to your system.
Thank you for your cooperation.
