I am using XP professional and cannot logon anymore since automatic update

has installed some critical updates. After booting successfully the system is

asking me for a password, although I have never specified one!How can this

happen?



I am the only user and have tried several passwords including username.

leaving blank ect. but have no idea what it could be. After a few attempts it

comes up with the following error message:



The system cannot log you on due to the following error: The program issued

a command but the command lenght is incorrect. Please try again or consult

your system administrator.



Can anybody help me please?



Thanks

Reino

Hi james,



have solved the problem, nothing helped then I had an idea and tried it the

easy way:



press F8 during rebooting your machine until it comes up with some options

(Safe Mode ect. ect.) and choose the following:



start windows with the last known good configuration



it will start up normally now, without asking you for a password because it

remembers the windows configuration from before you have installed your

critical updates which have caused this problem.......so its excluding them

automatically.



Just make sure, that you dont install them again and deactivate the

automatic update or follow instructions for automatic logon.

I have the same problem.

I think the problem is installing security update KB885835 from Microsoft. 

This is the last update that I installed before this error message. 

Solution: Do not trust to the automatic update just turn it off.
