Logout and Application Memory Error

[Guest]

After applying the latest updates, whenever I log out I get an error message
to say that stylexpservices.exe and winlogin.exe can not read a memory
address. The address is something like 000x000000.
I'm not too sure of the exact wording as I'm not with the computer at the
moment.
It still shuts down fine, even without selecting any of the buttons in the
dialog box, but it is annoying to have something like this pop up.

Any one else reported a problem like this and have a fix?

I have tried this in the Update section but to no avail.
