I have a Windows 7 Ultimate Notebook (Acer 1420p - PDC edition) that sometimes hangs at the "Logging off..." screen.
The Eventlog has the following entries:
- 18:13:51 Warning: The winlogon notification subscriber Profiles is taking long time to handle the notification event (Logoff).
- 18:12:51 Information: The winlogon notification subscriber SessionEnv was unavailable to handle a notification event.
- 18:12:51 Information: The Desktop Window Manager has exited with code (0x40010004)
The machine has all Windows Update fixes installed. I am unable to reproduce the problem immediately after startup but it will happen if the machine is running for some time (with suspends/hibernate).
Any ideas on what's the problem or how I could diagnose it?
