CAUSE
The first symptom that is mentioned in the &quot;Symptoms&quot; section is caused by a deadlock between the Tablet PC Component and the Winlogon.exe process. After a thread in the Winlogon.exe process acquires the loader lock, the thread queues a local procedure call message to the Winlogon.exe process.
