Microsoft Windows Server 2008 R2


A small number of Windows 7/Server 2008 R2 systems become unresponsive during a system startup and after applying a Windows update.

The issue is random and affects a limited number of systems. For example, only 80 systems would see the problem out of 18,000 that applied the Windows Update.


A thread in the process Wininit.exe becomes blocked while waiting on a validation attempt in McAfee Validation Trust (VTP). Wininit.exe is locked because it is the same resource needed by VTP for the verification, which leads to a deadlock on Windows 7/Server 2008 R2 systems.





Perform a system restart to allow the system to recover.
