BSoD (Blue Screen of Death) appears with a stop error 0x50 in Win32k.sys driver during activity in Microsoft Office inside a container on a Windows Server 2008 R2 hardware node.


The crash happens due to a Microsoft issue in win32k.sys driver after installing a font update. It may appear only once for each container with MS Office installed.


Install PVC update VZU460065, as soon as it is released, and apply this Microsoft hotfix afterwards.

NOTE: If the hotfix installation shows "The update is not applicable for this computer", most likely, the version of win32k.sys is already newer than the one, provided in the hotfix. The version should be greater than 6.1.7601.18308.
