New hotfix: Software update installation freezes on Microsoft Configuration Manager clients

During an Operating System deployment (OSD) of Windows 10 via System Center Configuration Manager, the Install Software Updates task sequence may freeze when large numbers of updates are applied (e.g. 50 or more). When this problem occurs, the CCMExec and TSInstallSWupdate processes appear to hang. If the thread count is monitored with Task Manager or other tools, the TSInstallSWupdate process shows that approximately 774 threads are in use.

This problem occurs in ConfigMgr 2012 SP2, ConfigMgr 2012 R2 SP1 and ConfigMgr 1602. If you encounter this problem, a supported hotfix is now available from Microsoft. See the Knowledge Base article below for details.
