Data Center | 22. April 2016 | Robert Haneberg WSUS Service stopped – do not install KB3148812 on Configuration Manager or WSUS serversLast week Microsoft released Patch KB3148812 on Windows update. So this week we installed it on a customer ConfigMgr Sites (1x CAS, 2x Primary) due to an maintenance job. The KB article says something about enabling ESD encryption for WSUS:https://support.microsoft.com/en-us/kb/3148812So here is my advice:DO NOT INSTALL THIS UPDATE on WSUS or SCCM Servers!!!At our environment it broke the WSUS Service completely.
