Yep, yesterdays' updates caused 95% of all machines to freeze up at work..... I can't believe they don't wait 30 days for updating in a work environment but they don't , and paid the price .
1 hour plus waits to log in , random disconnects , freezing, crashing .... what a nightmare.
Microsoft and Sophos have identified an issue on devices with Sophos Endpoint Protection installed and managed by either Sophos Central or Sophos Enterprise Console (SEC) that may cause the system to freeze or hang upon restart after installing this update.
