  • Not sure - haven't had a chance to look at it in more detail... but this is from the earliest startup log when PC was having the problem.

    We did get the laptop working again...but not ideal - and at moment Sophos want to just close the ticket because we manually got the device back to working state.- but it leaves me concerned as this happened to be the first device that got the Windows 2020 H2 update. As of yet, I don't know if an isolated incident or going to be a general problem taking the laptop out of Self-isolate policy on Sophos central.

    2.manually restarting Sophos Device control service ( antivirus service still failed and showed as red status)

    3. reboot Laptop

    3. push a manual update from Sophos central.

    4. could see on the laptop - Sophos receiving an update.

    5. once update completed - after a couple of minutes - Sophos status showed all green (antivirus started) - and laptop back to normal.
