I should also mention that the errors look like Windows errors but after testing SEP with Windows 10 from SEP version 12.1.6 MP1 to 12.1.6 MP4 I did the following:
- Install Windows 10 fresh on a clean device
- Fully update Windows
- Install each program that is need one by one IE Office / Adobe reader etc and after each install test windows for errors - non found and Windows running as it should
The problems start after installing SEP (SEP MP1 worked fine until the latest Windows update - SEP MP4 was released to fix the install error that is known) SEP MP4 installs as it should and updates but after the reboot that is when the errors start - they are Windows errors but if SEP is uninstalled Windows works as it should and I do not see the errors - install SEP again and the errors start again so there is an issue with Windows 10 and SEP, Symantec support have seen this in action!
So some users maybe having problems and think because they are Windows errors it is a problem with the OS but it seems that there is a compatibility issue with Windows 10 and SEP.
I will update once I know more
