If you search this forum you will see that others have had the same issue with Persona on Agent versions 7.5.0, 7.5.1, and 7.6.0. Generally, the workaround is to take your Agent back to 7.4.0. I have seen one post that claims the Persona issues are fixed in the new 7.7.0 Agent. I have not tested this claim, so I cannot substantiate it. Obviously VMware would prefer that you switch to UEM, but until they make some form of UEM available in Standard and Advanced versions of Horizon, they will need to continue to support Persona with WIndows 10.
