The Windows Event Log on a machine running Workspace Environment Management may contain many events from the WEM Agent Service. These events all relate to processes for Antivirus software installed on the device. 

Workspace Environment Management 4.1 contains updated code that correctly identifies when an Antivirus software program prevents adjustment and does not log this as an error, as it is expected behaviour.
This version was released alongside XenApp and XenDesktop 7.12 in December 2016,

Problem Cause

Antivirus Software generally protects their related processes from adjustment by other processes in the operating system, such as WEM Agent Host. 
Workspace Environment Management 4.0, and Norskale VUEM Agent 3.5 before it, correctly identified this behaviour as expected but logged the event as an Error.
