Novell ZENworks 10 Configuration Management with Support Pack 2 - 10.2
If a Windows 7 64-bit Device is remote controlled, "Desktop Windows Manager" will be permanently disabled, which also results in Aero being disabled.
Even a reboot of the Device will not re-enable Aero.
As a workaround, Remove the "Mirage Driver" from the "Display Adapters" section of "Device Manager ".
Note: Removing this driver will result in reduced performance during remote control sessions.
StatusReported to Engineering
"Desktop Windows Manager" is disabled during remote sessions since ZCM uses the Mirage Driver, which is a mirror driver, to improve remote control performance.
By Windows Design, "Desktop Windows Manager" is disabled when a mirror driver is loaded.
