问题
Anyone out there run into this? :
Seeing Win7 Ent machines show black screen and go unresponsive when switching users or logging out while the SCEP client (Microsoft's AV client supplied with SCCM) is enabled. If I disable it, the issue goes away. Just started happening yesterday. Ran through Windows update reset, SFC, update troubleshooter, update readiness tool, updated latest to latest video card drivers, removed updates deployed in the last round, to no avail. Issue goes away in safe mode, but in clean boot with MS services running, it still happens, so 3rd party stuff ruled out.
Engaged MS support, waiting on a call.. just wanted to know if anyone has found an easy way to fix this
TIA
回答1:
use MpCmdRun.exe to remove definition (MpCmdRun.exe -RemoveDefinitions -All) and search new update definition, this solve the problem.
