Limit Windows Defender CPU Usage
I have the problem that our Clients use too much CPU during a FullScan. Actually, the usage is limited to 20%, but the setting seems to have no effect. Whether I set it via Configuration Manager or G...
Have the same problem as philippwree!
In the Configuration Manager, we defined a CPU load of 30% for our windows servers in the default defender policy. The setting has also been correctly transmitted to the agents.
Checked local via powershell "Get-MpPreference" and in the registry "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows Defender \ Scan \ AvgCPULoadFactor". The values are correctly limited to 30%.
Despite the throttling, the process "MsMpEng.exe" uses up to 100% CPU for scheduled and manual defender scans (full and quick).
Possibly a bug in a microsoft defender update?
Yes... It would be great if the setting actually worked, eh?
