When navigating to Computer > Policies > Windows Settings > Security Settings > Local Policies > Security Options, MMC crashes with the error: "MMC cannot initialize the snap-in" and no settings are loaded. The same behavior can be seen when editing directly in GPMC.
原因
This is caused by a Microsoft security patch affecting Windows Server 2016. https://support.microsoft.com/en-us/help/4577015/windows-10-update-kb4577015 https://docs.microsoft.com/en-us/windows/release-information/status-windows-10-1607-and-windows-server-2016#1482msgdesc
解决办法
The only workaround at this time is to roll back the security update if it is applied.
