BTW, I did fix the error. Turns out I was in a public network and the rule only applied to domain networks.
Also these fucking rules don’t show in the usual GUI, you have to look into the registry.
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\Mdm\FirewallRules

You could download stressapptest and run that memory benchmark in the normal system.
I’m not sure how well the current version of Memtest does, but when I was overclocking I was told not to use it as it couldn’t reliably get memory to crash. (Funny problem to have). The two recommended tools are Windows only, so I found stressapptest as the best alternative.
