Hi,

At some time I've noticed I can't connect to Hyper-V on local laptop. When trying to start service "Hyper-V Host Compute Service" get error: "Windows could not start the Hyper-V Host Compute Service on Local Computer. Error 0x80070005: Access Denied."

Also, Even Logs:

Hyper-V detected access to a restricted MSR (Msr: 0x1F1, IsWrite: 0x0, MsrValue: 0x0, AccessStatus: 0x80, Pc: 0xFFFFF800B3F8501B,

ImageBase: 0xFFFFF800B3F80000, ImageChecksum: 0xC17D, ImageTimestamp: 0x5D313DAF, ImageName: semav6msr64.sys).

Yes, tried starting as administrator. Also Hyper-V was fine some time ago on same account.

Thanks,

Ivan

    Thanks Jason,

    I was able to find a solution by enabling below.

    Windows Security -> App and Browser Control -> Exploit protection -> Enable CFG

    Regards,

    Ivan
