Disable Hyper-V and turn off core isolation

The technologies used by Microsoft's "Core Isolation" and "Hyper-V/VBS" conflict with MuMu Player 12, causing the emulator to run inefficiently or not run at all. It is recommended to turn off "Core Isolation" and disable "Hyper-V/VBS" when running MuMu Player 12.  Turning off core isolation will not affect security. If you are concerned, you can install other security software. You can turn off core isolation and Hyper-V/VBS by following the steps below:

1. Turn off core isolation

Go to Windows Settings - Update & Security - Windows Security - Device Security - Core Isolation Details and turn off Memory Integrity;
