Make sure you check these first
- Run VTCheck.exe and make sure you have all the “green ticks”. If not, go to BIOS settings and make sure all “Virtualization” or “Intel VT-x” related settings are enabled.
- Make sure you do not have any Antivirus installed (even disabled they may interfere with kernel activity).
- Do not forget to add an exception for the WMB Folder and the temp file that gets created at Windows Defender (click Manage settings under Virus & Threat Protection > Add or Remove Exclusions). Then Run WMB (it will still fail, because you need to also allow the temp file) and click on Protection History and allow the temp file (it will have a random name).
- Real Time Protections setting in Windows Defender should also be disabled.
- Uninstall all virtualization tools, including VMware, Hyper-V, Sandbox (Windows features), Android Simulators.
- Uninstall all Anti-Cheat platforms such as “faceit” or “riot vanguard”.
- Run this command in CMD “bcdedit /set hypervisorlaunchtype off” and reboot.
- Make sure Memory Integration (a Windows setting) is disabled.
- On some Windows hosts with an EFI BIOS, DeviceGuard or CredentialGuard may be active by default, and interferes with OS level virtualization apps in the same way that Hyper-v does. These features need to be disabled. On Pro versions of Windows you can do this using gpedit.msc (set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security to Disabled.
