Notes

Windows 11

If the driver cannot be loaded properly, modify the following registry keys:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity]
"Enabled"=dword:0000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard]
"EnableVirtualizationBasedSecurity"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\SystemGuard]
"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Config]
"VulnerableDriverBlocklistEnable"=dword:00000000

Windows 7

For earlier versions of Windows 7, the driver may not work properly and requires a SHA1-signed certificate.

Windows XP

This project is compatible with Windows XP using YY-Thunks, but it may not retrieve some hardware information.
