Compatibility and Implementation of Virtual USB MultiKey 64-bit Drivers on Windows 11

Part 8: Alternatives – If You Can’t Get Multikey Working

The Multikey driver is not the only game in town. Consider these modern alternatives for Windows 11 64-bit:

Advanced Fix: Use a Custom Boot Loader

Tools like EfiGuard (open-source UEFI bootkit) can patch DSE at boot time without modifying Windows settings permanently. This is the most elegant solution for advanced users:

  1. Download EfiGuard v1.2+.
  2. Copy EfiGuardDxe.efi to your EFI partition.
  3. Add a boot entry using bcdedit to load EfiGuard before Windows.
  4. Windows 11 will boot with DSE disabled, but all other protections intact.

2. Hardware Clone Dongles

Instead of emulating, you can clone your physical dongle using a programmable device like the “Dongle Clone Pro” – but this requires hardware and is legally gray.

Method 1: Using the Command Prompt (Recommended)

This method uses the legacy hardware wizard to bypass some standard checks.

  1. Disable Driver Signature Enforcement:

    • Press Windows Key + I to open Settings.
    • Go to System > Recovery.
    • Under "Advanced startup," click Restart now.
    • After the PC reboots, go to Troubleshoot > Advanced options > Startup Settings.
    • Click Restart.
    • When the PC reboots again, press F7 to select Disable driver signature enforcement.

  2. Install the Driver:

    • Once logged back into Windows, open the Start Menu, type cmd, right-click "Command Prompt," and select Run as administrator.
    • Navigate to the folder containing your driver files using the cd command (e.g., cd C:\Users\Name\Downloads\MultiKey).
    • Type the following command and hit Enter: 
      devcon install multikey.inf root\multikey
      (Note: If you do not have devcon.exe, you can try right-clicking the multikey.inf file directly and selecting "Install," though this is less reliable on Windows 11).
