Riot Vanguard ByPass for League of Legends

8 min read

Things you need:

Steps:

  • Go into Hyper-V and Make a Virtual Switch (Can use your Ethernet)
  • Go into the extracted folder you downloaded from Neggles - Hyper-V GPU Virtualization
    • There will be 2 .ps1 files and 1 readme.md
    • Right click and edit ‘New-GPUVirtualMachine.ps1’
    • Change VMName, VMMemory, VMCore to whatever you like and save
    • Run powershell as administration and run the command
Set-ExecutionPolicy bypass

  • and select Y Yes and then close powershell

  • Right click in the folder and open Terminal

  • Type ls to check if the 3 files are showing which would indicate you are in the right folder

    • (New-GPUVirtualMachine.ps1, New-GPUDriverPackage.ps1, readme.md)

  • Type .\New-GPUVirtualMachine.ps1 in Terminal or alternatively you can just write ‘./’ and press tab until you get the file

  • This file creates your vm in Hyper-V

  • Check your virtual machine that you created and change these settings going forward

    • Check Processor count in your virtual machine as it may have not saved and it might be using the default value (1).
    • Add the Virtual Switch that you created in the Network Adapter Tab
    • Go to “SCSI Controller” and add a DVD Drive
      1. Choose Image File and select your Windows ISO that you want to install and select Apply
      2. This time select ‘Hard Drive’ and click Add
        • Select Virtual Hard Disk and click New
        • Choose Fixed Size if you are planning on playing games
        • Name your Hard Disk
        • Choose an appropriate location for all your virtual disks. Note, this location must have good amount of storage as all your virtual drives will be here
        • Select the size you want for your Virtual Hard Disk (Default 127GB is plenty, adjust accordingly to how many games you plan to install)
        • Do note that Windows Server 2025 and 2022 take approx. 15GB storage
    • Once all the drives are made go into Firmware and change the boot order. It should be in this following order:
      → DVD Drive (Boot Drive)
      → Virtual Hard Drive(s)
      → Network Adapter

  • Now double click your VM and start the installation for your Windows

    • DISCLAIMER: IF YOU GET AN ERROR WHEN STARTING YOUR VM FOLLOW THIS —
      In my case, the error was somewhere along the lines of:

      GPU Partition (Instance ID 69E7E377-A066-41D6-A03B-E610AC30DAA6): Failed to Power on with Error ’.‘.Insufficient system resources exist to complete the requested service

      ‘WS22PLEX’ failed to start. (Virtual machine ID CAED9896-6895-4541-AC43-B25856D3B385)

      ‘WS22PLEX’ GPU Partition (Instance ID 69E7E377-A066-41D6-A03B-E610AC30DAA6): Failed to Power on with Error
      ’Insufficient system resources exist to complete the requested service.’ (0x800705AA). (Virtual machine ID
      `CAED9896-6895-4541-AC43-B25856D3B385)

      Could not allocate a GPU partition as no GPU devices are compliant with currently set group policy. See
      HyperV\RequireSecureDeviceAssignment and HyperV\RequireSupportedDeviceAssignment for more details.

      To get around this, you need to create 2 keys in Reg edit.

      HKLM:\SOFTWARE\Policies\Microsoft\Windows\HyperV" -Name "RequireSecureDeviceAssignment" -Type DWORD -Value 0
      HKLM:\SOFTWARE\Policies\Microsoft\Windows\HyperV" -Name "RequireSupportedDeviceAssignment" -Type DWORD -Value 0

      I closed off MMC.exe from Task Manager before attempting to run the VM again.

      Try to launch the VM again by running the following command in Powershell: Start-VM Server123
      (Replace “Server123” with your recently created guest server name).

      Your server should now boot up with no error. I installed drivers in the guest and tested by running a 4K youtube video, and watched the resource spike up on the host machine’s task manager.

      Notes:
      • Make sure that you install GPU drivers on the host machine before doing any of the above.
      • Make sure to install GPU drivers on the guest VM when after creation and booting into it.
      • Normally, GPU resources are not visible in the guest VM.

  • While your windows is downloading, now run the second .ps1 file in the same terminal

    • This file will make a zip file of the GPU Drivers in the location of the .ps1 file
    • Transfer this zip file onto the VM either through swisstransfer or a cloud drive like onedrive
    • Extract the zip file and paste the contents into C:\Windows\
    • Now Shut Down the VM

  • Open Powershell as Administrator on Host System

    • Type [Set-VMProcessor -VMName YourVMName -ExposeVirtualizationExtensions $true]
    • You wont get any outputs for this
    • Once this is done open your VM

  • In your VM go to Apps and Features and Enable Hyper-V

    • If you are on Windows Server go to Server Manager → Add Roles or Features → Hyper-V
    • Restart VM
    • Nested Virtualization Enabled

To check if you successfully passed your GPU

  • Go to Device Manager → Display Adapters
  • You should be able to see your GPU if you have done the steps right
  • Sometimes GPU shows on the Task Manager on some windows versions

Things you need in order to play games on your VM without latency:

SETUP →

  • Install ‘usbipd-win’ on host computer and install ‘usbipd-win2’ on VM
  • Install ‘Virtual Display Driver’ on VM
  • Open Powershell as Administrator and write [usbipd list]
    This will show a list of your connected USB devices
    Find the mouse that you want to use in the VM to play games and note its BUSID
  • Write [usbipd bind —busid 1-8 —force], here I have written my busid for my mouse which is [1-8] you write whatever yours is
  • Depending on your mouse it will ask to reboot your host machine
    NOTE: In order to unshare or unbind the mouse → [usbipd unbind —busid 1-8] on your host machine
  • TIP: Enable Mouse Trails by going Mouse Settings → Additional Mouse Settings → Pointer Options → Display Mouse Trails → Check and select the shortest option
  • When using mouse through usbipd-win and usbipd-win2, even though mouse is connected, most often its not seen by the user. This allows the user to see the mouse when connected through Parsec

PARSEC →

  • Install Parsec on both host machine and VM and sign in to the same account
  • From host machine try to connect to your VM
    NOTE: If you want to connect to Parsec on VM Boot ensure you select “Per Computer” while installing Parsec instead of “Per User”
  • Launch USBIPD.exe and type the IP Address of your host machine. (Open CMD and type ‘ipconfig’ and select the IP of your ethernet or wifi adapter)
  • Click connect and the mouse should show up
  • Attach the mouse
  • Your mouse should be working in Parsec but not in Host machine

TROUBLESHOOTING

  • If your mouse does not show on USBIPD on your VM here are a few things to keep in mind
    • IPv4 Must be disabled on your main Realtek ethernet driver on host computer and enable on your network switch for your VM
    • If something does not work you can try these steps:
      • Disable Network Switch for VM
      • Disable Main Network adapter for PC
      • Disable IPv4 for Main Network Adapter

EVERYTHING IS NOW DONE, YOU CAN INSTALL AND PLAY YOUR GAMES ON YOUR VM

LEAGUE OF LEGENDS SPECIFIC

  • In order to play league and bypass Vanguard completely all you need is a small script which runs while you have league running
  • All this script does is the moment League of Legends.exe is launched, which is the actual game .exe, it quits out of it → Restarts Vanguard Service → Relaunch the Client
  • Copy the script below and type it in a text document
  • save text document as auto-restart-vanguard.ps1
  • Launch this whenever you want to play league of legends and its done
