Activate Windows

First install vlmcsd and OpenVPN's tap driver for a tunnel, as Windows will refuse to authenticate against a KMS server running on localhost

choco install -y tapwindows
# Download the vlmcsd binaries archive and extract binaries/binaries/Windows/intel/vlmcsd-Windows-x64.exe to C:\install\vlmcsd.exe
New-Item -ItemType Directory -Force -Path C:\install
Invoke-WebRequest -Uri -OutFile C:\install\vlmcsd.exe
# Install the service
C:\install\vlmcsd.exe -s -U /n -O .
netsh advfirewall firewall add rule name="vlmcsd" dir=in action=allow program=C:\install\vlmcsd.exe enable=yes
# Start the service (it's enabled, reboot would also start it)
net start vlmcsd
# If you do not have Home(Core) installed, you can switch between different editions (not Home)
# You can get a popup with available editions via 'slmgr /dlv all'. 
# Get just the editions by copypasting the box and running 'grep Name boxtext.txt | sort | uniq'
# Note: Windows 11 KMS keys seem to match W10 ones

# Switch edition to Edu
Cscript.exe c:\windows\system32\slmgr.vbs /ipk NW6C2-QMPVW-D7KKK-3GKT6-VCFB2

# W11 Edu 
slmgr /ipk NW6C2-QMPVW-D7KKK-3GKT6-VCFB2
# Set KMS server to a LAN one
#slmgr /skms
slmgr /skms
# Force activation now
slmgr /ato
# You should get a box in a few seconds that the activation passed. You can see the license info with
slmgr /dli

Activate Office

# Convert Retail to VL first if Office is Retail

cd 'C:\Program Files\Microsoft Office\Office16'
# Office 2019 Pro Plus
#cscript ospp.vbs /inpkey:NMMKJ-6RK4F-KMJVX-8D9MJ-6MWKP
# Office 2021 Pro Plus
cscript ospp.vbs /inpkey:FXYTK-NJJ8C-GB6DW-3DYQT-6F7TH
cscript ospp.vbs /sethst:
cscript ospp.vbs /act

Force W10 to W11 upgrade

# Source for some of these:
# Can also be done by doing SHIFT+F10 from an unmodified booted W11 installer -> regedit and adding the LabConfig values

## Upgrade W10 to W11 with at least TPM 1.2
# Ignore CPU freshness check and downgrade minimum TPM version from 2.0 to 1.2 for upgrades
reg add HKLM\SYSTEM\Setup\MoSetup /v AllowUpgradesWithUnsupportedTPMOrCPU /t REG_DWORD /d 1 /f

## Clean install W11 with possibly no TPM, <4GB RAM and on BIOS/UEFI with no Secure Boot
# Bypass TPM check in booted image
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassTPMCheck /t REG_DWORD /d 1 /f
# Bypass 4GB+ RAM check in booted image
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassRAMCheck /t REG_DWORD /d 1 /f
# Bypass SecureBoot check (UEFI check pretty much) in booted image
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassSecureBootCheck /t REG_DWORD /d 1 /f
# Bypass Storage Check... is this even required?
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassStorageCheck /t REG_DWORD /d 1 /f


You can download .ISO of Windows 10 or Windows 11 versions directly from Microsoft's servers. Note that you'll have to spoof the user agent if you're on Windows, as you'll get redirected to the Media creator tool otherwise.

The ISOs provided by MS contain all the editions (sans enterprise pretty much), but you might have to add.../sources/ei.cfg file to show them all.

You can download older versions of windows and different versions of W10 through this method

If you want Enterprise, one way to get it is to install Pro/Edu and then switch the license, as per the powershell example above.

Reboot into UEFI

Open admin cmd.exe and run:

shutdown /r /fw /t 0

Windows 11 Installation

[[Creating a bootable flashdrive|Boot from the flash drive]]. Remember to always select "Custom" where applicable. You can skip creating a Microsoft account by trying to login with a nonexistent email.

Windows usually gets all the drivers itself, but if something doesn't work as it should you might need to visit your motherboard or device manufacturer's website and download drivers/update firmware.

Windows usually downloads an outdated GPU driver so head over to AMD's or Nvidia's website depending on what GPU you have.

If you already have or had a Windows license, then your hardware ID combination(should be motherboard+CPU) is stored on Microsoft's servers and your license will be obtained automatically when you connect to the internet, provided you installed the same Windows version.

If you don't have a W11 license you can either:

  1. Buy a license key from official source. Buying from unofficial sources/grey markets is exactly as illegal as cracking it. You'd be literally giving your money away to thieves. The keys are from hacked MSDN accounts, credit card frauds etc.

  2. If you're in college or some sort of academic institute, they might have MSDN licenses, see if you can find a copy from their IT department.

  3. Not activate Windows - you will not be able to use Personalization features and it'll nag you

  4. Activate Windows with KMSpico. Defender will complain about it, allow it manually in Defender after installing it. Alternatively you can use vlmcsd if you want an open source, more hardcore solution.

Upgrade from Home edition

Use a generic key - W10 or W11 - to upgrade to the needed edition.

# W10/W11 Edu
changepk.exe /ProductKey YNMGQ-8RYV3-4PGQ3-C8XTP-7CFBY

This is not a valid key for activation, it only allows for the upgrade.

Setting up OpenSSH

Due to this, to connect to an admin user, one needs to use


instead of

$PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'
echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIPR3/QA/+Kq1txg/APGQcpa3UradYnaaxSomDQamFDpH' > 'C:\ProgramData\ssh\administrators_authorized_keys'
# Check that the resulting file is(file is not preinstalled):
#   Unicode text, UTF-8 (with BOM) text, with CRLF line terminators
# And not this or anything else:
#   Unicode text, UTF-16, little-endian text, with CRLF line terminators
file 'C:\ProgramData\ssh\administrators_authorized_keys'

To use sshd, first install it via Optional Features as per the docs;

To start it, run services.msc and configure OpenSSH Server to start Automatic and also Start it.

Disable password authentication in the config and then restart the server to apply it. Optionally also disable forcing the key path for admins.


If you can't connect to an admin account and you kept the forced key path, permissions are probably wrong, run the following to set them correctly

icacls C:\ProgramData\ssh\administrators_authorized_keys /remove "NT AUTHORITY\Authenticated Users"
icacls C:\ProgramData\ssh\administrators_authorized_keys /inheritance:r
get-acl C:\ProgramData\ssh\ssh_host_dsa_key | set-acl C:\ProgramData\ssh\administrators_authorized_keys

Install spice-guest-tools on KVM with Spice for better experience.
