[Windows 11] persona78:
Hi!

There are a simple powershell/Hybrid script that will allow you to install Windows 11 without any conflicts.

The script creator is AveYo, it dynamically skips the anti-consumer windows 11 setup checks via /Product Server trick it is most reliable, and only has a 'Windows Server' label cosmetic-ish difference, works with:

Setup via Windows Update (after using OfflineInsiderEnroll by whatever127 and abbodi1406)​

Setup via mounted iso / usb (use the Quick.. script for skipping 11 setup checks at boot)​

Im using in my old PCs and it works fine.

Note: If you do a fresh install from 0 you will need to run script again to windows update work properly.

This is the script, save as bat:

@(set "0=%~f0"^)#) & powershell -nop -c iex([io.file]::ReadAllText($env:0)) & exit/b
#:: double-click to run or just copy-paste into powershell - it's a standalone hybrid script

#:: v7 dynamically skips the anti-consumer windows 11 setup checks via /Product Server trick
#:: it is most reliable, and only has a 'Windows Server' label cosmetic-ish difference
