Not just an Universal MediaCreationTool wrapper script with ingenious support for business editions,
A powerful yet simple windows 10 / 11 deployment automation tool as well!

Windows 11

Script creates media that will automatically skip upgrade or clean install checks
Sharpest bypass I came up with is using /Product Server option or <INSTALLATIONTYPE>Server on the install image,
tho I understand that many of you dislike the Installing Windows Server cosmetic artefact (not purely cosmetic),
so the methods used are my originals Appraiser_Data.ini trick to upgrade plus winsetup.dll patching in boot.wim.

Check out the bypass11 folder for alternatives / standalone scripts [pending]
Quick_11_iso_esd_wim_TPM_toggle.bat
usable with any downloaded windows 11 iso or extracted esd and wim
right-click file - SendTo - select script to toggle bypass on or off (kickass feature: it restores iso to original hash)
business / enterprise media is best since it comes with ei.cfg so setup won't ask for a key at start
tho you can add a generic ei.cfg to the media\sources yourself:
[Channel]
_Default

Skip_TPM_Check_on_Dynamic_Update v4 and older v3, v2, v1
will bypass windows 11 setup that was run manually under windows, or via windows update
bypass getting 11 after OfflineInsiderEnroll to Beta or Dev channels and doing an update check

Windows 10

Script works just as well as before, not having to deal with microsoft's latest anti-consumer practices..

Presets

1 Auto Upgrade with detected media, script assists setupprep for upgrading directly
- can keep files and apps on mor scenarios such as cross-edition setups - can troubleshoot upgrade failing by adding no_update to script name

2 Make ISO with detected media in Downloads folder directly
- can override detected media by adding edition name / language / arch to script name

3 Make USB with detected media in specified usb target
- can click Back and select ISO instead to save in a different path

4 Select with picked Edition, Language, Arch - on specified target
- implicit choice, will include setup override files

5 MCT Defaults with GUI selected media, makes vanilla, default MCT iso/usb
- no added files, script passes products.xml and quits without touching media

1-4 presets will add any setup override files to created media
- can be disabled by adding def to script name
- write $OEM$ folder (if it exists) with post setup tweaks like $OEM$\$$\Setup\Scripts\setupcomplete.cmd
- write sources\PID.txt to preselect edition at media boot or setup within windows (if configured)
- write auto.cmd to re-run upgrade with cross-edition support from media on demand
- write AutoUnattend.xml in boot.wim to enable local account on Windows 11 Home
- patch winsetup.dll in boot.wim to remove windows 11 setup cock-blocks when booting from media

configure via set vars, commandline parameters or rename script like iso 21H2 Pro MediaCreationTool.bat
recommended windows setup options with the least amount of issues on upgrades set via auto.cmd
awesome dialogs with keyboard focus to pick target version and preset action

No need to right-click Run as Admin, script will ask itself. Saving the Raw file no longer breaks line endings
We did it! We broke the previous gist ;) So this is the new home. Thank you all!
