Microsoft offers a tool on its website called Media Creation Tool, or MCT for short, which has a lot of features: it can be used to download Windows 10/11 system image ISOs, and it can create bootable USB disks. This tool is very easy to use, basically follow the prompts all the way to the next step.

Today provides another AveYo script , based on the MCT tool , enhanced its functionality , making it easier to operate , the following is a brief introduction to this open source project :

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!
If you had no success launching the script so far, this latest version will work


Auto Upgrade with detected media, script assists setupprep for upgrading directly

- can keep files and apps on more scenarios where os and target edition does not match
- can switch detected edition by adding EditionID to script name
- can troubleshoot upgrade failing by adding no_update to script name
- auto defaults to 11, so pass version as well for 10: auto 21H2 MediaCreationTool.bat

Auto ISO with detected media in current folder directly (or C:\ESD if run from zip)

- can override detected media by adding edition name / language / arch to script name
- example: 21H1 Education en-US x86 iso MediaCreationTool.bat

Auto USB with detected media in specified usb target

- for data safety, this is not fully automated - must select the usb drive manually in GUI

Select with user picked Edition, Language, Arch (x86,x64,both) - on specified target

- implicit choice, includes setup override files (disable by adding def to script name)

MCT Defaults runs unassisted, creating media without script modification

- no added files, script passes products.xml to MCT and quits without touching media

1-4 presets will modify created media in the following ways:

- write auto.cmd to run on demand for auto upgrade with edition switch and skip tpm
- write $ISO$ folder content (if it exists) at the root of the media
if you previously used $OEM$ content, must now place it in $ISO$\sources\$OEM$\
- write sources\PID.txt to preselect edition at media boot or within windows (if configured)
- write sources\EI.cfg to prevent product key prompt on Windows 11 consumer media (11 only)
- write AutoUnattend.xml in boot.wim to enable local account on Windows 11 Home (11 only)
- patch winsetup.dll in boot.wim to remove windows 11 setup checks when booting from media (11 only)
- can disable by adding def to script name for a default, untouched MCT media

Simple deployment

auto.cmd is behind Auto Upgrade preset via GUI
Can run it fully unnatended by renaming script with auto MediaCreationTool.bat
Makes it easy to upgrade keeping files and apps when the OS edition does not match the media
Should allow upgrade from Ultimate, PosReady, Embedded, LTSC or Enterprise Eval as well

Generated script is added to the created media so you can run it again at any time
It is fairly generic - it will detect available editions in install.esd, pick a suitable index,
then set EditionID in the registry to match; can even force another edition, keeping files and apps!
On 11, it will try to skip setup checks (can disable this behavior with script var)
Finally, it sets recommended setup options with least amount of issues on upgrades

Let's say the current OS is Enterprise LTSC 2019, and you use the business media to upgrade:
auto.cmd selects Enterprise index and adjust EditionID to Enterprise in the registry (backed up as EditionID_undo)
Maybe you also want to switch edition,
ex. by renaming the script to ProfessionalWorkstation MediaCreationTool.bat:
auto.cmd selects Professional index and sets EditionID to ProfessionalWorkstation in the registry.

Let's say the OS is Windows 7 Ultimate or PosReady, and you use the consumer media to upgrade:
auto.cmd selects Professional index, and sets EditionID to Professional or Enterprise, respectively.
In all cases, the script tries to pick an existing index, else a compatible one to keep files and apps on upgrade.

Let's say you have a dozen PCs spread with versions: 7, 8.1, 10 and editions: Ultimate, Home, Enterprise LTSB..
If you need to upgrade all to the latest 10 version and only use Pro, you could rename the script as:
auto 21H2 Pro MediaCreationTool.bat

Can even add a VL / MAK / retail product key in the same way to take care of licensing differences.
The script also picks up any $ISO$ folder in the current location - for OEM branding, configuration, tweaks etc.


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