Change Office Edition

This option is available in the MAS script. You can use this for Office C2R (Ver 16.0.9029.2167 and later) to change, add and remove editions along with an option to change the Office update channel.

How does it work?

Office C2R (Click To Run) installation files are unified, meaning that whether you install a single app like Word 2021 or a full package like ProPlus2021, both will download almost the same size of files.

C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeClickToRun.exe

This program allows us to add and remove Office editions, and since installation files are unified and they are already installed, and it uses delta updates, it can add new editions and apps to the Office with very minimum Internet consumption.

Change Office update channel

The same script also offers an option to change the Office update channel.

VL (LTSC) channel limitations

(Applicable to 2019/21/24 VL)

Officially, the update channel can not be changed to/from the VL (LTSC) channel to/from any other channel.
So if the Office installation file or installed channel is from the VL (LTSC) channel, then only that channel will appear in the script
also if your update channel is not from the LTSC channel, then the script won't Offer you the option to change the channel to LTSC.

Windows 7/8/8.1 limitations

Office C2R is officially not supported on Windows 7 / 8 / 8.1 anymore.
The last available build is fixed on certain builds and won't get any updates. VL (LTSC) channels are not supported on these Windows versions so they won't appear in the script.
