At first I thought, Windows SE meant Single Edition
but I was thinking of Single Language edition where windows is installed for just one Language, (Hindi, Chinese, etc)
Most new laptops are sold with Windows running in S-mode
as
@Cyler has stated above, users cannot install apps that are non-Microsoft verified apps
If this was a personal use laptop, one can just switch out of S-mode to install these blocked apps
otherwise, one would need to ask help from the IT Department for installing these apps
