Back in the day when i had a windows laptop for work you could just download the windows binary distribution of emacs and run that, has something changed?
However, I believe Microsoft Intune is used within the Business to control what software can and cannot be installed. So my guess is Windows won't allow you to install via a typical .exe
I am not suggesting the above is 100% valid. I just don't want to get a new laptop and find out. Maybe I can still use Emacs via WSL... bypassing Intune????
At the end of the day, I understand Security is getting much more serious in recent years - and we even have a dedicated department - but controlling the software to install is crazy, especially for a development team.
(I don't have any experience with Intune so pardon my ignorance.)
Presumably performance matters above all else (although it likely doesn't in such a place). If Emacs actually makes a meaningful difference, then just use it to do your work more efficiently.
You can run a batch/shell script, right? Of course you can. Would you ask for permission to write and run a script? If not (and presumably you wouldn't because that would be silly) then you shouldn't ask to run Emacs. You "own" both and take on all the "risk". There's really no difference.
But really, truly ask yourself, is whatever cause you're working towards (that is, the mission of the company) worth sacrificing your dignity for?
