It doesn’t have to be 1:1. Make sure to install drivers, set up proton (so that proton is used by default), Install Only Office (because it is the most appealing to Microsoft office user) and if she really needs it create web apps for Microssoft Office and ensure that they can be launched from the desktop, taskbar, and start menu. Also Install adblockers and whatnot on her browser. Just nothing that could interfere with her workflow. So Ublock, Sponsorblock, CleanURL, I Don’t Care About Cookies, and Return Dislikes to Youtube. Also use this hardening script because it makes Firefox secureoit of the box and in my experience has never gotten in my way: github.com/hnhx/user.js
