For the technically-minded Linux is an option, but for everyone else Windows at least allows you to firewall off any domain you choose. Sure, you'll probably break Windows Update in some way, but the Windows kernel doesn't try to bypass your settings (yet).
I can't tell if you being extremely sarcastic or lack experience running both of these OS's...
They got used to the system quickly and used it for 4 years, until the OS went out of LTS and I told them not to use it anymore… but still, they have no idea what a terminal is, no tech savvy, but still used it for their basic use-case for 4 straight years without issue! I didn’t even have to help them after the initial install. Couldn’t have been easier.
If you're medium tech savvy then you run the risk of knowing how to break something but not fix it.
My Windows 10 install may be full of spyware I need to block, but the software works pretty flawlessly in comparison.
With the terrible state of Nvidia's drivers, my Linux install has kernel panicked more often than my Windows box has BSOD'd.
Reliability-wise, desktop Linux is boringly stable these days as long as you don't insist on the bleeding edge by using Arch or Debian unstable.
The MS Office situation has gotten much better with the rise of online office suite web apps, including Office 365, as well as professional desktop software like SoftMaker's closed-sourced and misnomered FreeOffice[1] that has great compatibility with files written in MS Office's formats.
Lack of Photoshop is a problem, but if you're doing animation, special effects or video editing work, Linux has you covered because companies release Linux versions of their workstation software like DaVinci Resolve, Houdini, Autodesk Flame, Blender, Lightworks etc.
