Yeah, it's tough switching over but worth it IMO. It cuts twice as deep when you build a custom PC, buy a legitimate copy of windows full price just for stuff like this to happen. I even paid twice because I built my mother a pc.
Surprisingly she asked me to switch her over to Linux after seeing me play games on it. She would always call me up Everytime Microsoft popped up a full screen and trying to sell office 365 and getting her to agree to new privacy settings.
Almost everything she does is online, email, personal accounting in a spreadsheet, using the printer, and some gaming. The hardest part for her was relearning the small stuff like scanning documents and learning which one was her email app. It runs the sims 4 and an ancient game called wizards101 just fine.
The funny thing is I warned her it's not a smooth transition verified multiple times before switching and encouraged her try it on her laptop for about a week or so before switching her main computer. She went through with it though and started to really love it once she figured out the main stuff.
The way Apple wants you to transfer files is to install iTunes from the Microsoft store. I do not envy the fact that you have to use an app that hasn't changed much since 2014. Or the Finder on macOS.
