I've steadily moved away from windows products.
Windows media center is hot garbage compared to virtually anything, Microsoft Office is pretty awful and easily supplanted by its free competitors, and for reasons I'll never comprehend, Windows photo viewer can't GIFs (you had one job!)
I use libre office a lot, but interoperability can be a chore. I have to submit online assignments, and sometimes the formatting will get all futzed up when a libre file is opened by its corresponding MS program. ><
