Gamepass isn’t for me, but dual booting for it is understandable. But office? I’ve found LibreOffice and OnlyOffice are usually “good enough,” and if you really need true MS Office, I believe they offer web editors now
The web editor isn’t nearly as good as their desktop app counterpart. LibreOffice is fine for basic usage, but Excel is still king if you’re using any kind of advanced feature.
I know you probably mean newer Xbox games, but check out xemu if you like retro titles.
