Windows 10 collects what they collect so they can figure out what areas need some love and what to focus on.

Google collects the same stuff and more to deliver advertising content and to sell to third parties.

I'd rather let windows do what they want & block google but since that's not an option, I don't actually care that MS knows that I prefer libreoffice over ms office.

You always have bottlenecks. There's no such thing as no bottleneck unless you've spent thousands of hours analyzing performance & your usage.
 
 
Here's how you find your bottlenecks: Run whatever you use your computer for most, open up task manager, and see if any of the numbers in the process tab are turning yellow.
