Delete Yosemite? Find Mountain Lion? Post-Stroke Explanations, Please

I hope you can help me. I had modest tech abilities until 6 months ago, when I had a stroke. I don't know now what these abbreviations mean. I have read the answers but they don't seem to apply.

My mini got a new hard drive last November with Mountain Lion installed. I think I wanted to upgrade to Mavericks but somehow got Yosemite instead, which is awful and messes with everything. Can I get rid of it without losing everything? I don't have anymore an external hard drive, or something else I can't recall. Thank you.

Late 2012 iMac not seeing Bootcamp 6 update

I would like to install Windows 10 and use Bootcamp 6 to do so on a 2012 iMac. According to Apple's documentation, this should have appeared and been installed by software update. When I check my Bootcamp version though, it is 5.1.4. I have updated everything on the actual computer (10.10.5, etc).

They used to provide access to the direct PKG files to install, but I don't see one for bootcamp 6.

What am I doing wrong. According to their support document, this machine should be supported - https://support.apple.com/en-us/HT204990

How do I open Apple Maps from a Google Maps link in Safari?

I would ideally like a bookmarklet since then I could use it on iOS as well. I tried this Safari extension but I would like an option in the toolbar to open Apple Maps when I'm already on a Google Maps page instead of directly opening Apple Maps form a Google maps link.
