I'm not very Windows literate these days. Am I right in thinking that Windows doesn't include the ability to open .7z files by default, so you need extra software? What extra software do people generally use for that?

Do Windows users generally know which out of the x86 and amd64 options they should pick? If people aren't sure, is there a command I can suggest they run or a program they can look in to figure out which one they should use?

(Earlier on I was trying to do this in a GitHub Actions workflow and I wasn't sure how to tell if it was x86 or amd64)

@simon Many people won’t know off the top of their head, but vanishingly few users will be on 32-bit. Think you can safely recommend amd64 to most people.

@simon Honestly despite being a techy person and now a programmer, I've never been good knowing what download option to pick. Doesn't help you need to know if your system is 32 or 64 to choose between 86 and 64 🙄

These days most windows are 64 bit though, so unless your target audience is "people/businesses with very old machines" just heavily recommended the 64 (and have a clear error installer for people who need the 32!)

@simon Yes. Because it’s a trick question. There really aren’t enough AMD64 architecture Windows devices in the marketplace for it ever to be the right option. And while people like you and I are chatting about it here, most people aren’t getting software off of git. We are the corner case of this thought experiment.

@simon pretty much all modern computers are amd64 - x86 is provided as legacy version, and will still work, but not benefit from modern cpu power.

@simon i think that’s now included in win11

@simon 7zip has long been my alternative

@simon Since 2023, Windows 11 has included native support for 7-zip, rar, gz, and anything else supported by libarchive: blogs.windows.com/windowsdevel

I expect people would install 7-zip (or a spyware clone) to get that support if they're on an older build of Windows.
