I’m considering switching to linux but I’m not a computer savvy person, so I wanted to have the option to switch back to windows if unforeseen complications (I only have 1 pc). Is it just a download on usb and install? And what ways can I get the product key or “cleaner” debloated versions.
Just run Linux straight off the installation media in what’s usually called something similar to a “live environment” until you’re sure it works.
Otherwise, installing Windows is somewhat more difficult than installing an “easy” Linux distro (e.g. Mint) because you’ll have to deal with “activation” bullshit and updated/manufacturer-provided drivers. Unless your computer comes with a computer-specific recovery disk or recovery partition (that you didn’t delete when installing Linux), in which case it’s easier.
