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.
Υou can download the Windows iso, burn it in a usb stick before you nuke it to install linux, and find free legal serial numbers online (there are various serials for all versions of win10/11, all legal – it’s considered semi-activated with these).
If the device ran Windows before the key is stored in hardware
This is very very important unless you have another windows computer around. Took me a whole day to figure out how to properly burn a windows install USB from linux. It isn’t straightforward.
There’s a very good chance the key is stored in the EFI, making this the absolute easiest part. I’d just make sure to get the Windows installer on a USB stick before installing Linux, if there aren’t any other Windows machines around. And also make sure I have a wifi/ethernet driver available before reinstalling Windows, if it comes to that. It can be tricky to install Windows without network, these days, and even if you get past that (which I’d recommend, to bypass a Microsoft account), you still need it once you’re in the installed OS.
