Win10 Home & Pro will get the 2nd, optional monthly updates until June 26, 2024, with the End of Support October 8, 2024.
Enterprise & EDU versions will get updates until October 14, 2025, so one option is to install the Enterprise version over the top of a current Win10 installation to get one more year of support. It will not be activated but Win10 will still work. Joining the Insider program, which basically just requires registering with an email address, allows you to log into the Insider web site & download Windows insider ISO files, which is the way I get Enterprise version ISOs. Microsoft will offer paid extended servicing, and like with Win7, someone(s) may develop and release a hack that allows you to receive those updates.
I've got a tablet with 32-bit UEFI BIOS and zero Linux support so it's stuck on Win10 -- I've got the Ent. ISO handy while I wait to see if a hack appears before November, 2024. Everything else will be moved to Win11, starting once Microsoft releases the 24H2 RTM ISO. One of the easiest workarounds to install Win11 is to use Rufus with the ISO -- it can do the mod for you while copying everything to a USB stick -- but there's loads of info online if you want to take a full DIY approach.
