Linux is open-source, and you can install it for free, unlike Windows, which comes at a rather hefty price 'For One Computer'.
With Linux you can duplicate the hard drive an put it in another computer and it will find all the hardware, even if different and just work. A spare duplicated hard drive is the ultimate backup of a computer system.

Yep, and once you make that installation stick, you can use that same stick to install to as many boxes as you like.
Unless you are on the retail channel, in which case if you can you have a Windows 10 Retail license, you can transfer it to another computer, as long as you deactivate the old device. There is no limit on hardware. And how is here.
Years ago, the Lord enabled me to purchase a Win/ 8 upgrade from XP for $29 with the rebate (took months!) and then 8.1 was a free upgrade, and then I transferred it to a new homebuilt and installed W/10 on it (free download from MS) and since either XP or the upgrade was retail then I just needed to (prayerfully!) get on the phone with MS and find the license key and activate it. Now I may upgrade to W/11. Thank God for good deals for be used for good.
