OS question (Upcoming)

[DkDark]

Budget (including currency): $3k

Country: USA

Games, programs or workloads that it will be used for: gaming

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

So one comment I am seeing fairly often, especially on Reddit, is "Imagine buying/paying for Windows"

My plan was to of course purchase Windows 11 for $110, the price it is listed for. 

Now I would siphon or use the Windows from my current laptop had it not been an OEM license (or at least I think it is).

So besides buying Windows at full price, or buying those "keys" for $10 which are actually only valid for 60-180 days and have a watermark, what other means are there for getting the full legit version of Windows 11? I'd like to say I'd be saving myself the $110 should there be another way but I'm more than happy to spend it if it means having no quirks when it comes to getting my OS installed on my new build.

Thanks
