I'm a new ASUS customer and Portatech is doing my build for me with the Ryzen 7 2700X CPU and Asus ROG Strix X470-F Gaming Motherboard. My question is that I have the original build of Windows 10 Home (32/64bit version) on a USB 3 flash drive that I bought from a physical Best Buy store here in New York back in 2016. I had never used it and it just sat there until I decided to get a new build. It has the Certificate of Authenticity on the box and inside there's the Booklet and the Key and the USB 3 flash drive, the only thing is it's labeled "Puerto Rico" on the box but it also says English, so should this early build of Windows 10 Home work fine on my system and once I install it on my Samsung 970 EVO NVMe drive I can just go to the MS website and download the latest build? I called MS and they told me it should work but I wanted to make sure, or else I could just have Portatech install the latest build and pay an extra 100. But then the version I bought back in 2016 for 120 would have been wasted. MS also told me that as an alternative I could download the latest build of Win 10 Home on my laptop and save it to a newly formatted SD disk and run it on my new build. What should I do? I'm leaning towards just using my early version of Win 10 Home and updating to the latest build after it's installed and thereby saving $100 and not wasting the Win 10 Home I bought in 2016 for $120. Portatech told me that either way my build will be fully tested for stability, compatibility and temps and will be fully burned in. What should I do? Thanks!
