Mining Rig Setup -- Problem with OEM Windows 10 Pro I bought off ebay

[leowonderful]

Every time I build a computer, mining rig and just any computer in general, I use OEM codes and they have always worked. eBay is extremely buyer-sided so you can either ask for a replacement or refund and you should be set. I’ve seen codes for Windows 7/8/10 go for sub-$10 and even $5 commonly, not sure if that’s changed or not recently.

The most important part is that eBay is buyer-sided. Even if the seller states no returns you can still return a product most of the time and still get a refund. Just don’t fuck people over with it by requesting a return or refund for a genuine, working product. Big reason why I never sell on eBay.

Thanks for all the help guys.

I re-installed windows on a fresh SSD from a thumb drive I generated from microsoft.com today.   So I know I got a clean malware free distribution of Windows 10 64 bit on thumb drive.  

I used the COA I got (in sealed package) and had the same problem with activation -- said the key was already in use.

So I called Microsoft and well it was a pretty easy process to get them to activate that COA key.

All is working good now

$47 is a lot better than $199!  Thank goodness.

Gonna buy one or two more copies at $47.. one for alternate SSD for rig test bed and another for offline encrypted wallet.   Unless Ubunutu or the like would be good for offline wallet.. do all the wallets work on linux or should I stick with windows for offline wallet?  (Basically my personal use computer has a 4 bay removable SSD thing.  I just pull out the SSD I don't want to run and push in the one I want to run.

How about a thumb drive with a live copy of linux on it for my hardware wallet?  It'd be like $10 and I could back it up to another $10 thumb drive.. keep one in the safety deposit box along with any paper wallets / seeds.

(I guess eventually I'd want a Ledger Nano S, whenever they become available again.)

The Windows 10 Pro seller has a 99+% rating on ebay.  Sold like 436 of these WIndows 10 Pro OEM disks with COA.  I looked at the feedback for the seller and tons of positive comments regarding the product I was interested in.  SO that's why I bought it.

I am installing WIndows 10 64 bit from a USB thumb drive.  I downloaded the image from microsoft and made the thumb drive using their tool.  I made sure I selected 64 bit and what I purchased from ebay was in fact 64 bit as well.

I'll see how it goes.. I'll try calling it in.  The seller emailed me back and told me to call a number and try other things, and interestingly gave me another product key to use.. although I think I'd want a physical copy of COA sticker in case I'd ever want to resale this.

chances are considering its OEM, there are versions of windows that are one time use with one motherboard, if you got one of those you cant resell it cause it wont work with another mobo, just thought I should put that out there, OEM windows usually comes with a full computer system and there used by those whom build computers and sell them brand new, they don't come with disc's at all its just a key, newegg sells the OEM version and the retail version

Absolute majority of it are fake; there could be few genuine from time to time, otherwise it's like with quality japanese caps (and pretty much everything!!): if it comes from China, it's fake. I have 3 theories, most likely all of them are valid and it depends who do you run into:

- they take the keys from gazillion of PCs which go there as scrap from Europe and Americas and print new stickers with them
- they found the algorithm and created a key generator and print new stickers with new keys
- they steal keys via malware from PC registry and print new stickers with them

You can buy OEM windows keys from websites directly. No need for ebay. And they will even give you a second key if the one you bought doesn't work. I ve done this to both my main PC and my mining rig.

Google it and you ll find the site that sells these. Im not posting in case its not allowed or something. but if its ok ask the mods and i will share.
