I have not tried this yet but it should work on any OEM system that has an SLIC 2.1 or later.

This works only if the motherboard was previously activated under win7 or win8. A few years back Microsoft made it possible to activate win10 by using the original win 7 or win 8 product key. I have bought 1 used HP and 2 used Dell motherboards and installed Win7 and upgraded to 10 at no cost other than the hardware. It helps to know if the bios supports vista (SLIC 2) or win7 (SLIC 2.1) as it is currently (Jan 2019) still possible to upgrade 7 to windows 10 (thanks Microsoft!) at no cost from any activated win7 system (but not from vista). You can buy the DVD and the key from anyone on eBay or you can simply google for the key and the ISO image. One can obtain (for example) the Dell DVD with vista or win7 and install it on your used Dell motherboard and activate it using the corresponding Dell key. OEM motherboards (Dell, HP, etc have OEM license and their bios's contains a table (SLIC) of license information. Most likely, the seller will get shut down relatively soon and these keys may get deactivated, and the seller will just move on to their other alternate accounts to sell more.įrom what I understand, the windows license goes with the motherboard. So, these people who gave positive reviews to this seller have only had their keys for a matter of weeks at most.

It's also very possible that the initial reviews might have been from alternate accounts of the same user. However, if we check their feedback page, we see that.ġ) They only signed up for the account only 3 months ago.Ģ) Out of the 149 ratings, nearly all of them were received within the last month. Looking at feedback, the seller has 100% with 149 positive ratings. For example, I did a quick search and checked the first listing for a $10 Windows 10 Professional key that I saw. Have a look into their feedback to see how long they have been selling the keys for. Could it be Volume discounted for Companies keys ? and if not legal how come They Stay 100% positive rating and not banned ? some of them sold 300 keys and no one reported them to ebay.
