I upgraded from 8 to 8.1 using an ISO image, and since it doesn't accept 8.0 keys (WTF?) I used the KMS Client Setup key that ends with 9D6T9, taken from a Microsoft article (jj612867). After install, activation with the original v8 key (which is Core, and probably OEM) doesn't work, my guess is that this is because the install is "Pro". Is there a way, without reinstalling, to change Pro to Core, or make it accept the Core key another way?
Thanks s1ave. That looks like a reinstall, practically? The 8.1 "update" already ruined half my software and settings, I shudder to think what would happen after another round. Paul, it's a public KMS client setup key.
I changed it to "censor" the Microsoft setup key. I can't say I see why, since this key is public, and it's already posted, along with other similar keys, in many threads in the forum.
the forum owner made the rules and since there were several DMCA takedown notices in the past, he does not want to display keys. I told you not to ask
I share the same misunderstanding with the keys as you bought a lenovo that came with win 8 Core SL OEM.. I cleaned it all! I installed win 8.1 w\update pro, and, obviously, I cant activate it using the OEM key I've saved. Now I'm looking for a Core SL iso there Isn't a way to convert the Pro iso to Core SL iso before install it?
I don't think the ISO is the problem. I used the "multiple versions" ISO, which should be both Core and Pro. It's just the key. There's a Core setup key you could try, search for "windows 8.1 core setup key".
Are Core/CoreSL keys not compatible? What's single language anyway, restrictions on the language options?
Nope, keys are not interchangeable. These versions are intended for so called emerging markets and don't allow to change the language of the running system.
Microsoft really should simplify their stuff, if nothing else at least far less install media variants.
Hmm, for the average users there are only 3 ISOs, most will use the Core/Pro Retail one and some need CoreSingleLanguage, CoreCountrySpecific should even be more seldom. Pro_VL, Enterprise and Servers are mostly used in corporate environments, universities and by geeks.
Don't forget everything with N and without, and silly things like a separate version for British/American (can't they include all languages? Shouldn't take much space).
