Windows 10: Upgrade W10 Edition with W7 key, possible?

Hello, I was sure I would be able to use W7 Pro OEM key I have spare to upgrade my W10 Home to Pro (preinstalled OEM OA), but when I try to change product key in Settings> Updates> Activation, the W7 key is refused with 0x004f210 error. Did I misunderstood the process or is something wrong with the key itself..?

:)

 

Retail key comes up as invalid when trying to upgrade win 7 to win 10

You have to upgrade from W7 to W10 in order to (automatically) activate the later.

Once W10 is activated, you can do a fresh W10 install (don't give any key). But not before !

W7 key won't work for W10 !

Hi!

I have been following a this thread: How to active win 10 upgrade?

I tried the produkey on several of my upgraded machines. I have a W10 pro OEM DSP purchased for a hard drive, built the machine. Same machine I have a hard drive that had W7 Pre OEM DSP. Upgraded to W10 Home. The W10 Pro retuned the same key as the COA.
W7-W10 retuned a different key then the W7 COA. I have a W7-W10 HP laptop that also returned a different key then the W7 COA.

So if the product key is stored in the bios, (sure like to know what chip) does the W10 install/upgrade, flash the chip?

 

Go to activation menu - click on link "go to store".

This takes you to pro purchase menu.

Under the buy pro 10 button is a link "I have a Pro 10 key".

Click on that and enter 7 Pro key.

 

Hello, this is the same as described, I tried both. I actually thought it's the same thing.

 

See if this link helps https://support.microsoft.com/en-us/...0-why-activate

Or you could try this

• Press “Windows key + R” to get the run window.
  
• Type “slui 4” and press enter.
  
• Select your 'Country' from the list.
  
• Choose the 'Phone Activation' option.
  
• Stay on the phone (do not select/press any options) and wait for a person to help you with activation.
  
• Explain your problem clearly to the support person.
  
• Follow the on screen directions to activate over phone.

 

OK, that's good idea, I will try phone activation. So basically, what I am trying to achieve should work, right?

 

Read OP post again.

The issue is not activation.

The issue is he is trying to upgrade to PRO from Home!

 

No 100% - it will not work. You have to upgrade to Pro.

What version of 10 home do you have installed 10240 or 10586 (run winver).

You need to upgrade to 10586 to use 7 key.

In answer to other post, the change product key option is not same as clicking on the link I told you about.

 

Yes, I do have 1511 (10586) patch installed.

So, this is how it looks after clicking the link 'I have a W10 Pro key.' and I'm still confused. Should it work or not?

edit2:\> Well, I called the activation line to ask if my key is alright but there's only a machine, which goes directly to entering first block of installation ID which I do not have, obviously. No option to speak with live person.:-( I even tried another (last) W7Pro key I have available, no luck, same thing.

 

To update Win 10 Home to Pro you need a Win 10 Pro key (even the generic)

To activate Win 10 Pro a Win 7 COA key can be used (I assume it's from the same PC being updated?
(...otherwise it's contrary to the EULA, and NavyLCDR will send the Marines to your house and confiscate your PC's)

 

Microsoft tells you how to do it:

Read the very last link: Upgrade using a Windows 7 Ultimate, Windows 7 Professional, Windows 8 Pro, or Windows 8.1 Pro product key
@Superfly - you funny guy, you!

 

So it was my fault in the end! Thanks guys, now everything runs nicely, Bitlocker already crunches my drive and everything is all unicorns and rainbows. You guys have nice funny forum here, I'll gladly come again to see more.
Thanks again.

 

You'll need to purchase a 'Windows Anytime Upgrade' key.
You can also use Windows 8 Pro Pack, Windows 8.1 Pro Pack or Windows 10 Pro Pack.
Ebay also has some cheap Windows 10 Enterprise upgrade keys.

Hope this helps!

Yours sincerely, Lorraine Nicolson.

 

Just curious, why do you think he couldn't use his Windows 7 Pro product key? Microsoft said it would work (post #10) and apparently in post #11 it did work as Microsoft promised.
