How to upgrade 1511 from Home to Pro?

What version are you running?  Check at Settings > System > About.

Microsoft Windows [Version 10.0.16299.192]

btw I had to get this via cmd line, because this "great" OS closes the system window when I click on about. NOT kidding....

I also tried to enter the pro key via cmd as described in some threads, but also without success.

BTW: I found another thread where ppl had the same issue with same error codes and they solved it. The issue is that the OS got upgraded from win 8 Home to win 10.... their solution was to upgrade with a win8 Pro key to win 10 Pro. This works successfully according their reports. So I tried a generic Win8 pro key. without success again.

No matter if I use win 8 Pro, win 8.1 Pro or win 10 Pro generic key always the same:

1. It detects the key as valid and asks to start the upgrade
2. klick start
3. progress window opens and keeps some seconds on 0%
4. error, upgrade not possible because I have no valid digital license or no valid product key. error code 0x803FA067

But of course windows is activated. Also the activation menu states that it is activated with a digital license linked to my microsoft account.

really funny that this makes so many problems on so many machines.... also just a clean install is not possible, because the Home version is linked to this HW and setup will not even ask for a product key... really good job....not

I know why my main machine will stay at Win7 as long as possible.... problems with app updates from microsoft store also the whole time.... even with workarounds... mentioned only as a side note here... look and feel is not bad, but so many bugs.... just crap.

The change that was made in last version is that one cannot use Default Pro Product Key to change from Home to Pro unless there is already a Digital License for Pro on the PC.  Previously you could do it without the DL being there yet.

If you have a retail Pro Product Key, use it.

If you have a Store Pro Upgrade, sign into the Store account and reapply it. 

I hope this helps.  Feel free to ask back any questions and let us know how it goes.  I will keep working with you until it's resolved.

ah ok, thanks for clarification. Didnt read anything similar about this change so far....

OK, I have a retail key. When I use it there is another error code. 0xc004f050

It says the code doesnt work. According to all the guides all over the net this is "normal" and you have to use the generic key to upgrade and use the retail afterwards...

Thatwhy I wasnt thinking about it,  but now I assume I got a faulty or blocked code, whatever... Is there any chance to check if a code is valid?

update:

I found an old key from win8 pro which I am not using anymore. With this the upgrade worked fine.

PS:

perhaps you should add a FAQ entry that the generic keys dont work anymore... the net is full with this workaround....

There have been some changes lately.  I would try inserting both the Pro Default Product key and your retail Product Key in Activation Settings link to Change Product Key.   http://winaero.com/blog/generic-key-to-install-windows-10-rtm/

Ok... give it another try...

Go to activation mask, <Change Product Key>

-> entering the retail key for Win10 Pro immediately gives error 0xc004f050 ("entered product key does not work"). The screen for entering a key remains open.

-> entering the generic Win10 Pro key from the linked page first opens the "upgrade Windows Edition" mask. Click on <Start> seems to start some process, but stops after 0% installation and error 0x803fa067. After this, I'm back on the activation mask.

I also did a reboot, tried the the generic key first and retail key afterwards, with the same result. My retail key is rejected immediately, the generic key just needs one more step to fail, and the error code differs. But at the end of the day, the result is the same: I keep sticking on Win10 Home.

It it was not for Remote Desktop which I really need for my work, I would give up :(

Hi Kathrin.

I had EXACTLY the same!

Was your machine also original upgraded from win8/8.1 to 10? during free upgrade period?

than you have to enter a win 8 PRO key.... I read it several times and it also worked for me... my win 10 PRO key was rejected with same code like yours....

ppl spend money for win 10 Pro keys for nothing...

this seems to be a HUGE bug.... thanks BILL.... not...
