Now it's showing as Windows 11 Enterprise and "Not Activated". What should I do?Also I cannot find the product key for the purchase I made.

Cannot activate Win10 Pro after Microsoft Store app purchase

Hello guys,

My laptop came pre-installed with Win10 Home 64bit and I recently purchased a Win 10/11 Pro licence from the Microsoft Store app. Unfortunately, having some issues activating the digital licence for Win10 Pro.

Here is the situation:

• Logged into Microsoft account used for the purchase (also received the email receipt of the purchase)
• Already connected to stable internet

What I tried so far:

Entering the Win10 Pro generic key:



Received error 0x800700005:





Clicking Close returned another error 0xC004F034:





Clicking Troubleshoot re-activated my Win10 Home so still not on Pro.

Thanks for any help.

Can't upgrade from Windows 10 Home to Pro

Hi Bill,

Thank you for posting your query in Microsoft Community. We apologize for the inconvenience caused and will assist you in the best possible ways.

I suggest you to download and create an installation media for Windows 10 Pro form the link provided below:

Download Windows 10

After the installation media is created, suggest you to upgrade to Windows 10 Pro from the installation media. When the upgrade asks for product key, enter the product key purchased for Windows 10 Pro. If it does not accept, suggest you to skip the activation
step. After the Operating System is installed, suggest you to activate by phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select the Region from the list and click Next.
• Call the Toll-Free number provided on top and can activate via phone.

Hope this helps. Keep us posted on the status for further assistance.

You sir, are a star. Thank you so much!

As a final attempt, I followed the last article you sent where downgrading Enterprise to Pro simply meant re-entering the Generic Pro Key again. And it worked! +reps for you <3

In summary, here was the rundown of events in case someone else can find this useful:

1. Buy Win Pro 10/11 digital licence from Microsoft Store app (no product key, licence bound to MS account)
2. 'Buy' button becomes 'Install' in MS Store, click Install (this will result to an error code, do not panic)
3. Reboot device (let Windows updates finish during reboot)
4. Windows magically reboots to a de-activated Win 10 Enterprise (do not panic)
5. Change product key into generic Win 10 Pro key: VK7JG-NPHTM-C97JM-9MPGT-3V66T (this effectively downgrades the 'stray' Enterprise to Pro)

Voila!

Thread marked solved. Cheers!
