Windows 10: Upgrade from home to Pro with another PC's key

Hello, all, I would like to know about this since long.


If I have a serial key of Windows 10 Pro from another PC, Can I update my Windows 10 Home licence to Pro version?


I have a Windows 10 Home version and the serial key/product key is from another PC which has never been updated to Windows 7 to Windows 10 but the version is Windows 7 Pro.


Please reply soon and if anyone can't understand please comment so that I can elaborate more.

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:

https://www.microsoft.com/en-in/software-download/windows10

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.

 

Query on Clean installation of Windows 10 Pro on Windows 7 Pro PC.

Original Title: Windows 7 Pro (from MS upgrade key) to Windows 10 Pro - Clean Install

My Gateway NV7923U X64 came with Windows 7 Home installed.

I purchased an upgrade key from MS and upgraded to Windows 7 Pro.

I need to upgrade to Windows 10 Pro and then do a clean install.

• Will my existing upgraded Windows 7 Pro now upgrade to Windows 10 Pro automatically, or do I need to perform additional steps?
• Will I be able to do a clean install and have Windows 10 Pro after upgrading?

 

Will Windows 8.0 pro upgrade key work?

The answer to that question is yes it will activate Windows 10 Pro. What it won't do, though, is trigger an upgrade from Windows 10 Home to Pro.

1. Install Windows 10 Pro - not activated. Enter Windows 8/8.1 Pro upgrade product key. It will activate.
2. Install Windows 10 Home. Change product key. Here a Windows 8/8.1 Pro upgrade key (and any Windows 7/8/8.1 Pro product key) will be rejected. Instead enter the Windows 10 Pro generic product key and the upgrade to Pro will be triggered. Now you have a non-activated Windows 10 Pro installed. Change product key again, enter the Windows 8/8.1 Pro upgrade product key and it will activate.

Now - this is all assuming that the Windows 8/8.1 Pro upgrade product key has not been blocked from automatic activation. What I don't know is if phone activation will work in that case - or if the user must actually install Windows 8/8.1 Pro and activate it via phone first. My Windows 7 product key (good for 3 license family pack) has been blocked from automatic activation and I have to call the recorded phone line every time.
