Windows 10: Produce Key for Win 10 Pro

I purchased from Microsoft store on April 11 of this year. A couple of days ago, I have a message at the bottom right of my screen that tells me I need to Activate Window. In settings, It prompts me to put my key in. I can't find it. Where can I find it?

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

How do I get the key for win 10 pro?

Hi,

I upgraded from win 10 home edition to win 10 pro. I had to reformat my computer with the factory image restore. It installed the win 10 but I did not have key to upgrade to pro. I have the following information from my Microsoft account. How do I get the
key for win 10 pro?

Here is my computer info where the win 10 pro got upgraded.

• DESKTOP-JP9JK4V
• Dell Inc. XPS 8900
  • Serial #: 3R8F082

Thanks!

Win 10 Pro upgrade using Win 8 Pro product key

I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

So:

How do I either

• activate the Win Pro upgrade, or
• Get my activated Win 10 home back?
