Windows 10: can't activate windows after upgrading [with a key] from win 10 home to win 11 pro....

Hello. After upgrading [with a key] from win 10 home to win 11 pro, win 11 did not activate when the upgrade process was completed. Troubleshooting says: I have a win home digital license, but win pro is installed. Please install win home.

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?

 

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?

 

Old win 10 pro key doesn't activate win 11

Hello,

I was using win 10 pro for 7 years with a multi computer CD key( original)

I recently built a new rig and installed win11 directly and used my old win10 pro CD key.

My old PC was synced with my Microsoft account and I used same account on win 11.

Now win 11 doesn't activate because of hardware change. I followed every possible troubleshoot from windows.

I was able to upgrade to windows 11 for free with my old PC but hardware requirements wasn't met.

I am not able to use my old cd key with win 11 ?
