Trouble Activating Windows 11 on HP Device

[productbackbone]

I bought an HP device a year ago that came with Windows 11 (Home Single Use) pre-installed. Recently, the Windows license expired, so I purchased a new product key for Windows 11 Home from Microsoft.com. However, when I tried to activate it, I received an error message saying, "The product key entered didn't work. Check the product key and try again."

I've been attempting to get help from Microsoft Support, but I haven't received a response for a week now.

Try ..

1. Open Powershell as administrator
2. Enter the following command slmgr -ipk <Your product key here>
3. Then enter this command slmgr -ato

Example:

slmgr -ipk 82312-ABCDE-AB89X-1234GF-567YA
slmgr -ato

Normal Windows keys usually do not expire unless they are Test keys like MSDN, Insider etc.
