I have the Windows 10 Home installed in my laptop and I'm using my product key with the command prompt earlier.

I've done as instructed and it still shows me the same thing.

Hi Jennieeee -

Thanks for the response and I do apologize if the method did not resolve the issue

Kindly perform in-place repair on your computer to fix any corrupted system files. In-place repair/upgrade or repair reinstall is a process of re-installing Windows without touching any of your applications or personal files. In this way if there's any data corruption, damaged system files or missing system files on your computer, this repair will fix or repair them.

To start we need to download an ISO file of Windows 10 and save it to your computer. Please follow the instruction on the link below to create an ISO file

After the ISO is created, follow the instructions on the link below created by PaulSey, Microsoft Agent, on how to perform repair install on your computer.
