Windows 10: Windows won't activate even after installing Microsoft 365 several times

I've had a laptop for over a year in our family and recently it came to be mine. I tried to personalize it but it kept asking for the Microsoft to be activated. I clicked on it to try to activate it and it took me to the activation page in Settings but with the message, "We can't activate Windows on this device because you don't have a valid digital license or product key. If you think you do have a valid license or key, select Troubleshoot below. Error code: 0xC004C003" I clicked Troubleshoot and it wasn't able to activate it, and instead prompted us to buy Office 365 we bought it on a different account rather than my own. After installing it and restarting the computer, I was excited to finally be able to use the computer as my own. To my disappointment, that was not the case. I tried installing Office 365 at least another seven or more times. It didn't work. I tried unsubscribing and then buying it again on my own account. It didn't work. I tried opening up Word and signing in through there, to see if that would help activate it. IT DIDN'T WORK. I've tried looking up what my problem is, searching for the documents that came with the computer when we first bought it over a year ago, scouring forums to see if anyone had similar problems. I COULDN'T FIND ANYTHING!!!! I am very frustrated and exhausted with this whole endeavor. If anyone out there has even a shred of knowledge that could somehow point me in the right direction, I would be very relieved indeed. Thank you for reading this, and even if you know nothing, please ask someone who might. Thanks again.

Windows updates won't install!

I had the same problem when i repaired my O/S, i forgot the steps on how to fixed it, but it is in the microsoft support forum.

You have to reinstall the windows updater, then restart the updating service.
