Windows 10: Can't run some built-in apps like OneNote since replacing motherboard

I was having some issues with my new-at-Christmas laptop - Dell Inspiron 5559 - and the Dell tech support guy sent a tech to replace my motherboard. That was a couple of weeks back. At about the same time, I noticed that OneNote wasn't working any more; it would show the splash screen then crash after a few seconds. I can't be 100% positive that the change of motherboard caused the issue because I didn't note the date of either event.

The motherboard replacement came with a new license key, which I keep in a safe place. The motherboard replacement fixed the problem I was having with my RJ45 jack - the first time I used it, it wouldn't release my cable, then I more-or-less damaged it to finally get the cable out again - but didn't resolve the power issues I was having. (The computer kept complaining about the AC Adapter, both the original Dell one and the offbrand replacement I bought.) Today, the tech came back and replaced the AC Adapter with a new Dell one and now my power issues are resolved.

But I still can't launch OneNote. I tried upgrading OneNote from the store but the upgrade failed on error code 0x80073CF6. When I started researching that, I found several threads about it but no consistent resolution. In skimming those threads, I also noticed that people reported problems with other built-in apps as well. I tried some of mine, like Calculator, and it's not working any more either: it starts to launch, then crashes while showing the splash screen. I can copy and paste Event Viewer incidents if that would help diagnose this problem.

I'm wondering if I have to re-register the operating system in some way due to the replacement motherboard? If so, how do I do that? I'm guessing that Windows is using the key that applied to the old motherboard and not finding this consistent with whatever code it gets from the new motherboard.

Replacing a bios on a user built machine and licencing....

We built a PC from retail parts and the PC has had a FPP Windows 7 Pro Retail and upgraded to Windows 10 via the free upgrade.

We had a bios corrupt on the motherboard its self. We are not replacing the whole board just the bios chip.

I was curious as to if that would affect licencing or not since Microsoft does refer to the whole motherboard but not individual parts like the bios being replaced.

I seen some answer the question for OEM but since we not OEM I don't know if it be a different situation or not cause the windows key for us is not in the bios.

 

Motherboard Replacement

My motherboard that I've been using for the last two years in a PC I built myself has recently developed a fault, and as it is still under warranty I'm trying to get a replacement. If I can get one (and I'm not sure) I'm wondering whether I will have to
buy my Windows Product key again as to the best of my knowledge the OS is linked to the motherboard so replacing the motherboard will get rid of my copy of Windows.

I bought the product key on the Windows store online (It was Windows 8.1 Student Pro at the time but now upgraded to 10) so is there some way I can explain to Microsoft that I'm replacing a faulty Motherboard not upgrading my system so I don't have to purchase
the same product again?

Sorry if I've misunderstood, it's been a while since I installed the OS and I can't quite remember how it all worked but I'd really like to not have to purchase Windows again if I am able to get a replacement Mobo.
