Windows 10: My newly built pc wont show up in the list of devices link to the account

I just built a new pc, i was just going to activate windows with a digital license linked to my microsoft account but my new pc wont show up in the list when trying to activate a device. However when I log in on the account on the web I can see my new computer with my devices.I have login with the same account on both pcs and the old pc is "activated with digital license linked to microsoft account".What should I do?

:)

 

Microsoft Account devices list.

Thank you again but thats not the problem either.

I should be able to login to my Microsoft online account from any of my 4 PC's and see the exact same devices listed i.e. all 4 PC's should show up within the account devices list but they dont. Each PC displays a different device list.

 

Devices linked to MS account - an oddity

Win10 21H1 build 19043.1526 I'm preparing to replace the motherboard and CPU on one of my computers. I usually use local account on them, but I switched to using my MS account on the one I'm going to upgrade and displayed Devices on my MS account to see what it showed. I was surprised to to see (in addition to the one I'm going to upgrade) two other computers listed - computers that are using local accounts. And least one of those computers shows "Windows is activated with a digital account linked to your Microsoft account" even when it's using my local account. Cool, thinks I! I don't need to use my MS account on the PC I'm about to upgrade. So I switched back to my local account ... and the PC disappeared from my MS account. *Sad I tried switching back and forth a couple times with a couple reboots thrown in with the same result. This PC shows in my MS account only when I use the MS account rather than the local account. But sometime during this futzing around another computer showed up in the MS account's list of linked devices: a laptop that also uses only local accounts. And that laptop hasn't been powered on today so I have no idea why it was missing earlier and shows now.*Confused The devices that show in my MS account's list of linked devices are:

1. a Surface Pro tablet ordered from MS
2. a keyboard for that tablet, also ordered from MS
3. a homegrown PC that originally had an OEM copy of Win7 Home, upgraded to Win7 Pro, requiring my MS account and Troubleshooter to upgrade to Win10, and another use of my MS account and Troubleshooter for a motherboard and CPU replacement a couple years ago (so who know what MS thinks of that copy of Windows)
4. a Lenovo laptop with an OEM copy of Win10 Pro. (I don't remember ever using my MS account on it, but I guess I must have.)

At any rate, I assume I need to be using my MS account on the PC right before and after the hardware change in order for the Troubleshooter to get my activation to work, and I assume I can switch back to my local account once the re-activation is complete. But I really don't understand what I'm seeing on my MS account's list of linked devices.

 

PC not showing up on device list

So my PC wont show up on my device list on my microsoft account. I've never really explored the ins and outs of having a microsoft account until recently when I discovered I had to download a windows 10 compatible version of a game in order to update it.
After purchasing said game on my microsoft account I am prompted to choose a device from my device list to download the game to, but i have no devices on my device list.

I have already:

1: taken my pc off my microsoft account and then re registered it to my microsoft account

2: downloaded several apps from the store to my pc from the same microsoft account

I'm not really sure what to do at this point. My computer is running the latest windows 10 update.

Please help me I'm trapped in my house and all I want is to play Minecraft
