Question

I can't reactivate Windows servers are down

Henrik Josephsen 0

I have upgraded my HW in order to install windows 11. initially I (re)installed win10. When I tried to reactivate my windows (using troubleshoot > I changed hardware on this device recently) I got the message: "We can't reactivate Windows as our servers aren't available right now. Wait for a few minutes or try adding your Microsoft account again"

I have tried for several days with the same answer.

To day Windows 10 did upgrade by itself to windows 11. Same problem.

Please note that this is Danish Q&A Forum, any threads should be posted in Danish. However, I will still provide an answer on English based on your initial response. If you want me to post in Danish, please let me know.

Welcome Henrik Josephsen,

I understand how frustrating it can be when you are unable to reactivate Windows after upgrading your hardware and you are receiving a message that the activation servers are unavailable, even after upgrading from Windows 10 to Windows 11.

To make sure we are looking at the correct scenario, I would like to ask a couple of quick questions first:

Are you signed in using a personal Microsoft account or a work or school account on this device?
Was your Windows license originally activated using a digital license linked to your Microsoft account, or with a product key?

In the meantime, you can try the steps below first to see is the issue is resolved:

Step 1: Sign in to the device using the Microsoft account that was previously used to activate Windows

Step 2: Go to Settings > Accounts > Your info > and confirm the account shows as a Microsoft account and not a local account

Step 3: Go to Settings > System > Activation > Activation troubleshooter

When prompted, select I changed hardware on this device recently
Choose the current device from the list and select Activate

Step 4: Temporarily disable any VPN or third‑party firewall and try activation again

Step 5: Sign out of Windows, restart the device, then sign back in and retry activation

I hope this information helps resolve your issue. If you have any further questions, please don’t hesitate to contact me again in this thread.

To answer your questions:

1: I am logged on with a personal accont (logged on with account.microsoft,com). However I am not seeing all my PCs. The one I am using now is not shown, but my old Game-PC and the updated Game-PC (new motherbard) are both shown

2: The old Game-PC win 10 was a free update from a win 7 base on a Product key

It is a Microsoft account (se answer 1:) but when I try to re-activate my upgrated Game-Pc it sometime do not give the error "Microsoft server is down" but the shown screen wil be empty - no PCs at all wil be shown.

I reality I have three PCs all registered to my Microsoft account (and to my knowledge I have only one account !!!)

I have bought a new license. I have used more than 10 hours to try and solve the problem with the microsoft account and activation. That is too much. Case closed.
