Moving to new hardware means the licence on the windows install on the SSD needs to be transferred and registered against the new motherboard/system.

Have you used the activation troubleshooter and selected Changed hardware. If you have and you don't see you old system listed with a compatible licence then the licence may not have transfer rights.

Where did the licence originate. Was it:

Previously a Windows 7 or 8 licence and part of the free upgrade to Windows 10.

Supplied by the old system builder.

Bought separately from the system as a Windows 10 licence.

If the system was a known manufacturer, HP, Dell etc. then it is OEM and not transferrable.

To check the licence on the SSD open a Command prompt and enter slmgr /dlv [press return] and post a screenshot of the result.

Switching an SSD with Windows 11 to a new PC is treated as a significant hardware change, so Windows may show as not activated. Use these steps and then contact support if needed.

First try the Activation troubleshooter
1. Sign in with an administrator account.
2. Select Start > Settings > Update & Security (Windows 10) or System > Activation (Windows 11).
3. If Windows is not activated, select Troubleshoot.
4. When prompted, choose I changed hardware on this device recently.
5. Sign in with the same Microsoft account that previously had the digital license.
6. From the list of devices linked to that account, select the checkbox for This is the device I’m using right now, then select Activate.
If the device does not appear, verify that the same Microsoft account that held the original digital license is being used.
If activation still fails
- If the original Windows on that SSD came preinstalled on another PC, the product key might be tied to that original hardware and cannot be transferred. In that case, a new product key or another copy of Windows is required.
- If the license is a retail license and the troubleshooter cannot reactivate it, direct contact with Microsoft support is needed so they can check the digital license and assist with reactivation.
How to reach a real person at Microsoft
- Go to the Microsoft support site and follow the “Contact support” flow:
  1. Choose the Windows product and activation category.
  2. Confirm the selection.
  3. Choose a support option (phone or other live support) when offered.
- If online tools and the troubleshooter do not resolve the issue, customer support can review the activation status and, where eligible, reactivate Windows on the new PC.

For customers with disabilities or accessibility-related questions, the Microsoft Disability Answer Desk can also provide live assistance.
