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
- Sign in with an administrator account.
- Select Start > Settings > Update & Security (Windows 10) or System > Activation (Windows 11).
- If Windows is not activated, select Troubleshoot.
- When prompted, choose I changed hardware on this device recently.
- Sign in with the same Microsoft account that previously had the digital license.
- 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 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:
- Choose the Windows product and activation category.
- Confirm the selection.
- 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.
- Go to the Microsoft support site and follow the “Contact support” flow:
For customers with disabilities or accessibility-related questions, the Microsoft Disability Answer Desk can also provide live assistance.
