Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
To replace an old computer on the devices list with a newer one:
- Sign in to the new Windows PC with the same Microsoft account.
- The new Windows 10/11 device is automatically added to the devices list when signed in.
- Go to Sign in and open the device list.
- Find the old computer and select Remove device.
- If needed, expand the device details, then select More actions > Remove.
- Review the details, check I'm ready to remove this device, and select Remove.
If the new PC does not appear yet, sign in on that PC with the Microsoft account first. Only Surface devices can be added manually by serial number; other Windows 10/11 PCs are added automatically.
If the old PC is being recycled, sold, or given away, back up files and reset the device before removing it from the account.
