Hi Albright,
If you bought the Windows 11 Pro upgrade separately in the Microsoft Store app, Microsoft says that purchase is delivered as a digital license, and Microsoft’s Windows license terms say stand-alone software may be transferred to another device that belongs to you, as long as you remove it from the old device first. If the Pro edition was preinstalled or bundled with the Acer, it is tied to that licensed device and is not transferable by itself. https://support.microsoft.com/en-us/windows/find-your-windows-product-key-aaa2bf69-7b2b-9f13-f581-a806abf0a886
On the replacement laptop, sign in with the same Microsoft account and go to Settings -> System -> Activation. Microsoft says digital licenses are linked to your Microsoft account and hardware, and the Activation troubleshooter is the tool to use after a hardware change. Because Pro is an upgrade from Home, the replacement device generally needs to be on Windows Home before you apply the Pro license.
If this helped you solve your problem, please mark the answer as helpful so others can benefit. Have a great day!
