Windows on new motherboard
You're asking whether you need a new Windows license for your PC after upgrading the hardware. It depends on the type of Windows you install—standard edition or Pro/Enterprise. OEM versions usually come with the software included, so you won't need to purchase a separate copy unless you want additional features or support.
You recently changed a component and noticed your copy wasn't working. Microsoft advises keeping track of the current key, noting it down, and using the same key to reactivate if it shows it's inactive. This situation has happened before, even after a few days ago.
