I recently ungraded my PC's hardware (GPU, motherboard etc) and Windows 10 is telling me to activate my Windows. My windows had been activated before upgrading my hardware and was running smoothly. I do, however, try to activate it in the settings but can't, it prompts me with an error "Windows can't activate right now. Try activating again later. If that doesn't work, contact support. Error code: 0x80080005" I am running a legit copy of Windows 10 (upgraded from Windows 7) and had no issues until upgrading my hardware.
