Hello everyone, I recently received a new SSD intended for Windows. After reinstalling Windows, I encountered an issue where the activation fails—my key is marked invalid, and it seems I need to have previous Windows versions installed first. I suspect my Windows 8 copy is just an upgrade version, not the original full edition. My question is whether purchasing a Windows 8 key would make it fully activated for that version. I’m really confused about this process.
Upgrade to Windows 7 and enjoy the benefits

Install Windows 7 > upgrade option > gain advantages
During a clean installation of Windows 8 (or 7) using an upgrade copy, you may need to adjust the registry by flipping a 1 to a 0 to show the previous version was present. For future reference: navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/ and set MediaBootInstall to 0. To refresh activation, run the command prompt as administrator and type slmgr /rearm, then restart your computer. This ensures the system recognizes your product key. This method works for Windows 7 and 8, but not for Vista. It was introduced to simplify reinstallation after hardware changes or full reinstalls.
