Ok Does WGA in a Legitimate OS check the hardware profile at bootup? How Clever is WGA in a Genuine install?

— short answer: no, WGA does not do a full hardware-profile check each time Windows boots. WGA/validation works by creating a hardware-derived fingerprint and comparing it when a validation is triggered (for example by Windows Update, certain Microsoft sites/updates, or the periodic WGA notification). A genuine install is not policed on every boot.

A bit more detail: WGA is about validating that a copy of Windows is genuine, not about constantly monitoring every hardware change. It looks for significant differences from the stored fingerprint (major swaps such as a motherboard replacement are the most likely triggers) and will then prompt re-activation or show notifications if validation fails. That is different from product activation itself — activation ties a license to a machine and may require re-activation after major hardware changes. OEM licenses are usually tied to the original hardware; retail licenses are transferable.

If you plan hardware changes or hit a validation nag, here are practical steps:

  • Back up your system and record your product key and purchase info before big hardware swaps.
  • If flagged after a legitimate change, run the Windows activation/validation wizard (Control Panel -> System / Activate Windows) and choose online or telephone activation.
  • If online activation fails or you get a false positive, contact Microsoft support with proof of purchase; they can reset activation for genuine users.

Hope that clears it up. And — talking to yourself can be useful; it beats guessing how activation works.
