The Cat-and-Mouse Game with Microsoft

Microsoft is aware of MAS 1.5 and its successors. Why hasn't Microsoft killed it?

  1. The Windows 7 Ghost: Microsoft wants users off Windows 7/8.1 for security reasons. If a user uses HWID to upgrade to Windows 10 for free, Microsoft technically gets a more secure user base, even if they didn't pay.
  2. Telemetry: Activated pirated copies still send telemetry data to Microsoft. That data is valuable for debugging.
  3. Legal gray zone of KMS: The technology MAS uses is the same technology large corporations use. Microsoft cannot "ban" KMS without breaking legitimate businesses.

2. Ohook (Office Hook)

Traditional KMS for Office required re-activation every 180 days. MAS 1.5 introduced an improved "Ohook" method. This involves placing a custom DLL into the Office installation folder that intercepts license verification requests. The software thinks it is talking to Microsoft's servers, but the DLL replies "Activated." This is arguably the most "elegant" method because it does not require running background services.
