Software Licenses & Keys

Covers buying, verifying, activating, transferring and recovering paid software licences and product keys, including whether a cheap key from a reseller is genuine and what happens when activation fails months later. Does not cover free open-source picks or general app reviews. Evidence: Activation error codes and their meanings, OEM versus retail versus volume licence terms, key-to-account binding rules, deactivation and reinstall sequences, refund windows, and cost differences over the licence lifetime
