Are you using pirated software? If so, you may get some unwanted attention from the software manufacturer until you switch to a genuine product. While genuine Windows users will be left undisturbed, users of pirated software will get regular alerts which read thus: “This copy of Windows is not genuine; you may be a victim of software counterfeiting.”
Come June, and your pirated desktop software may cause you quite a bit of irritation. You may get a pestering pop-up box that will remind you during start-up, log-in and at regular intervals, while you use the software, that yours is a pirate version.
