After unveiling different "editions" of its upcoming Windows 10 operating system, Microsoft has also discussed genuine vs. non-genuine Windows installations. Genuine users will receive a free upgrade to Windows 10 that also includes security updates for the device's lifetime - but pirates won't receive the same feature.
"When we can't verify that Windows is properly installed, licensed, and not tampered with, we create a desktop watermark to notify the user," Microsoft said in a blog post. "If you ever encounter this watermark on a new machine, I encourage you to return the device immediately to the retailer from whom you purchased it and request a Genuine Windows device."
Instead, Microsoft will try to convince users running pirated copies of different "attractive Windows 10 upgrade offers" to switch to Genuine.
