According to Myerson, if during the upgrade process Windows can’t be verified a watermark will appear in the bottom right corner of the screen notifying the user. In previous versions of Windows, the message said “This is not a genuine copy of Windows”, we still don’t know how the new watermark looks like, but Microsoft is likely to show a similar message. The company advice that if you buy a machine that displays the watermark message, you should return the product immediately and demand a genuine Windows device. In addition, the software maker says that non-genuine versions of Windows won’t be left in the cold and the company will soon announce a campaign with partners to offer a “very attractive” deal to upgrade to Windows 10. While the company is finally being more clear on what’s going to happen when users try to upgrade to Windows 10 from a pirated version of the operating system, there is still a few questions yet to be answered. For example, once the watermark appears will users have a limited number of days to obtain a valid product key? Will Windows 10 start rebooting after a certain number of days? And will the operating system continue to receive updates? Also, it’s unclear how Microsoft’s offer will work, because if it’s a very good offer, how this will stop customers from installing a pirated version of Windows to then upgrade to Windows 10 for less money?
