UPDATE: It has since been pointed out to us that the information in this article is not accurate. While Microsoft can block your access to services such as Bing or Xbox Live, it cannot remotely disable a copy of a third-party software installed on your hard drive. You can read about it in more detail here.
Microsoft now has the ability to remotely uninstall any pirated games that are played on a machine using the Windows 10 OS. While the relevant section of their EULA is not specific as to what exactly constitutes unauthorized software, we know that software updates will automatically check your software versions and prevent you from using Microsoft’s Services, playing counterfeit games, or using unauthorized peripheral hardware.
“Sometimes you’ll need software updates to keep using the Services. We may automatically check your version of the software and download software updates or configuration changes, including those that prevent you from accessing the Services, playing counterfeit games, or using unauthorized hardware peripheral devices. You may also be required to update the software to continue using the Services.” — Microsoft EULA, Section 7b
The updates that will prevent the use of prohibited software and hardware will no longer be voluntary. According to a recent clause added by Microsoft to their EULA, “by accepting this agreement, you agree to receive these types of automatic updates without any additional notice.” This essentially means that Windows 10 devices will automatically download and install these updates, rather than allowing the user to choose if and when to install them.
