Windows 10 could allow Microsoft to root around users' computers and delete pirate games or illegally downloaded software, it has been claimed.



Tech fans have dug out a paragraph in Microsoft's terms and conditions which appears to give Bill Gates' cronies the ability to stop people using programmes which have fallen off the back of a virtual lorry.



We already know Windows is watching us using "Big Brother spyware".



But this latest development raises the terrifying prospect that Microsoft could actually step in to prevent us doing anything it disagrees with.



"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," the American tech giant wrote.



Experts fear this controversial passage could allow Microsoft to rifle through around the hard drives of anyone who owns Windows 10, before switching off dodgy programmes.



On the respected website Alphr, tech specialist Vaughn Highfield claimed this tiny paragraph could allow Microsoft to "invade" your computer.



He called for clarity about what powers the horror clause gives Microsoft, saying the wording was "incredibly unclear".



However, whilst tech-heads get cross about at the mere thought of someone violating their silicon sanctum, there are whole industries which could benefit from a tougher approach to piracy.



Anyone working in music, film, games, television or even journalism might welcome the opportunity to stop people ripping off their content for free - and putting their jobs at risk as a consequence.



We have contacted Microsoft for comment and will update this story when it responds.
