One Reddit poster was in for a nasty surprise after he installed Windows 10 and woke up the next day to discover pictures from his porn collection scrolling across his desktop.

Those who have used Windows Phone will be familiar with their photos appearing in the scrolling tiles on the phone's home screen, but those who are new to Windows 10 might not be prepared for the exposure the operating system will give their snaps.

Redditor FalloutBoS posted his warning:

Loaded up WIN 10 last night and left it on to do its thing. Woke up to wife asking why I set it to rotate all my porn images right on the desk top view. I have no idea how to shut that feature off and that computer is staying shut down until I do. Free windows and a free trip to the doghouse. Thanks Microsoft!!!

Don't make my mistake, keep your private pictures out of My Pictures, no matter how deep you hide them in sub folders.

According to a report by PC Authority the latest update to the Windows 10 EULA (End User Licence Agreement) says that Microsoft can block you from using pirated software and unauthorised hardware peripherial devices :

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.

And it seems that the definition of 'unauthorised' is left to the whims of Microsoft.
