Most people using earlier versions of Windows have their computers set to automatically install 'recommended' updates by default, possibly explaining why the Windows 10 upgrade took so many of them by surprise.
Microsoft have insisted that updates do not take place without the user consenting to them.
"We continue to recommend (unless you're an advanced user who is prepared to work through some issues) that you wait until the Windows 10 Creators Update is automatically offered to you," John Cable, director of program management for Windows servicing and delivery, said on Tuesday.
"When your device becomes eligible for the Creators Update rollout, you'll be prompted to make some important choices on your privacy settings before the Creators Update can install." According to advertising stats counter Ad Duplex, around 10 per cent of Windows machines are running the Creators Update.
On a Reddit thread about the unwanted upgrades, one user wrote: "This actually happened to my wife. Trying to finish a midterm project that was due and she got up to do something, came back to find her computer in the middle of the update.
Now, Redmond has urged users to stop manually fetching and installing the code, and instead wait for it to be automatically offered to your computer when it's ready.
While Windows 10 has got great reviews (Microsoft says it has the highest customers satisfaction of any version of Windows), the company's constant nagging to get users to upgrade has been criticised.
Users have complained that their PCs have shut down and upgraded to the new operating system unexpectedly, sometimes interrupting important work and making their computers unusable for hours.
