Microsoft has admitted that it is downloading the system installation files for Windows 10 to users' machines, even when they have not asked for the upgrade.
The INQUIRER reported that a reader got in touch to say that they had found system installation files for Windows 10 on their machine, which took up a whopping 3.5GB of space.
The download takes effect if a user has Windows Updates on as default, so that security patches are installed automatically.
However, Microsoft confirmed that it is using this feature to install Windows 10.
"For individuals who have chosen to receive automatic updates through Windows Update, we help upgradable devices get ready for Windows 10 by downloading the files they’ll need if they decide to upgrade,” the firm said.
"When the upgrade is ready, the customer will be prompted to install Windows 10 on the device.”
This is causing major problems for users of Windows machines, many noting that their internet use limits have been exceeded because of the huge size of the file.
One user on Reddit wrote: “May have my internet shut off because of this. Rural user here, 15GB/month. We hit that in week two of the month, and had NO idea how," they said.
“Who can I contact about this? Legitimately my internet access may be disabled permanently, and I have no other option outside dial-up.”
The reader who alerted The INQUIRER to the story also said that they were affected by this, which is what led them to the discovery of the files.
"I know of two instances where people on metered connections went over their data cap for August because of this unwanted download," they said.
"My own internet (slow DSL) was crawling for a week or so until I discovered this problem. In fact, that's what led me to it. Not only does it download, it tries to install every time the computer is booted."
Another INQUIRER reader summed up the thoughts of many across the web about Microsoft's actions.
"Surely the default for a PC should be 'If I don't tell you to do it ... DON'T!' Windows Update is there to update my current version of the OS, not to force another version on me," he wrote.
"I wondered why my machine was being such a royal pain in the rear the other day; what's the bet I find the installer clogging up my drive and DSL connection when I check this evening!? How VERY VERY annoying and how VERY dare you, Microsoft!"
