Microsoft swears that users will always be asked before their computer is upgraded to Windows 10, but there are more and more examples that this isn’t always happening. And the latest blunder happened with no less than 120,000 witnesses.

If you’re a gaming enthusiast, you probably heard of Erik Flom, a former professional Counter Strike Global Offensive player who is now a full-time streamer, according to his online profile.

During his most recent live stream, Flom was stunned to see the computer he was playing on automatically starting the Windows 10 upgrade without any prior warning, prompt, message, or anything. One second you buy a hand grenade and then boom, the Windows 10 upgrade starts, rebooting your computer and asking you to sit back and relax because the whole process is performed automatically.

“Everything was turned off”

We know what you’re thinking: Microsoft has no fault this time because Flom most likely enabled the Windows 10 upgrade, so when everything was downloaded and prepared for install, the setup process actually started.

But not according to toe the gamer. “What. WHAT?! How did this happen?” he says in the live stream that you can re-watch on Twitch for yourselves (the Windows 10 upgrade starts after minute 8:54). “I turned off everything,” he adds, clearly suggesting that this was nothing more than a forced upgrade without his consent.

Microsoft hasn’t yet offered us a new statement following this new blunder, but back in March, a company spokesperson told us that users would always be in full control of the Windows 10 upgrade.

“Customers continue to be fully in control of their devices, and can choose to not install the Windows 10 upgrade or remove the upgrade from Windows Update (WU) by changing the WU settings,” the spokesperson told us at that time.

Make sure you watch the Twitch video to see Erik’s reaction when the Windows 10 upgrade starts. It’s priceless. And so are comments posted by viewers in the adjacent chat.
