This almost happened to me at work. I'm forced to use a Windows computer there, and a few days ago it showed a pop-up that it had scheduled a Windows 10 update for the night. As usually, I clicked the little X to cancel, but no, it was still scheduled. I had to go unschedule it. Seriously Microsoft?
Good thing I'm Microsoft-free at home, except for a wireless xbox controller, Sidewinder joystick and Microsoft remote, which is surprisingly good hardware. Ironic that it runs flawlessly under Linux!

The worst thing about updating to win 10 is that after the upgrade your pc isnt working as it supposed to do so.
I am talking about the drivers that win 10 is installing after the update are totally messed up.
I had pcs that were disconnecting from the network while working and other hardware driver issues...
I had to reinstall every driver again to my clients from the manufacturer but I have used a DriverPack solution instead of searching for each driver :P

This is why I always leave a customer's freshly formatted Win 7/8 PC with "Check for updates but let me choose whether to download and install them." as their Windows Update settings. Updates/Upgrades should always be the user's choice, there's a reason why it's called a PC.

One of the best things I appreciate about Linux is that the user is in control of the system, not the other way around.

kwwkwkwkwkwk

say hello to win 10

iptables FTW, marvellous bit of software available on most routers :P

Personally have win7 for duel boot if needed as my son to also does,

Never seen this update come up! Oh, wait I know how to use a computer.....
