If you're running Windows 7 on a machine capable of using Windows 10, chances are you getting swamped with ads from Microsoft telling you to upgrade.

Last month, Microsoft said it accidentally tried to make Windows 7 and 8 machines automatically upgrade to Windows 10 and said it fixed its mistake.

But some people on Twitter are complaining that even from Microsoft's latest upgrade this month, they are being plagued by nagging upgrade notices that take over their whole screen with no obvious way to turn them off.

If you like your Windows 7 PC the way it is and don't want to upgrade, that doesn't make Microsoft's nagging go away.
