We may think Windows 10 is a hit but that doesn't mean that everyone is ready for the upgrade, nor does that mean that everyone really wants to make the leap just yet. Unfortunately it sounds as though Microsoft might be making a stronger push than you'd expect for user to update.
According to reports from an Inquirer reader, which were later confirmed by Microsoft, Windows 10 is being pushed out to users 'just in case' they decide to upgrade, even if they have previously declined the reservation offer or have yet to reserve their free upgrade.
In their confirmation to the Inquirer a Microsoft spokesperson explained the reasoning behind the move: “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. When the upgrade is ready, the customer will be prompted to install Windows 10 on the device.”
In other words for users that have automatic updates enabled on their Windows 7 or Windows 8 PCs, Microsoft is pushing the download of Windows 10 upgrade files in order to expedite the upgrade process should the user later decide to upgrade.
At the face of it this may not seem like a big deal, some conspiracy theories aside for most it wouldn't be, however if you are on a limited connection or are using a machine with limited space the download will eat up a big chunk of data. The Inquirer reader noted his PC showed a few odd symptoms as well as major chunk of data being used. He stated : The symptoms are repeated failed 'Upgrade to Windows 10' in
