The Inquirer website discovered that even if you didn’t “reserve” your copy of Windows 10, the installation files are still downloaded to your Surface.
When they asked Microsoft, they got the following response…
“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.”
You can remove the Windows Update responsible for the Windows 10 pre-load easily enough by removing the KB3035583 update (see our article: Remove Windows 10 Upgrade Notification From Surface) and the hidden $WINDOWS.~BT folder but, we’re actually more interested in what you think about this whole mess.
If you have an opinion, head on over to the Forum and leave it in our Topic of The day – Windows 10 Preloads.
