Microsoft told us: "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.”
Surely this should be an 'opt in' service? Since 5 Aug 2015, I've had 46 instances of 'Upgrade to Windows 10 Pro......failed', yet have never requested any such 'upgrade'...
The 'Error details' shows 'Code 80240020'.
Looking further, I've found that a folder '$Windows.~BT' has appeared on my C-drive. It's some 4.07 Gb in size and includes 15,595 files in 3,380 folders, all of which concern Windows 10.....
M$, what on earth possessed you to force this cr@p on people who haven't asked for it?
