You are wrong, like others on here I have 3 Win 10 upgrade notifications hidden, one of which is a different size, these were listed as Optional however unlike other Optional updates these were pre-ticked.
I have never 'reserved' in the GWX popup.
The recommended settings for updates is the first one 'install updates automatically (reccommended)'
Most people are wise enough now to select the next to last option in Windows updates, but they are still pushing the Windows 10 update by pre-ticking it.
I notice those three Win 10 hidden update notifications have today been removed presumably by MS.
My Laptop manufacturer says the projected date for possible Win 10 upgrade for my model is Nov 2015(originally it was Jan 2016). The support site lists no Win 10 drivers yet, I've checked, there are only the manufacturers utilities for Win 10.
