Install this ... it stops the notices & will get rid of the files Microsoft has downloaded, if they’ve gone that far. I have it on two laptops, one of which already had the files on it - got rid of everything, working well:
GWX Control Panel

Per the link:
GWX Control Panel is the easiest way for users of Windows 7 and Windows 8.1 to protect their computers from Windows 10. With GWX Control Panel you can: Remove the “Get Windows 10” icon that appears in your notification area, prevent your Windows Update control panel from upgrading your computer to Windows 10, prevent your computer from secretly downloading Windows 10 installation files, detect and remove the hidden Windows 10 installation files if they’re already on your PC, optionally monitor your computer for unwanted Windows 10-related settings and files- and beginning with version 1.7 you can now easily delete some hard-to-remove program files that are known to cause Windows 10 upgrades and annoyances.
GWX Control Panel is free software that really works, is safe and easy to use, and gives you the option to re-enable the icon and upgrade notifications if you’re ever ready to move forward with Windows 10.
Got it yesterday. : )
MS in essence announced it would install 10 on my computer in a few days and that there wasn't anything I could do about it except postpone the install on a daily basis. With that, MS set a new level in marketing obnoxiousness.
Downloaded your link and the problem appears to have evaporated. Perhaps at the corporate level MS will feel in the totality the moments of concern experienced by its millions of users.
