If you are not interested in Windows 10, but are plagued with the icon and prompts to upgrade to Windows 10, you can get rid of this. The Windows 10 Upgrade comes with Windows Update in KB3035583. You can uninstall this update in order to remove the Windows 10 Upgrade.

Note that after removal, you will have to hide the update from Windows Update to prevent it from being installed again.
