The Windows 10 icon appeared with Windows Update KB3035583.
Go to the Windows Update dialogue box. Click “Installed Updates” in the bottom-left corner.To quickly find KB3035583, you can sort by name or type
it in the search bar at the top right. Once you’ve located it, right-click and choose “Uninstall”.
When you select to uninstall this update, you’ll be asked to confirm and then you will need to restart your computer. Once your computer restarts,
the “GWX.exe” and its associated “GWXUX.exe” applications will be removed and the system tray icon and resulting dialog will go away
permanently.
KB3035583 returns if you don’t hide it. If you have Windows updates set to download and install automatically, this means that if you uninstall this
update, it will be reinstalled automatically a few days later.
To hide the KB3035583 update and prevent it from being reinstalled, right-click on it in the Windows Update application and select “Hide
update”.
I've used this method, and so far, so good.
There’s also a registry hack that you can use to prevent the icon from showing up. WARNING: I would only try this if the above did not work for you.
I usually don't recommend anyone messing around with the registry unless you know what your doing.
Open up regedit.exe using the Start search or by hitting WIN + R and pasting it into the field. Then browse down to the following key, creating it if
it doesn’t exist:
HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsGwx
Once you are there, create a new 32-bit DWORD value on the right-hand side named DisableGwx, and give it a value of 1.
