How to Get Rid of the Notification Upgrade to Windows 10

 

To get rid of the icon that is always appearing in Windows 7, 8 and 8.1 permanently, you must follow this steps:
 

•   Uninstall KB3035583 which is responsible for these notifications:
• Control panel, windows update, installed updates, sort by name, "Update for Microsoft Windows KB3035583" (not a Security Update) and uninstall;
• Reboot.

An alternative method is to open a command promp and enter the following:

• wusa /uninstall /KB:3035583

When you're offered the same Update again via Windows Update remember to hide it. If you are using some kind of central patching like WSUS, remember to not Approve this Update.
