How to stop the Windows 10 Upgrade from downloading on your system
So far, I can see little reason to upgrade to Windows 10. Windows 10 uses your bandwidth, installs keyloggers and tracks your browsing. It’s not a classic OS like XP or Windows 7.
Since KB3035583 was released as an Optional or Recommended update based on your OS it might not be installed if you avoid those types of updates. If that is the case then you have no further action to take.
If however, you did install that update then it can be uninstalled through Windows Update.
Open up Windows Update and click on View update history.
Click on Installed Updates.
In the search box in the upper right corner type in kb3035583. If the update is on your system it will show up in the results.
Click on the KB3035583 entry in the search results and you will be asked if you are sure you want to uninstall it. Click Yes to remove it.
The system may need to be restarted to complete the removal.
