Prevent the Windows 10 upgrade from downloading onto your system

A recent windows upgrade added an application that offers the upgrade to Windows 10.

Since KB3035583 was released as an Optional or Recommended update based on your operating system, 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.

However, if you did install that update then it can be uninstalled through Windows Update.


Step 1. Open up Windows Update and click on “View update history”.


Step 2. Click on “Installed Updates”


Step 3. In the search box in the upper right corner type in “kb303558”. If the update is on your system it will show up in the results.


Step 4. 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


Step 5. The system may need to be restarted to complete the removal. Restart your computer if prompted to.


Step 6. If you do not want to see the update any more be sure to hide it by right clicking on the KB3035583 listing in Windows Update and selecting “Hide this update”.
