There will be many people very excited about the prospect of upgrading to Windows 10 on the 29th of July.
At the same time there are other users on Windows 7 and 8.1 who do not want any part of the upgrade for a variety of reasons.
Microsoft has confirmed that the new OS, currently in its final stages of development, will be made available for download/install on eligible systems on 29 July 2015.
In preparation for that, back in April, Microsoft released an update (KB3035583) for Windows 7 (Optional) and 8.1 (Recommended) that is called the Get Windows 10 app. It provides the prompt that started appearing on users systems (Windows 7 and 8.1) yesterday and gives you the option to reserve your copy of Windows 10.
But what if you are one of those users with zero interest in the Windows 10 upgrade?
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.
