Visual studio setup

Hi @Esko Toppila ,

Thank you for sending us your concern.

From my understanding, your Downloads folder suddenly has many VisualStudioSetup files. In this case, the issue may not be related to Visual Studio itself, because this file is the bootstrapper and can only be downloaded through a browser. Visual Studio Installer or App does not automatically download this file, and it is not used for update purposes.

Please check if there is any browser window open that might be pointing to the Visual Studio download link. If your computer is an organization managed device, an admin may also download this file and place it in your Downloads folder without your knowledge.

Hope this helps! If my answer was helpful, please consider marking it so others with the same issue can benefit as well. You can follow this guidance to see how to do it. 

I look forward to hearing from you soon. 

Visual Studio setup executables appear when the installer checks for or downloads updates. To reduce how often this happens, adjust the Visual Studio update behavior in the IDE:

1. Open Visual Studio.
2. Go to Tools > Options.
3. Expand Environment and select Product Updates.
4. Change these options as needed:
   • Turn off Automatically download updates if frequent background downloads are not desired.
   • Turn off Automatically apply the latest update on close ("Always update on close") so updates only occur when manually requested.
   • Choose an installation mode such as Download all, then install so downloads and installs happen less often and more predictably.

After these changes, updates (and their setup programs) will only appear when manually triggered or according to the less aggressive settings configured, effectively reducing their frequency.
