In the Task Manager on Windows OS, you may have noticed several processes running in the background; these processes operate silently and carry out specific functions. As a result, these processes are necessary for the Windows Operating System to run correctly.

Several errors in your system could result from disabling any of these processes without understanding what it is used for. Aggregator Host, which we’ll discuss in this post, is one of these background processes.

The Aggregator Host is a file that has to do with Windows. The file’s properties window is usually blank. Users have reported that this process connected to Windows Defender appears and vanishes at random.

  • Control communication between Microsoft Store app and backend servers – This process also ensures smooth communication between the Store app and backend servers.
