Why are there multiple instances of Microsoft Edge?

Unlike early days, every browser runs multiple instances. Each of the tabs is a process, so is the extension or anything else that is running with the primary process. If you are streaming any video service like Netflix, you should also see Media Foundation Protected Pipeline EXE in the list. If you kill any of the subprocesses, you may also see one or more of the tabs closed or an extension crash. However, make sure you don’t have any unsaved work, else you may not be able to recover. This approach makes sure that if one of the tabs crashes, the rest of the tabs remain open. Earlier, if any of the tabs used to crash, it took down all the complete browser. This resulted in the loss of work and work which was not saved or was in between of something. Using thread made it simple, but it can be overwhelming to see so many for a regular user.

What are there multiple instances of Microsoft Edge Update?

According to Microsoft, this is a bug and will be fixed soon.  Asper this thread in the Microsoft Answers by Alexandra-R: This is not intended behavior, and the team is working on releasing a fix. I’ll update here when the fix is available so those of you that have deleted/blocked the executable due to these extra processes can update manually. MicrosoftEdgeUpdate.exe is a process that often connects to Microsoft Server to check and download new features of the  Microsoft Edge web browser. While there can be multiple threads to download to speed up the process, but if there are too many, then that is a problem. That said, Microsoft may reduce the number of instances, but it’s going to be there just less. I hope the post explained to you why there are there multiple instances of Microsoft Edge and Microsoft Edge update service in Task Manager.
