Quote:If you run a device that is powered by Microsoft's Windows 10 operating system, you may have noticed Microsoft Edge processes in the Task Manager or another program even if you don't run the program.

These processes, MicrosoftEdge.exe, MicrosoftEdgeCP.exe, and MicrosoftEdgeSH.exe, show up as suspended in the task manager.

The processes use no CPU or memory in suspended state; some users may prefer to block Microsoft Edge from running in the background even in suspended state. If you never use Edge, there is virtually no reason why it should launch in the background.

Note that the process works fine on recent versions of Windows 10. It may not work with the not-yet-released Chromium-based version of Microsoft Edge; we will see.

The process requires editing of the Windows Registry and a Settings change. Note that you can still run Microsoft Edge on the device.
