Often times I find trying to start Edge on an old data-center jump station and I just click and nothing happens.
This is the direct result of an Edge process that went zombie.
A quick way to kill an Edge session that is acting as a zombie and will not allow you to start a new Edge is from powershell.
Open PowerShell and type
> Stop-process -Name msedgeYou can then even start Edge from PowerShell
> start msedge
