Just finished installing a few patches to a Windows 2003 box and was puzzled about one of the updates “Windows Powershell 2.0 and WinRM 2.0”, now Powershell I knew about but what is this WinRM (Windows Remote Management) all about.
Well from what I can tell it’s rather basic, it’s more or less the corporate (industry standard) replacement of PsExec.exe from Sysinternals, a way to launch commands, scripts etc. remotely. WinRM (Windows Remote Management) offers some additional features and can be used in scripting, from what I can tell it may also work on hardware devices that support WsManagement.
