Ever since someone recommended psExec tool for Windows, I feel it is really handy sometimes when I can not remote desktop onto the target machine. But I do not know many commands out there. Can everyone share any commands that you use for a certain task? In the end, we may have a list of common commands for a system administrator. When the GUI is not available, command is almost the last chance. To start off the discussion, I prepare a few questions, though that's not my only purpose.
Context: commands to achieve the following tasks:
1. How to check what services are installed? So it will be possible to stop/start it?
2. How to create a local user account?
3. How to add a domain user into local administrator group?
4. Any links for administering windows remotely via CLI are appreciated.
