Simply enter the command
Enter-PSSession –ComputerName <computer name>
This will let you control a single computer remotely, if you want to control more than one computer simultaneously then enter a command similar to the below
Invoke-Command -ScriptBlock { Get-EventLog System -Newest 5 } -Computername compname1,compname2,compname3
Where the command between the braces is the command you would like to run against the remote servers
Don’t forget, you can still enter commands against a remote computer with WinRM enabled (it’s enabled by default in Windows 2012) by entering the command:
winrs -r:<servername> <command to run>
<command to run> could even be powershell.exe to create a remote powershell session !
