How to run PowerShell commands from the command prompt?

To run Powershell commands from the command prompt or cmd, we need to call the PowerShell process PowerShell.exe.

Example

See the sample example,

C:\> Powershell.exe -Command "Write-Output 'Hello world'"
Hello world

Similarly, you can call any command. We will use another example to get service information

C:\> Powershell.exe -Command "Get-Service Spooler"
Status   Name    DisplayName
------   ----    -----------
Running  Spooler Print Spooler

To run multiple commands,

C:\> Powershell.exe -Command "Stop-Service Spooler -verbose -passthru;
Start-Service
Spooler -verbose -passthru"

Output

VERBOSE: Performing the operation "Stop-Service" on target "Print Spooler (Spooler)".
Status Name DisplayName
------ ---- -----------
Stopped Spooler Print Spooler
VERBOSE: Performing the operation "Start-Service" on target "Print Spooler (Spooler)".
Running Spooler Print Spooler

The above command is similar to,

C:\> Powershell.exe Invoke-Command -scriptblock {
   "Stop-Service Spooler -verbose - passthru;
   Start-Service Spooler -verbose -passthru"
}
