In this blog we provide a solution that enables administrators to run PowerShell scripts silently.
Many of us have tried to launch Powershell.exe silently with the following parameter:
Powershell.exe -WindowStyle Hidden...But we still see a flash of the blue PowerShell console, even if for a split second. Unfortunately since PowerShell is console-based, there is no native way around this. The only other, relatively simple solution, is to use VBScript to launch it. And I discovered a very handy script over at StackOverflow:
On Error Resume Next
ReDim args(WScript.Arguments.Count-1)
For i = 0 To WScript.Arguments.Count-1
If InStr(WScript.Arguments(i), " ") > 0 Then
args(i) = Chr(34) & WScript.Arguments(i) & Chr(34)
Else
args(i) = WScript.Arguments(i)
End If
Next
CreateObject("WScript.Shell").Run Join(args, " "), 0, FalseWhich you can launch like so:
WScript.exe /b "\\path\to\silent.vbs" powershell.exe -ExecutionPolicy ByPass -file "\\path\to\powershell.ps1"or another example:
wscript.exe /b "\\path\to\silent.vbs" powershell.exe -ExecutionPolicy Bypass -Command "New-Item 'HKLM:\SOFTWARE\Test' -Force"
