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, False
Which 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"
