How to run PowerShell Start-Process without closing the output window? - powershell

I am trying to run the following PowerShell command in CMD:
powershell -Command "Start-Process MSBuild.exe MyProject.sln -Verb RunAs"
I'm running this in PowerShell so that I can get the UAC (for elevated privileges). I'm not sure if there is an equivalent in CMD.
Now, I run the PowerShell script from within a batch file, so that I can double-click and execute. (or put it in the $Path location and call it from anywhere)
But the problem is as soon as it finishes running, it immediately closes, and I cannot see the build error message if any.
How can I wait or pause when MSBuild.exe has finished executing in a new window?

The noexit command keeps your PowerShell window open.
powershell -noexit -Command "Start-Process MSBuild.exe MyProject.sln -Verb RunAs"

in your batch file, add pause to the end
powershell -Command "Start-Process MSBuild.exe MyProject.sln -Verb RunAs"
pause
The issue you're seeing is the command window closing after executing everything in the batch file, rather than powershell closing the shell after it executes.

Running a powershell script as administrator and minimized

So I have set up a task on task scheduler to run a .bat file that runs a powershell script as admin which sets the DNS settings. I figured out how to make the .bat file run minimised, but the powershell window still pops up. Here is the script for the .bat file called "SetDNS". The powershell script's name is "DNS.ps1".
#ECHO OFF
SET ThisScriptsDirectory=%~dp0
SET PowerShellScriptPath=%ThisScriptsDirectory%DNS.ps1
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""%C:\Users\Test\Downloads\DNS.ps1%""' -Verb RunAs}";
I want to change it so that the powershell script does not flash open while it runs. Is there something that I could add to the above code to make it run minimized? I tried to add "start /min" to the above code but it did not work. Help is appreciated.

Run a Powershell script from Batch file with elevated privileges?

I want to run example.ps1 from code.bat
I realize that the start command would run it but require that it be run as admin, how can I do this?
In your batch file:
powershell -Command "&{ Start-Process powershell -ArgumentList '-File C:\folder\psfile.ps1' -Verb RunAs}"
...basically you're using Powershell to run Powershell. The second instance is elevated to Admin and is running your script with those permissions.
Full explanation:
Start-Process can be used to run a program, and also has the parameter -Verb RunAs which elevates the program to run as Admin.
We can't call Start-Process from a batch file as it's a PowerShell command.
But we can run powershell from a batch file, then using the -command parameter to run Start-Process.
We use Start-Process to run powershell (again) and run your script when it is elevated to Admin: -ArgumentList '-File C:\folder\psfile.ps1' -Verb RunAs

Powershell: Run script as administrator causes infinite execution

I am completely new to Powershell. Found a script online for updating Windows, and want to run it as administrator. Have a script that starts a new session and calls that script from a network share:
PowerShell.exe -noprofile -command "&{Start-Process PowerShell -ArgumentList
'-noprofile -file \\path\to\networkshare\00_WindowsUpdate.ps1' -Verb RunAs}"
The problem is that it keeps running the script and opening new windows infinitely. I have searched the Internet and could not find anything specific to my issue. How do I run my script to call the Windows Update script once and prevent it from executing infinitely?
Why are you using PowerShell, to call PowerShell, to run PowerShell?
In .cmd:
RUNAS /noprofile /user:domain\user "powershell -ExecutionPolicy Bypass -Command '& \\Path\update.ps1'"

How to call .cmd file as administrator?

Please let me know how to call .cmd file as administrator from PowerShell script:
The second line below should open as Administrator from a PowerShell script:
Set-Location "C:\client\service"
Invoke-Item "C:\client\service\_install.cmd"
Then the command prompt should wait after execution. This needs to handle in PowerShell script not possible to write in _install.cmd file.
Batch-scripts runs in CMD.exe, so you need to start a CMD.exe process as admin.
Start-Process -FilePath "C:\Windows\System32\cmd.exe" -ArgumentList "/k","C:\client\service\_install.cmd" -Verb RunAs -Wait
Start-Process is the cmdlet to start a process
-FilePath "C:\Windows\System32\cmd.exe" starts cmd.exe process
-ArgumentList "/k","C:\client\service\_install.cmd" tells cmd to leave the console open after running the script (is this what you wanted? if not, replace with /c so the cmd-window will close when done). The second argument is your script.
-Verb RunAs tells Start-Process to start the process as admin (you will recieve a UAC-window if enabled)
-Wait tells Start-Process to wait until the process is finished. With cmd /k this means after you exited the command prompt. If you've changed that to cmd /c, then it waits until the script is done.
If you need to change the working directory inside the cmd-file, then you need to modify the .cmd, or write a wrapper-script, like:
#echo off
cd /d C:\client\service
C:\client\service\_install.cmd

Run powershell in new window

I would like to run new powershell window with parameters. I was trying to run following:
powershell -Command "get-date"
but everything happens in same console. Is there a simple way to do this?
To open a new PowerShell Window from PowerShell:
Start-Process PowerShell
Or my personal favorite:
Start-Process PowerShell -WindowStyle Maximized
Then you could typeGet-Datewithout having to deal with the -ArgumentList's tendency to close itself. I still haven't found a way to open a new PowerShell process with the -ArgumentList Parameter, without it immediately closing after it runs. For Instance:
Start-Process PowerShell -ArgumentList "Get-Date"
or simply
Start-Process PowerShell -ArgumentList Get-Date
Will Close Immediately after running the process.
In order to get it to wait before closing you could add:
Start-Process PowerShell -ArgumentList 'Get-Date; Read-Host "Press Enter"'
Since the -Wait Parameter seems to do nothing at all in this case.
FYI - PowerShell Suggested Syntax is actually:
Start-Process -FilePath "powershell.exe"
But since PowerShell is a standard Windows Application in the %SystemRoot%\system32 Environment Variables the command line(s) should recognize a simple
Powershell
Command
Use the start command. In a CMD prompt, try:
start powershell -noexit -command "get-date"
For Start/Run (or Win+r) prompt, try:
cmd /c start powershell -noexit -command "get-date"
The -noexit will tell Powershell to, well, not to exit. If you omit this parameter, the command will be executed and you are likely to just see a glimpse of a Powershell window. For interactive use, this is a must. For scripts it is not needed.
Edit:
start is an internal command for CMD. In Powershell it is an alias for Start-Process. These are not the same thing.
As for why the window is black, that's because the shortcut for Powershell.exe is configured to set the background blue.
To call a PowerShell (PS) script in a second terminal window without exiting, you can use a script similar to:
Start-Process PowerShell -ArgumentList "-noexit", "get-date"
or if you need to run another script from a specific location:
Start-Process PowerShell -ArgumentList "-noexit", "-command .\local_path\start_server.ps1"
