Get bat file to contiune when lauching PowerShell - powershell

I have a bat file that is launching a powerShell script. I would like for the bat file to keep moving after it launches the script and not wait for the powerShell script to complete. Every time right now when i launch the powerShell script the bat files waits till the powerShell script finishes before it moves on. Here is how I'm calling my powerShell script:
PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command "&'C:\Users\sharph\Desktop\test.ps1'"

SS64 'start' help page
You'll want to start it with the start command, like this;
start "" "PowerShell"
This will start a program without waiting for it to close, although that behavior can be re-added with the /w or /wait option. The blank "" is in place of the title, not always needed but generally a safe thing to add.
Perhaps this will work?
start "" "PowerShell" -NoProfile -ExecutionPolicy Bypass -Command "^& 'C:\Users\sharph\Desktop\test.ps1'"
of course, the & had to be delimited to ^&.

Powershell: Can it be kept loaded to make script loading faster?

This is on Win10 and Win11:
I find that a desktop shortcut that runs:
powershell.exe -ExecutionPolicy Bypass -File C:\develop\utils\fetchlatest.ps1
Takes about 3 seconds to even start executing.
Is there a way I can cut this down?

I'm trying to run a powershell script from a batch file batch file but it appears to terminate the batch file

I have a PowerShell script that I'm trying to call in a batch file. The Powershell script renews some credentials used by a subsequent .exe file, which expire after an hour. I would then like to kill the PowerShell script, restart the PowerShell script, and restart the .exe. Here's a simple example that reproduces my problem:
Test.bat
::#echo off
title Started at %time%
pause
Call CallPSWrapper.bat
::Never hits this pause
pause
echo call the .exe here
CallPSWrapper.bat:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -WindowStyle hidden -ExecutionPolicy bypass -NoProfile -File .\MyPowerShell.ps1
MyPowerShell.ps1:
Write-Output "Waiting"
Start-Sleep -Seconds 30
I initially tried calling MyPowerShell.ps1 from test.bat, but tried changing it to being called by an intermediate batch file in the hope that PowerShell would only kill CallPSWrapper.bat.

PowerShell in Task Manager Shows Window

I am trying to make Task Schedule Task so it is completely invisible that a PowerShell script is running so I created a Task on my Win10 machine configured as follows:
Program/Script:
powershell.exe
Add arguments (optional):
-WindowStyle Hidden -command "& {Out-File 'C:\temp\somefile.txt'}" -NonInteractive -NoLogo -NoProfile
When I run this task the powershell command windows pops up for a split second which I don't want.
You can get around this with an 'Application Host' type wrapper. This is a known issue with powershell as a console-based host.
The most convenient way to do this I've found, is to use WScript.exe and run a VBS script that will invoke the process "invisibly", with no console or task bar flicker.
VBS Code:
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
Save the above code in a file with extension '.vbs', and place it somewhere it can be run by the client running the task. This may be in a protected fileshare on the network (if you expect the script it invokes to only run while connected to the network), or locally on the client.
Now when you invoke your console-based script (PowerShell, BAT, CScript, etc.), you invoke this VBS script with WScript explicitly WScript.exe. It also pays to throw on the 'Batch Mode' parameter //B which will suppress script errors & prompts - such as if the wrapper file itself can't be found.
At this point, all you need to do is pass powershell & the command you want powershell to run to this launch sequence:
WScript.exe //B "\\Path\To\Launcher.VBS" powershell.exe -ExecutionPolicy ByPass -file "\\Powershell\Script\To\Run"
I had the same problem, it was resolved at the simple way.
When you create a Task on Windows, just set this configuration:
Open Properties dialog;
Then you check Run whether user is logged on or not;
You can check Do not store password to avoid asking for PC password on Task execution;
In Add arguments (optional): just:
-File 'C:\temp\somefile.txt
This spcript will run without popup the prompt.

Batch script not calling Powershell

I have a batch script that calls a Powershell file in administration mode. I found this code a while ago, and it's worked great ever since:
PowerShell -NoProfile -ExecutionPolicy Bypass -Command
"& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File %PSFile%' -Verb RunAs}";
This time though, I called the batch script from another program. This program says the process worked, but it didn't actually do anything. Examining the logs from echo, I can see the batch script is being called, but it's not calling Powershell. I tried running the batch script manually, and it calls PS fine, so something with how the batch script is being called by the other program is messing with how it calls PS.
This in mind, I tried changing the batch script to directly run my .ps1 file, instead of starting a new admin instance of powershell to start it. My new .bat file looked like this:
Powershell -File %PSFILE% -Verb RunAs
Calling this from the other program sucessfully calls my Powershell script, but I get a bunch of errors from the PS script, since it's not an admin PS session like it needs to be.
How can I change my batch script to call Powershell as an admin, without using Powershell to call itself (which doesn't seem to work with the program that needs to run it)?
EDIT: After trying a bunch of tweaks, I've found I don't even need to be in admin mode to do what this script does. However, I still get access denied errors when running it through the program (admin or not). So something about running it from the program is making it need more permissions than when I run the batch script manually.
This is what I do (inside the .bat file):
If the .bat is NOT running as admin
powershell.exe -Command "powershell.exe 'C:\path\to\script.ps1' -Verb runAs"
If the .bat is running as admin
powershell.exe -ExecutionPolicy Bypass -Command "C:\path\to\script.ps1"
You could use a small utility I wrote called elevate32.exe/elevate64.exe.
elevate64 -- C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -ExecutionPolicy Bypass -File "d:\path to script\scriptfile.ps1"
elevate32.exe (32-bit version) and elevate64.exe (64-bit version) basically elevate whatever command line you pass to them.
You can get it here (ElevationToolkit1.zip):

An alternative is to use a short WSH script that, when called, provokes elevation. An example is on Aaron Margosis' blog here:
https://blogs.msdn.microsoft.com/aaron_margosis/2007/07/01/scripting-elevation-on-vista/
Script:
// elevate.js -- runs target command line elevated
if (WScript.Arguments.Length >= 1) {
Application = WScript.Arguments(0);
Arguments = "";
for (Index = 1; Index < WScript.Arguments.Length; Index += 1) {
if (Index > 1) {
Arguments += " ";
}
Arguments += WScript.Arguments(Index);
}
new ActiveXObject("Shell.Application").ShellExecute(Application, Arguments, "", "runas");
}
else {
WScript.Echo("Usage:");
WScript.Echo("elevate Application Arguments");
}
The limitations of this approach is that it relies on the WSH command-line parser and can't wait for the program to terminate. These limits may not be a problem in your scenario.
Looks like I was totally off as to the problem source. This was a permissions error on some folders I was editing. The program I was running the scripts through acts as a separate service. I had to add that with modify permissions to the security groups of all the folders I was editing. No elevation required in the scripts, just modifying permissions.

How to execute PowerShell script in MoveIT central?

I have a bat file include command em32\WindowsPowerShell\v1.0\powershell.EXE -NoLogo -NoProfile -Command c:\temp\GL_Format_Update.ps1. Then used command line App in MoveIT central to execute bat file. The script can't produce the output file as expected. Command can be run in CMD window successfully. It seems like MoveIT service owner can't execute PowerShell script.
I had a similar issue and found that simply putting the entire command into the CommandLineApp_AppPath was throwing an error. By breaking it up into the path to powershell and the arguments to powershell, I was able to successfully call and execute my script. My script also took 3 parameters.
Create a task with a process. Select the built-in script "Command Line App". Set the parameters as follows:
CommandLineApp_AppPath = C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.EXE
CommandLineApp_AppParms = -NoLogo -NoProfile -ExecutionPolicy Bypass -Command "E:\PowerShell\CreateManifest.ps1 -Folder \\mdcvmsfms11u\DataTransfer\BFClientGateway\Test\Download\2129\PPfAandDP -ManifestName MS_CONTROL_ -OutputType FULL"
