I am trying to install MSU through below PowerShell script, but its not getting installed. I am not aware of PowerShell scripting. Please someone give me best way to modified this script. I am looking forward to hear.
Start-Process "C:\Installer\windows10.0-kb4520062-x64_9f2a827f11f945d19bd26de6f113f611a38bb8a1.msu" -ArgumentList "/quiet /norestart"
In order to be able to pass arguments to a process launched via Start-Process, the (possibly positionally implied) -FilePath argument must be a true executable, not just a document, which is what a .msu file is.
Therefore, you must pass the executable that .msu files are registered to be processed by explicitly to -FilePath, which is wusa.exe (note the /quiet /norestart at the end of the -ArgumentList argument):
Start-Process `
-FilePath "$env:SystemRoot\System32\wusa.exe" `
-ArgumentList 'C:\Installer\windows10.0-kb4520062-x64_9f2a827f11f945d19bd26de6f113f611a38bb8a1.msu /quiet /norestart'
Note:
In order to wait for the installation to finish, add the -Wait switch.
To additionally check the process' exit code in order to determine whether the installation succeeded, add the -PassThru switch, capture the resulting process-info object in a variable, and then check its .ExitCode property.
However, there is a trick that simplifies the above: pipe the wusa.exe call to Write-Output, which forces it to execute synchronously (as a GUI-subsystem application, wusa.exe would otherwise run asynchronously) and also records its exit code in the automatic $LASTEXITCODE variable:
# Note the "| Write-Output" at the end of the line,
# which makes wusa.exe run synchronously and records its process
# exit code in $LASTEXITCODE.
& "$env:SystemRoot\System32\wusa.exe" C:\Installer\windows10.0-kb4520062-x64_9f2a827f11f945d19bd26de6f113f611a38bb8a1.msu /quiet /norestart | Write-Output
if ($LASTEXITCODE -ne 0)
throw "wusa.exe indicates failure; exit code was: $LASTEXITCODE"
}
'Installation succeeded.'
