如何在 Powershell 中列出可执行文件名

Question

I need to list all installed applications in windows. Using powershell and the following command, I can find out the name and some other details of the installed applications.

Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\ * | Select-Object DisplayName

What I want is to also find out the commandline of the applications so that I can run the application using that commandline . So basically I need following informations-

1. Name of the application
2. Command line of the application
3. Start an application using commandline

What might be the possible solution for doing that?

Answer 1

There are an unfortunately large number of ways to interpret "applications installed" on windows.

If you are looking for a list of programs on your path, you can use

Get-Command -Type Application

This list includes programs installed as part of Windows, as well as those added after that, if the installer adjusted the PATH environment variable to make the programs visible at the command line. The list will be big.

Depending on the version of PowerShell you are using, the Get-Package command may be of help. Under PowerShell 5.1, it includes information from multiple sources, including the uninstall programs list in the registry, the windows installer (MSI) database, and information about system updates. That list will be big too, but different from the Get-Command list.

Answer 2

The installed program are located in other registry key:

 HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths

The following script get all programs and the their commandline:

 $q="`""
 Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\*"  |
 Where-Object {$_."(default)" -ne $null} |
 Select-Object @{ expression={$_.PSChildName}; label='Program'} ,@{ expression={$q + $_."(default)" +$q}; label='CommandLine'}

Sample of output result:

    Program             CommandLine                                                                  
    -------             -----------                                                                  
    7zFM.exe            "C:\Program Files (x86)\7-Zip\7zFM.exe"                                      
    AcroRd32.exe        "C:\Program Files (x86)\Adobe\Reader 9.0\Reader\AcroRd32.exe"   
    excel.exe           "C:\PROGRA~2\MICROS~1\Office12\EXCEL.EXE"
