如何为Out-GridView列添加自定义对象？附远程获取安装程序代码

Nice work on the initial script to pull installed apps from both 32-bit and 64-bit registry paths! Adding custom columns to your Out-GridView output is straightforward using calculated properties with Select-Object—this lets you inject new, meaningful columns alongside the existing app data.

Step 1: Add an Architecture Column (Distinguish 32/64-bit Apps) #

Since you’re querying two separate registry paths, adding an Architecture column will help you quickly identify which apps are 32-bit vs 64-bit. Here’s the modified code:

$installed_apps = Invoke-Command -computername P1184CDC -scriptblock {
    # Fetch 64-bit apps and add Architecture column
    Get-ItemProperty "HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*" |
        Where-Object DisplayName -ne $null |
        Select-Object *, @{Name='Architecture'; Expression={'64-bit'}}

    # Fetch 32-bit apps and add Architecture column
    Get-ItemProperty "HKLM:\Software\wow6432node\Microsoft\Windows\CurrentVersion\Uninstall\*" |
        Where-Object DisplayName -ne $null |
        Select-Object *, @{Name='Architecture'; Expression={'32-bit'}}
}

$installed_apps | Out-GridView -Wait

The @{Name='Architecture'; Expression={'64-bit'}} syntax creates a calculated column:

• Name sets the column header in Out-GridView
• Expression defines the value for each row (here, hardcoding "64-bit" or "32-bit" based on the registry path)

Step 2: Add Additional Custom Columns (e.g., Formatted Install Date) #

If you want to clean up raw data like the default InstallDate (a string like 20231005), you can add a formatted date column. Here’s how:

$installed_apps = Invoke-Command -computername P1184CDC -scriptblock {
    # 64-bit apps with Architecture and Formatted Install Date
    Get-ItemProperty "HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*" |
        Where-Object DisplayName -ne $null |
        Select-Object *, 
            @{Name='Architecture'; Expression={'64-bit'}},
            @{Name='InstallDateFormatted'; Expression={
                if ($_.InstallDate) {
                    [DateTime]::ParseExact($_.InstallDate, 'yyyyMMdd', $null).ToString('MM/dd/yyyy')
                } else {
                    'N/A'
                }
            }}

    # 32-bit apps with Architecture and Formatted Install Date
    Get-ItemProperty "HKLM:\Software\wow6432node\Microsoft\Windows\CurrentVersion\Uninstall\*" |
        Where-Object DisplayName -ne $null |
        Select-Object *, 
            @{Name='Architecture'; Expression={'32-bit'}},
            @{Name='InstallDateFormatted'; Expression={
                if ($_.InstallDate) {
                    [DateTime]::ParseExact($_.InstallDate, 'yyyyMMdd', $null).ToString('MM/dd/yyyy')
                } else {
                    'N/A'
                }
            }}
}

$installed_apps | Out-GridView -Wait

Step 3: Limit Columns for Clarity #

If you don’t need all the default properties returned by Get-ItemProperty, replace * with a list of specific properties to keep your Out-GridView focused:

Select-Object DisplayName, DisplayVersion, Publisher,
    @{Name='Architecture'; Expression={'64-bit'}},
    @{Name='InstallDateFormatted'; Expression={...}}

Feel free to adjust the calculated properties to match any custom columns you need—whether it’s a status flag, a parsed version number, or something else!
