使用WMIC查询远程主机已安装产品时如何关联主机名？

Yes, you absolutely can modify your WMIC command to include hostnames in the results, or use a simple batch script to segment output by host. Here are two straightforward approaches:

Option 1: Include Hostname Directly in Query Results #

WMI exposes a system property called __SERVER that returns the name of the remote host you're querying. You can add this to your get clause to tie each result line to its host:

wmic:root\cli>/node:@HOSTNAMES.txt /output:INSTALLS.txt product where "name like 'APPNAME'" get __SERVER,name,version

This will add a __SERVER column to your output, making it immediately clear which host each product entry belongs to.

Option 2: Batch Script for Per-Host Segmented Output #

If you prefer cleaner, separated sections for each host (instead of a flat table), use a Windows batch script to loop through your host list and append results with a clear host header:

@echo off
setlocal enabledelayedexpansion
set "OUTPUT_FILE=INSTALLS.txt"

:: Clear the output file first
echo. > "%OUTPUT_FILE%"

:: Loop through each hostname in the text file
for /f %%h in (HOSTNAMES.txt) do (
    echo === Results for Host: %%h === >> "%OUTPUT_FILE%"
    :: Run WMIC query for the current host and append results
    wmic /node:%%h product where "name like 'APPNAME'" get name,version /format:table >> "%OUTPUT_FILE%"
    echo. >> "%OUTPUT_FILE%" :: Add a blank line to separate hosts
)

This script adds a distinct header for each host before its product results, making the output easy to scan. Note: If a host is unreachable, WMIC will write an error message to the file—you can add a ping check before the WMIC command to skip unresponsive hosts if needed.

Microsoft has deprecated WMIC in favor of PowerShell's CIM cmdlets, which are more powerful, flexible, and less error-prone. Here are two better modern alternatives:

PowerShell with Get-CimInstance #

PowerShell's Get-CimInstance replaces WMIC, and it automatically includes the PSComputerName property (the remote host name) in results. You can export to CSV for easy sorting and filtering:

# Read host list from file
$hosts = Get-Content -Path "HOSTNAMES.txt"

# Loop through each host and query
foreach ($host in $hosts) {
    try {
        Get-CimInstance -ClassName Win32_Product -ComputerName $host -Filter "Name like 'APPNAME'" |
            Select-Object PSComputerName, Name, Version |
            Export-Csv -Path "INSTALLS.csv" -Append -NoTypeInformation
    }
    catch {
        Write-Warning "Failed to query $host : $_"
    }
}

CSV output is far easier to work with in spreadsheets or other tools compared to WMIC's plain text.

PowerShell Registry Query (Faster & Safer) #

A critical note: The Win32_Product class (used by both WMIC and Get-CimInstance) triggers a Windows Installer consistency check every time it's queried. This can slow down remote hosts, trigger unexpected repair operations, or cause errors.

For a faster, safer approach, query the Windows Registry directly (where installed programs are normally registered):

$hosts = Get-Content -Path "HOSTNAMES.txt"

foreach ($host in $hosts) {
    try {
        # Query 64-bit programs registry path
        $regPath64 = "\\$host\HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\*"
        Get-ItemProperty -Path $regPath64 -ErrorAction Stop |
            Where-Object { $_.DisplayName -like "*APPNAME*" } |
            Select-Object @{Name='PSComputerName'; Expression={$host}}, DisplayName, DisplayVersion |
            Export-Csv -Path "INSTALLS.csv" -Append -NoTypeInformation

        # Query 32-bit programs registry path (for 64-bit systems)
        $regPath32 = "\\$host\HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*"
        Get-ItemProperty -Path $regPath32 -ErrorAction Stop |
            Where-Object { $_.DisplayName -like "*APPNAME*" } |
            Select-Object @{Name='PSComputerName'; Expression={$host}}, DisplayName, DisplayVersion |
            Export-Csv -Path "INSTALLS.csv" -Append -NoTypeInformation
    }
    catch {
        Write-Warning "Failed to query $host : $_"
    }
}

This method avoids the Windows Installer overhead and works for both 32-bit and 64-bit applications.
