直接通过 PowerShell 执行以下命令即可：

Invoke-Expression (new-object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/mosserlee/PSTips/master/Functions/Get-InstalledSoftwares.ps1')
Get-InstalledSoftwares | Export-Csv -Path 'D:\softwarelist.csv' -NoTypeInformation -Encoding UTF8

Export-Csv 的用法参考了这里，输出 CSV 文件然后保存在 D 盘之中，具体的执行内容可以参考源文件：

.Synopsis
   Get installed software list by retrieving registry.
.DESCRIPTION
   The function return a installed software list by retrieving registry from below path;
   1.'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall'
   2.'HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall'
   3.'HKLM:SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'

.EXAMPLE
   Get-InstalledSoftwares
.EXAMPLE
   Get-InstalledSoftwares  | Group-Object Publisher
#>
function Get-InstalledSoftwares
{
    #
    # Read registry key as product entity.
    #
    function ConvertTo-ProductEntity
    {
        param([Microsoft.Win32.RegistryKey]$RegKey)
        $product = '' | select Name,Publisher,Version
        $product.Name =  $_.GetValue("DisplayName")
        $product.Publisher = $_.GetValue("Publisher")
        $product.Version =  $_.GetValue("DisplayVersion")

        if( -not [string]::IsNullOrEmpty($product.Name)){
            $product
        }
    }

    $UninstallPaths = @(,
    # For local machine.
    'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall',
    # For current user.
    'HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall')

    # For 32bit softwares that were installed on 64bit operating system.
    if([Environment]::Is64BitOperatingSystem) {
        $UninstallPaths += 'HKLM:SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
    }
    $UninstallPaths | foreach {
        Get-ChildItem $_ | foreach {
            ConvertTo-ProductEntity -RegKey $_
        }
    }
}

实际上是通过对卸载软件的注册表内容进行遍历，获取需要的信息。
