## MSI與EXE
安裝的軟體有分MSI版跟EXE版，所以要撈兩次

# 列出所有 MSI 安裝的軟體
# MSI方法一:
Get-CimInstance -Class Win32_Product | Where-Object Name -Like 'KeePassXC' | Select-Object Name, Version, IdentifyingNumber
# MSI方法二:
Get-WmiObject -Query "SELECT * FROM Win32_Product WHERE Name Like 'KeePassXC'"  | Select-Object Name, Version, IdentifyingNumber


# 列出所有 EXE 安裝的軟體
$uninstallKey = Get-ChildItem "HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall", "HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" -ErrorAction SilentlyContinue | Get-ItemProperty | Where-Object { $_.DisplayName -and $_.UninstallString }
$uninstallKey | Select-Object DisplayName, DisplayVersion

### Get-CIMInstance Vs Get-WMIObject

Common Information Model (CIM) 是開源的標準，提供systems, networks, applications and services管理信息的定義，由 Distributed Management Task Force (DMTF)開發和維護。

Windows Management Interface (WMI) 是微軟針對windows平臺，對CIM的一種實現。但是微軟進加入了DCOM和RPC。WMI cmdlets使用DCOM訪問遠程機器，但DCOM這玩意屬於“防火牆不友好”，就是要使用很多端口，你得配置好多防火牆規則，遠程機器必須允許135, 445, 1024-1034端口，不方便不說還不安全。

WMI 正在被棄用。如今，PowerShell嚴重依賴PSRemoting及其安全功能。Microsoft推出了基於 CIM 的 cmdlet 和 PowerShell v3.0 的 PSRemoting。任何運行 Windows 7 或更高版本和 Server 2008 SP2 及更高版本的電腦都可以並且應該使用 PSRemoting 而不是 WMI。

## 找出特定軟體並進行移除
以7-zip為例

$target = '*7-zip*'

# 針對MSI版本
Write-Output "嘗試MSI移除"
$query = Get-WmiObject -Class Win32_Product | Where-Object { $_.Name -like $target }
if ($query) {
    foreach ($install in $query) {
        $installName = $install.Name

        Start-Process -FilePath msiexec.exe -ArgumentList "/x $($install.IdentifyingNumber) /quiet /qn /norestart" -Wait
        
        Write-Output "執行移除$($installName)完畢!!"
    }
} else {
    Write-Output "找不到MSI安裝"
}


# 針對EXE版本
Write-Output "嘗試EXE移除"
$query = (Get-ChildItem "HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall", "HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" -ErrorAction SilentlyContinue | Get-ItemProperty | Where-Object { $_.DisplayName -Like $target })
if ($query) {
    $query | ForEach-Object {
        $command = ''
        $installName = $_.Name
        if($_.UninstallString) {
            $command = $_.UninstallString
        }
        if($query.QuietUninstallString){
            $command = $_.QuietUninstallString
        }
     
        if($command){
            cmd.exe /c $command
            Write-Output "執行移除$($installName)完畢!!"
        } else {
            Write-Output "找不到EXE安裝"
        }
    }
} else {
    Write-Output "找不到EXE安裝"
}
