額，前面的指令碼能自動安裝了，客戶來了句我怎麼知道已經安裝好了？
我答：不是已經顯示success了嗎？
客戶：那以後呢，我忘了怎麼辦？
可以用mmc啊，然後選證書，本地計算機
mmc是什麼？
額……，我寫指令碼吧
==================讓心裡的神獸再奔騰一會兒的分割線================

function Check-Certificate
{
    param
    (       
        [string] $CertName       
    )
    # 我安裝在了LocalMachine的My下，根據實際情況修改
 

    $store = New-Object System.Security.Cryptography.X509Certificates.X509Store "My", "LocalMachine"
    $store.Open([System.Security.Cryptography.X509Certificates.OpenFlags]::ReadWrite)
    $storecollection = [System.Security.Cryptography.X509Certificates.X509Certificate2Collection]$store.Certificates
    $find
 
 = 0
    foreach ($x509 in $storecollection)
    {
        $sub = $x509.Subject
        if($sub.contains($CertName))
        {           
            $find = 1
            break
        }       
    }
    if($find -eq 1)
    {
        "'$CertName' certificate has been Successfully installed!"
    }
    else
 

    {
        "could not fond '$CertName' please run setup.ps1 frist!"
    }
    $store.Close()
}
Check-Certificate -CertName "要查詢證書的subject"
Write-Host 'Press Any Key to exist!' -NoNewline
$null = [Console]::ReadKey('?')

其實就是呼叫System.Security.Cryptography.X509Certificates.*下的類，與用.net差不多，只是要遵循ps1的語法而已
