サンプル スクリプト:Windows Update 関連の設定確認 (get-wusettings.ps1)

かなり強引なつくりで、美しくありませんが、なんとなく作ってみたスクリプト。get-wusettings.ps1(英語版)とget-wusettingsj.ps1(日本語版)。

Get Windows Update Settings from Windows 10 registry (get-wusettings_v3.zip)
https://gallery.technet.microsoft.com/scriptcenter/Get-Windows-Update-bed521e1
(※注:2020/06 で Technet Galallery 廃止されます。なのでコードをこのページの最後に追加)

実行結果はこんな感じ。Windows Update の自動更新の設定、WSUS クライアントの設定、Windows Update for Business(WUfB)のローカルおよびポリシー設定、Windows バージョンをチェック。設定アプリのブランチ選択(1903で廃止)はチェックしてません。(v2 でローカルの SAC/SAC-T もチェック、v3 で最後に ver & build 情報追加と v2 で追加した SAC/SAC-T チェックのバグ修正)


いろいろ設定しているとやかましくなります。おかしな設定を見つけると何となく指摘します(指摘内容はあくまでも自論です)。
Microsoft Endpoint Configuration Manager (旧称 System Center ...)のクライアントかもしれない場合は最後に出力。WMI の root\ccm の存在と、%Windir%\ccmsetup の存在をチェックにて(あくまでもクライアントの可能性)。

(ちゃんとテストしてるわけではありません。あしからず。)

2020/03/16 追記:
※注:2020/06 で Technet Galallery 廃止されるそうなので、get-wiusettings_v3.zip の中身を追記しました。
