2010年8月3日からWindows XPの起動が遅い。解決編?

2015年5月21日

2010年8月3日からwuauclt.exeとsvchost.exeが異常にメモリを食い、動作が非常に遅くなる問題は以前の記事のRJさんのアドバイスにより無事解決したと思ったのですが、また翌日戻ってしまいました。
Windows Updateを適用しているパソコンではこの現象は起きず、Microsoft Updateを適用しているパソコンのみに現れる現象のようです。また、Microsoft Updateを適用しているパソコンでも、一度Windows Updateに戻し、再度Microsoft Updateをインストールすると、メモリを食う現象は現れないというパソコンもあるようです。(私はダメでした)
私の場合はWindows Updateを使用する状態にしておくと不具合は発生しませんので、しばらくはこの状態で運用することにします。

Microsoft UpdateからWindows Updateに戻し、再度Microsoft Updateに戻す手順をご紹介いたします。
Microsoft UpdateからWindows Updateへ戻すだけにするのか、再度Microsoft Updateに戻すのかはメモリの負荷の状態を試した上で皆さん自身で決めていただければと思います。

1.もし、「Automatic Updates」サービスを無効にしている場合は有効にしておきます。書いてある意味がわからない人は無効になっていないと思いますので気にせず2へ進みます。

2.Internet Explorerを起動し「ツール」→「Windows Update」をクリックします。

3.左側のメニューの「設定の変更」をクリックすると言語の設定の画面が表示されますので、そのまま下へスクロールさせると「Microsoft Update」の使用を停止するという画面が表示されるので、「Microsoft Updateソフトウェアを無効にし、Windows Updateのみを使用する」にチェックをつけ、「変更を今すぐ適用」をクリックします。

3.以下の画面が出ればWindows Updateを使用する状態に戻りました。

Windows Updateのまま運用する方はここで終了です。お疲れ様でした。
Microsoft Updateへ戻す方は、このまま作業を続けてもいいのかもしれませんが、念のために再起動をした方がいいかもしれません。
4.再度、2の手順でWindows Updateを起動させます。

5.Windows Updateのホームの画面が表示されるので、「今すぐMicrosoft Updateをご利用ください」の隣りの「開始」ボタンをクリックし、あとはウィザードに従ってインストールを行ないます。

より詳しい方法を見たい場合はMicrosoftの以下のサイトが参考になります。

2010年8月25日追記
解決編としてMicrosoft UpdateからWindows Updateに戻し、再度Microsoft Updateに戻す手順としてご紹介しましたが、翌日Microsoft Updateのままではメモリに負荷がかかる現象が確認できましたので「解決編?」とし、内容を少し変更しました。

2010年9月15日追記
完全解決編を掲載しました。
