◆Windows Log
「Windows Log」内のファイルが原因となる場合も
その他、チェックしておきたいのは「Windows Log」。「C:\Windows\Logs\CBS」フォルダを見ると、「CbsPersist_*****.cab」という圧縮ファイルが並んでいるはず。その下に「CbsPersist_*****.log」というファイルがあればレッドカード！
「cab」ファイルはシステムのエラーログ記録なので、あって当然（正常）。が、「log」ファイルの方は、何らかの原因で圧縮（cab化）に失敗した残骸だ。圧縮に失敗し続ける＝HDDに長時間アクセスし続ける要因なので、あれば削除してしまおう。（※cabファイルまで消さないように注意！）
◆システムの保護
Windows7がインストールされたドライブ（通常はC）は「システムの保護」がデフォルトで有効なので復元ポイントは自動的に作成されます
スタートメニューから「コンピューター」を右クリックし「プロパティ」をクリック
※又は「コントロールパネル」－「システムとセキュリティ」－「システム」をクリック
左ウィンドウで「システムの保護」をクリック
