富士通のLIFEBOOK AH45/XをWindows11にアップグレード

富士通のLIFEBOOK AH45/XをWindows11にアップグレードした。
途中で出たエラー(ErrorCode: 0x8007051A)の原因がわからなくて、あれこれ調べて３０時間くらいかかった。

Microsoft が配っている「SetupDiag.exe」の結果などは記事の最後に掲載。

結論を先に書くと、「C:\Windows\System32\drivers」の中にある「PxHlpa64.sys」を削除して、関連するレジストリキーの値を空にしたら解決した。

マカフィーの削除、Windows Defender の停止、Bios のアップデートなど色々やったが全部無駄だった。

★解決の手順

(1)「PxHlpa64.sys」を削除。「C:\Windows\System32\drivers」の中にある。

これだけだとWindows11をインストールするための Win11_25H2_Japanese_x64_v2.iso をマウントできなくなってしまう。PxHlpa64.sys はDVDなどへの書き込みで使われる Corel 社製のドライバらしい。

(2)ISOをマウントするときにPxHlpa64.sysが参照されないように、レジストリキー「HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e965-e325-11ce-bfc1-08002be10318}」の「LowerFilters」の値を「PxHlpa64」から空欄に変更。(中身を削除。)

これで Windows11 のインストール用 iso ファイルをマウントできるようになる。

(3)CPUの検査に引っかからないように次のレジストリキーを作成して設定。

レジストリキー「HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup」
値の名前「AllowUpgradesWithUnsupportedTPMOrCPU」
型「REG_DWORD（DWORD 32ビット)」
値の内容「1」

これをやらないとCPUが未対応です、みたいなエラーが出る。

(4)次いで Widnows 11 の ISO ファイルをダウンロードする。

「x64 デバイス用 Windows 11 ディスクイメージ (ISO) をダウンロードする」からダウンロード。

マイクロソフトのページ

(5)ダウンロードした ISO ファイルをマウントして「setup.exe」を実行する。

この時、更新プログラムのダウンロードは、Windows 11 のインストール時には行わないようにする。

そうしないとエラーが出る。
