更新プログラムには以下の2件の既知の不具合が存在します。
| 症状 | 回避策 |
|---|---|
| プロビジョニングパッケージが正常に動作しないことがある。Windowsが部分的にしか構成されず、Out Of Box Experienceが終了しなかったり、予期せず再起動したりする可能性がある。 | Windows 11 Version 22H2にアップグレードする前に、Windowsデバイスをプロビジョニングすることができれば、この問題を防ぐことができる。 |
| 複複数の大きなGBファイルのコピーに予想以上の時間がかかることがある。サーバーメッセージブロック(SMB)経由でネットワーク共有からWindows 11, Version 22H2にファイルをコピーする場合に発生しやすいものの、ローカルファイルのコピーも影響を受ける可能性がある。 | この問題を軽減するために、キャッシュマネージャー(バッファードI/O)を使用しないファイルコピーツールを使用することができる。これは、以下に挙げる組み込みのコマンドラインツールを使用する。
現在、解決に向けて取り組んでおり、今後のリリースで最新情報を提供する予定。 |
