今天，微軟推送了Windows 10 20H1跳躍預覽版18865系統更新，本次更新主要是穩定性和Bug修復提升，并未帶來明顯的新功能，請記住 - 這些構建來自20H1開發分支。我們在20H1工作的一些事情需要更長的準備時間。
重要提示：正如開發周期早期的構建一樣，這些構建可能包含可能對某些人來說很痛苦的錯誤。如果你乘坐這個航班，如果沒有在你的電腦上進行干凈安裝并重新開始，你將無法切換回快速或慢速環。
如果您正在尋找一個完整的外觀，請看Inside環有什么內容 - 轉到Flight Hub。您還可以在此查看我們的其他文檔，包括作為當前開發周期的Insider航班一部分的新功能和更新的完整列表。

Known issues
Launching games that use anti-cheat software may trigger a bugcheck (GSOD).
Some Realtek SD card readers are not functioning properly. We are investigating the issue.
Creative X-Fi sound cards are not functioning properly. Creative has released updated drivers for some affected X-Fi sound cards.
Please refer to Creative’s website for details on your particular hardware and any available updates.
Known issues for Developers
If you install any of the recent builds from the Skip Ahead and switch to either the Fast ring or the Slow ring, optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.
