今天，微软向快速预览通道用户推送了Windows 10 20H1 18875更新，微软表示，目前正在将20H1版本从跳跃预览通道提前到快速预览通道，部分快速预览通道的用户会收到与跳跃预览通道相同的版本推送。
本次微软面向Windows 10 20H1版本推送的新更新主要针对东亚地区的IME输入法进行更新，包括新的日语输入法、新的简体中文输入法和新的繁体中文输入法。
新的日语IME使用更加安全稳定，具有更高的游戏兼容性。新的简体中文IME支持拼音和五笔，而繁体中文IME支持拼音、仓颉和快速输入，微软为候选窗口和设置页面添加了更加清晰的界面。用户可以在设置中添加新的IME键盘。
以下为Windows 10 20H1 18875快速预览版的更新日志：
一、PC的一般更改，改进和修复：
修复通过触摸键盘与设备交互然后切换键盘布局出现的屏幕冻结问题；
修复设置在最近的几个版本中偶尔崩溃问题；
修复导致部分内测用户重启后被要求重新设置设备问题；
修复设置>系统>存储>临时文件中某些文字中文或日文出现乱码问题；
针对时间轴进行更改，如果用户搜索时选择不加入时间轴则在时间轴中不显示加入的搜索结果；
修复最大化触摸键盘可能导致某些应用程序闪烁的问题；
修复将照片磁贴固定在开始菜单出现的电池意外消耗问题，及时应用没有打开也会触发这一问题。
二、已知问题：
此前，旧版游戏反作弊软件在更新到最新的19H1预览版后可能导致电脑崩溃，目前微软正在与合作伙伴合作通过修复程序更新游戏，大多数游戏都已经发布了新的补丁防止电脑再遇到这一问题，为了减少这一问题出现，请在更新系统前确保游戏是最新的版本。另外，20H1版本也可能出现类似问题；

收到部分内测用户反馈，在下载Windows 10 20H1 18875版本遇到0xca00a000错误，目前正在处理这一问题，如果遇到这一问题请向微软反馈。
三、开发人员已知问题：
如果从快速更新切换到慢速更新或发布预览更新，启动开发人员模式等可选内容会失败，必须在快速预览版才能添加/安装/启动可选内容，因为这些内容只针对特定版本才可以使用。

IMPORTANT: As is normal with builds early in the developmentcycle, these builds may contain bugs that might be painful for some. If youtake this flight, you won’t be able to switch Slow or Release Preview ringswithout doing a clean-install on your PC. If you wish to remain on 19H1, pleasechange your ring settings via Settings > Update & Security > WindowsInsider Program *before* taking this flight. See this blogpost for details.
Ifyou are looking for a complete look at what build is in which Insider ring –head on over to Flight Hub. Youcan also check out the rest of ourdocumentation here including a complete list of new featuresand updates that have gone out as part of Insider flights for the currentdevelopment cycle.
What’s new in Build18875
East Asian Microsoft Input MethodEditor (IME) Improvements:
The New Japanese IME is now available to all Insiders in Fast!
During19H1, we announced we were working on a new JapaneseIME. We got a lot of great feedback, and the IME was taken offlinefor a time while we worked on improving the experience based on what you’d toldus. Today the IME – now more secure, more stable, with improved gamecompatibility, and more – is once again available for all Insiders startingwith this build. If you speak Japanese, please take some time to evaluatehow it feels to use the IME (with all the improvements) for daily usage,and let us know what youthink! If you already were using the Japanese IME, you’ll automatically havethe new one when you install this build – if you weren’t already using the Japanese IME, you can add it by going to Languages Settings and adding Japanese to the list.
New IMEs are available for Simplified and Traditional Chinese!
Justlike the Japanese IME above, we’ve been working on refining your Chinese typingexperience, and are happy to share that we have new versions ofthe Chinese Simplified IMEs (Pinyin and Wubi), as well as the ChineseTraditional IMEs (Bopomofo, ChangJie and Quick). We’ve improved the securityand reliability by redesigning how they work with applications. You’ll alsonotice we’ve added a cleaner interface for the candidate window andsettings pages. Improved and renewed settings of the IMEs are available in theSettings app. If you’re using one of the IMEs and you’d like to check it out,the fastest way there is to right-click the IME mode indicator in the taskbarand select Settings (you can get there from the Language Settings page byclicking the language, and going into options). Looking forward tohearing what you think about it!
General changes,improvements, and fixes for PC
We fixed an issue that could result in a freeze on the lock screen if you interacted with the touch keyboard and then switched keyboard layouts.
We fixed an issue resulting in Settings sporadically crashing in the last few builds.
We fixed an issue resulting in some Insiders being prompted to setup their device after every reboot.
We fixed an issue resulting in some of the text under Settings > System > Storage > Temporary Files being unexpectedly garbled in Chinese and Japanese.
We’ve made a change in Timeline for keyboard-only users, so if you’re doing a search and haven’t opted in, you’ll no longer have to tab past the opt-in text before you can get to the search results.
We fixed an issue that could cause certain applications to flicker if they were maximized and you launched the touch keyboard.
We fixed an issue where, if the Photos tile was pinned to Start, it could potentially result in unexpected battery drain as the tile animation would trigger even if Start wasn’t open.
Known Issues
There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds, and will work to minimize the likelihood of these issues in the future.
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 forDevelopers
If you install builds from the Fast ring and switch to either the Slow ring or the Release Preview 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.
