Announcing Windows 11 Insider Preview Build 22572宣布推出 Windows 11 预览体验计划预览版 22572-LaokNas网络技术笔记

Clipchamp is our new video editor focused on making video creation easy, fast, and fun. Clipchamp is equipped with all the basic tools you’d expect, like trimming and splitting, as well as more pro-style features like transitions and animated text. For real-time content capture, there are also built-in webcam and screen recorders.

Clipchamp’s video editing experience with the timeline.

But what really sets Clipchamp apart from other video editors is its timeline. Normally, this is an interface reserved for pros because it offers more control (and complication) than the everyday editor can handle. When it comes to Clipchamp, however, things are delightfully different. We’ve kept all the best parts of timeline editing — the flexibility, the ability to fine tune details — and done away with the rest. The result is a refreshingly simple video editing experience anyone can enjoy.

但真正使Clipchamp与其他视频编辑器区分开来的是它的时间线。通常,这是为专业人士保留的界面,因为它提供了比日常编辑器可以处理的更多的控制(和复杂性)。然而,当谈到Clipchamp时,事情却令人愉快地不同。我们保留了时间轴编辑的所有最佳部分 – 灵活性,微调细节的能力 – 并取消了其余部分。结果是任何人都可以享受的令人耳目一新的简单视频编辑体验。

The highlights don’t stop there — in Clipchamp, users will discover more unique offerings, like a stock library filled with more than a million royalty-free videos, audio tracks, and images that can be added to videos. There’s even an Azure-powered text-to-speech generator capable of creating voice overs in more than 70 languages. And, speaking of Microsoft integrations, Clipchamp also connects with OneDrive, meaning you can import files and save videos quickly and securely.

亮点并不止于此 – 在Clipchamp中,用户将发现更多独特的产品,例如一个库存库,其中包含超过一百万个免版税视频,音轨和可以添加到视频中的图像。甚至还有一个 Azure 支持的文本到语音转换生成器,能够以 70 多种语言创建语音。而且,说到Microsoft集成,Clipchamp还与OneDrive连接,这意味着您可以快速安全地导入文件并保存视频。

To start creating your own videos, look for Clipchamp in the Start menu on your PC.

Search highlights in Windows 11

Starting early next week, we will begin rolling out an update for Search in Windows 11 that highlights interesting moments in time. Search is right there on your taskbar—your window to discover what’s trending online, in the world, and in your organization. Of course, you can still type to start searching for your apps, files, settings, and quick answers on the web.

从下周初开始,我们将开始在Windows 11中推出搜索更新,以突出显示有趣的时刻。搜索就在任务栏上,这是一个窗口,用于发现在线、世界和组织中的趋势。当然,您仍然可以键入以开始在 Web 上搜索您的应用、文件、设置和快速答案。

The search box in Start and Search will periodically update with content, including fun illustrations, that help you discover more, be connected, and stay productive. These hints in the search box give you a sneak peek into what to expect in search home.


Search highlights will present notable and interesting moments—like holidays, anniversaries, and other educational moments in time both globally and in your region. You’ll find rich, bold content in search home that highlights what’s special about today.

To dig deeper, you can explore additional content in search home related to today’s moment and daily content like word of the day, Microsoft Rewards offers, trending searches, and more. Each day features something different to learn about! The left side of search home also shows an extended list of your recently launched apps, files, settings, and websites to help you get back to what you were doing last.

若要深入挖掘,你可以在搜索主页中浏览与当前时刻和每日内容相关的其他内容,如每日字词、Microsoft 奖励产品/服务、热门搜索等。每天都有不同的东西需要学习!搜索主页的左侧还显示最近启动的应用、文件、设置和网站的扩展列表,以帮助你返回到上次执行的操作。

You have control over the search highlights experience where if you prefer not to see this, you can turn it off or back on in Settings > Privacy & security > Search settings and toggling “Show search highlights”. For organization administrators, there are additional controls available in the M365 admin center. You can learn more about those policies here: Policy CSP – Search.

搜索亮点也即将进入Windows 10搜索框,您可以在其中获得搜索框和搜索主页的相同更新。请继续关注即将发布的博客文章中的详细信息,我们将在发布预览频道中开始在 Windows 10 上使用预览体验成员试用此体验。

This feature will begin rolling out early next week and won’t be available to all Insiders right away as we plan to monitor feedback and see how it lands before pushing it out to everyone.

Known issues


  • Users running Windows 10 who try to upgrade directly to build 22563 or higher in the Dev Channel may encounter an install failure with error code 0x8007007f. To bypass, please join the Beta Channel, install the offered Windows 11 build there, and then switch to the Dev Channel to receive the current Dev Channel update. This issue is understood and will be fixed in an upcoming build.

[Tablet-optimized taskbar]

  • The taskbar doesn’t always automatically collapse after launching an app or tapping outside of the expanded taskbar on 2-in-1 devices.
  • Some areas of the OS are not yet tracking the height of the expanded taskbar on 2-in-1 devices so you may see overlapping components, such as Widgets overlapping with the taskbar.

[File Explorer]

  • Opening suggested results shown while entering search terms in File Explorer’s search box may not work.
  • We’re working fixing issues regarding icon sizing, visual bugs, and text clipping in the flyout showing OneDrive storage.


  • Sometimes when pinning from the Feed, the pinned widget is placed at the top instead of below other pinned widgets. If this happens this will autocorrect within 30 minutes, moving the recently pinned widget to the expected default location. Or you can sign out of your Widgets board and immediately signing back in should correct the problem.
  • After rearranging widgets in the widgets board, some users experience problems with widgets in the pinned section rendering incorrectly. If this happens, signing out of your widgets board and immediately signing back in should correct the problem.


  • The Clock app does not yet update Windows Focus state when configuring focus sessions within the app. This will be addressed in a future app update.


  • Narrator natural voices sounds garbled and will not read out text accurately. This happens when doing quick navigation, typing or pitch changes. As a workaround, you can switch back to the older voices such as Microsoft David, Mark or Zira.

[Live captions]

  • Certain apps in full screen (e.g., video players) prevent live captions from being visible.
  • Certain apps positioned near the top of the screen and closed before live captions is run will re-launch behind the live captions window positioned at top. Use the system menu (ALT + Spacebar) while the app has focus to move the app’s window further down.
  • The very top of maximized apps (e.g., title bar window management buttons) can’t be reached with touch while live captions is positioned at the top.

[Task Manager]

  • Some tooltips do not accurately display the preferred visual setting when Task Manager is configured for dark mode.

Announcing the March 2022 Bug Bash

From March 16th to March 22nd, we will be having a Bug Bash covering our latest Insider Preview builds – keep an eye on the Feedback Hub under the Announcements section where we will be posting more details closer to the date. Insiders who participate in the Bug Bash by completing Quests and filing feedback during this time will be awarded a Bug Bash badge in Feedback Hub.

About the Dev Channel [Updated!]

The Dev Channel receives builds that represent long lead work from our engineers with features and experiences that may never get released as we try out different concepts and get feedback. It is important to remember that the builds we release to the Dev Channel should not be seen as matched to any specific release of Windows and the features included may change over time, be removed, or replaced in Insider builds or may never be released beyond Windows Insiders to general customers. For more information, please read this blog post about how we plan to use the Dev Channel to incubate new ideas, work on long lead items, and control the states of individual features.

These aren’t always stable builds, and sometimes you will see issues that block key activities or require workarounds. It is important to make sure you read the known issues listed in our blog posts as we document many of these issues with each flight.

Build numbers are higher in the Dev Channel than the Windows 11 preview builds in the Beta and Release Preview Channels. You will not be able to switch from the Dev Channel to the Beta or Release Preview Channels without doing a clean install back to the released version of Windows 11 currently.

The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
