ハイライト:
A gradual rollout distributes a release update over a period of time, rather than all at once. This means that users receive the updates at different times, and it might not be immediately available to all users.
[Improved Windows Search]
New! Finding your documents, photos, and settings across Windows 11 is easier on Copilot+ PCs with improved Windows Search, powered by semantic indexing models along with traditional lexical indexing. Whether it’s searching in File Explorer, in the Windows Search on your taskbar, or in Settings – just type what’s on your mind to find it on your Copilot+ PC. You no longer need to remember file names, exact words in file content, or settings names. Searching for settings like “change my theme” will work within the Settings app for now. Thanks to the power of the 40+ TOPS NPU onboard Copilot+ PCs, these search improvements work even when you’re not connected to the internet. For more info, see semantic search on Copilot+ PCs. Available on Snapdragon-powered Copilot+ PCs, with support for AMD and Intel-powered Copilot+ PCs coming soon.
New! Locating your photos stored and saved in the cloud is getting simpler on Copilot+ PCs You can use your own words in the search box at the upper-right corner of File Explorer like “summer picnics”. In addition to photos stored locally on your Copilot+ PC, photos from the cloud will now show up in the search results together. Exact matches for your keywords within the text of your cloud files will also show in the search results. You can try this experience out today with your personal OneDrive when signed in with your Microsoft account and connected to the internet. To learn more, see semantic search on Copilot+ PCs. Available on Snapdragon-powered Copilot+ PCs, with support for AMD and Intel-powered Copilot+ PCs coming soon.

New! A new experience to improve the discoverability of the emoji and more panels in Windows 11 with the introduction of a new system tray icon on the taskbar. This change will initially be available to a small group of devices.

Supported languages include Arabic, Bulgarian, Czech, Danish, German, Greek, English, Estonian, Finnish, French, Hindi, Hungarian, Italian, Japanese, Korean, Lithuanian, Norwegian, Dutch, Polish, Portuguese, Romanian, Russian, Slovak, Slovene, Spanish, and Swedish.
[Voice access]

Fixed: Opening certain apps after a password change could result in an unexpected lockout if the account lockout policy is enabled.

This fix stops devices from encountering this issue in the future. If you have already encountered this issue, you can manage extra boot entries in the Boot section of System Configuration (msconfig).
[Color profile]

[Settings] Fixed: For Japanese users, the name displaying at the top of Settings > Accounts shows First Name Last Name instead of Last Name First Name.
[Deprecation]
Suggested actions, which appear after you copy a phone number or future date in Windows 11, are now deprecated and being removed.

[Task manager] Task Manager will now calculate CPU usage differently for Processes, Performance, and Users pages. It will use standard metrics to display CPU workload consistently across all pages and align with industry standards and third-party tools. To ensure backward compatibility, an optional column named CPU Utility is available (hidden by default) on the Details tab, showing the previous CPU value from the Processes page.
[Cryptography] Fixed: This update addresses an issue that was impacting Credential Roaming, preventing certificates and keys from being roamed into Active Directory and made available on users' machines.

更新プログラムには以下の3点の既知の不具合が存在します。
RobloxApplies to: All users
Symptoms
We’re aware of an issue where players on Arm devices are unable to download and play Roblox from the Microsoft Store on Windows.
Workaround
Roblox is working on a resolution to address this issue. Please refer to the Roblox support site for updates. Until the resolution is available, players on Arm devices can play Roblox by downloading the title directly from www.Roblox.com.
CitrixApplies to: IT Admin
Symptoms
Devices that have certain Citrix components installed might be unable to complete installation of the January 2025 Windows security update. This issue was observed on devices with Citrix Session Recording Agent (SRA) version 2411. The 2411 version of this application was released in December 2024.
Affected devices might initially download and apply the January 2025 Windows security update correctly, such as via the Windows Update page in Settings. However, when restarting the device to complete the update installation, an error message with text similar to “Something didn’t go as planned. No need to worry – undoing changes” appears. The device will then revert to the Windows updates previously present on the device.
This issue likely affects a limited number of organizations as version 2411 of the SRA application is a new version. Home users are not expected to be affected by this issue.Workaround
Citrix has documented this issue, including a workaround, which can be performed prior to installing the January 2025 Windows security update. For details, see Citrix’s documentation.
Microsoft is working with Citrix to address this issue and will update this documentation once a resolution is available.

We're aware of an issue with the Microsoft Copilot app affecting some devices. The app is unintentionally uninstalled and unpinned from the taskbar.
Note: This issue has not been observed with the Microsoft 365 Copilot app.
