Depending on which device you have, your phone may be in this stuck state for 20-30 minutes, but it will eventually progress to the Lock screen. There is no permanent impact from these 2 bugs, just an unexpectedly long boot time. Please don’t reset your device! It’ll take longer to reset the device than it will to wait for the boot cycle to complete.

              • The Desktop App Converter Preview (Project Centennial) will fail to run on the Windows 10 Insider Preview Build 14366. If you are a developer utilizing the converter tool to convert your desktop app to UWP, we suggest skipping Build 14366 or switching to the Slow ring until we can fix this issue.
              • If you click on a file download link outside of Microsoft Edge, sometimes Edge will open a tab and close it without doing anything. The workaround is to go to the Download pane and start the download there by clicking “Save” or “Save As”.

              Build 14361 既知の問題

              • If you have a French Windows 10 Insider Preview build installed on your PC, you will not receive Build 14361. There is an issue with the French translation process in this build that would revert a lot of text that was used to be shown in French back to English. So we have chosen not to release this build to Insiders whose base build is French. If your base build is not French and you have a French Language Pack installed – you will still be able to install the new French language pack on top of this build, but this issue will also impact you.
              • Text prediction using the Japanese IME will freeze your PC. To avoid this issue and continue using the Japanese IME, we recommend turning off text prediction. You can do this by right-clicking IME mode icon “A” or “あ” in systray and selecting “Properties”, clicking “Advanced”, and navigate to the “Predictive Input” tab and check off “Use predictive input system”. You can turn on prediction feature again by checking it on.
              • Navigating to the Privacy pages in Settings app will crash the Settings app and prevent you from adjusting your privacy settings. Your privacy settings already set will remain intact after updating to this build. If this is a blocker for you, you can move to the Slow ring until this bug is fixed or be sure to set your privacy settings before updating to this build.
              • If you click on a file download link outside of Microsoft Edge, sometimes Edge will open a tab and close it without doing anything. The workaround is to go to the Download pane and start the download there by clicking “Save” or “Save As”.
              • For certain languages, such as Chinese or Portuguese (Brazil), you will not be able to launch Start while an app is installing.

                • Previously installed extensions for Microsoft Edge may not work for around 15 minutes after your first sign-in. A work around for this is to manually re-install each extension from the Store.
                • In some cases, the new Cortana features highlighted above may not work. Restarting your PC should fix the issue and get the features working.
                • Using the keyboard to navigate in certain Store apps like Netflix or Tweetium does not work. You will need to use your mouse.

                • Feedback Hub is not localized and the UI will be in English (U.S.) only, even with language packs installed.
                • Feedback Hub takes about 20-30 minutes after updating to this build to download and populate itself if launched from Start. If you launch Feedback Hub from All apps – it will force the app to hydrate.
                • Symantec products such as Norton Antivirus and Norton Internet Security are causing PCs to bluescreen (bug check).
                • The QQ app from Tencent crashes. We’re working on a fix for the issue.
                • If you are using a non-English keyboard, you can’t accept Bash prompts.
                • We are investigating an issue where if you’re running Insider Preview builds in certain languages, the All apps list on Start appears empty. A workaround for this is to use search to launch apps.
                • We have reduced the number of instances where boxes are seen when entering emoji. You may still see them in some text fields – we’re working on it! 

                Build 14332 既知の問題

                • We’re adding a built-in network speed test under Settings > Network & Internet > Status however it doesn’t work just yet. The UI is there but we still have some backend work to get it turned on and working.
                • Feedback Hub is not localized and the UI will be in English (U.S.) only, even with language packs installed.
                • Feedback Hub takes about 20-30 minutes after updating to this build to download and hydrate itself.

                • Playing music in the Groove Music within 2 minutes after logging into your PC will result in 0xc10100ae playback errors. If you wait more than 2 minutes after logging in to play music in Groove Music you will avoid this issue.
                • You may see square boxes in certain apps when using some of the new emoji – we’re still getting things set up, this will be resolved in a future build.
                • We are continuing to make changes to our extension datastore schema in Microsoft Edge. As a result, after updating to this build any extensions installed will be removed. You can reinstall these extensions to get them back.
                • If you are using a non-English keyboard, you can’t accept Bash prompts.
                • We are investigating an issue where if you’re running Insider Preview builds in certain languages, the All apps list on Start appears empty. A workaround for this is to use search to launch apps.

                • We are aware of situations in which Groove Music will crash on launch at the splash screen and working to get a fix out soon. As a workaround, you can use Groove Music online.
                • Playing music in the Groove Music within 2 minutes after logging into your PC will result in 0xc10100ae playback errors. If you wait more than 2 minutes after logging in to play music in Groove Music you will avoid this issue.
                • In Microsoft Edge, some large downloads may appear to get stuck at 99% completion. You can work around this issue by renaming the file in your downloads after closing Microsoft Edge. This workaround skips security checks on the file, so it should be used only with files from a trusted source.
                • If you have BitLocker/Device Encryption enabled and try go back to a previous Insider Preview build via “Go back to an earlier build” under Settings > Update & security > Recovery – the app will crash and you will be unable to rollback. To work around this issue, disable BitLocker/Device Encryption and try again.
                • Settings will crash if you try to pin one of the pages to Start, resulting in page not being pinned
                • You may see square boxes in certain apps when using some of the new emoji – we’re still getting things set up, this will be resolved in a future build.
                • If you upgraded from 14316, you may see stuck apps in the Store. Those apps will also be duplicated in Start’s all apps list (one real, one pending). To resolve this: 1) Start downloading some other app. 2) Pause the download, then go to the downloads and update view. 3) Click the "Resume All" button. Once everything has downloaded, the issue should be resolved.

                • The Visual Studio emulator for Windows 10 Mobile and Hololens will fail with “An authentication error has occurred. The Local Security Authority cannot be contacted”. If you are a developer and require the emulator for building apps, we suggesting moving to the Slow ring and skipping this build until we can fix this issue.
                • We continue to investigate issues with Narrator and other screen reader apps that make them unable to read selected text in the Feedback Hub, Cortana, and other apps.
                • In Microsoft Edge, some large downloads may appear to get stuck at 99% completion. You can work around this issue by renaming the file in your downloads after closing Microsoft Edge. This workaround skips security checks on the file, so it should be used only with files from a trusted source.
                • In some cases, attempting to turn on Developer Mode on may crash the Settings app. If this happens, the workaround is to use these steps here to enable Developer Mode.
                • Some apps notifications may only show the icon – however the full text of the notification will be visible within Action Center.
                • [ADDED 4/7] We are investigating an issue where UWPs do not appear on the taskbar when minimized. When this happens, the app icons don’t show up on the taskbar and they are also not shown in ALT + Tab or Task View. The only way to maximize these apps is via Task Manager. Additionally, you can try restarting  Explorer.exe from Task Manager to get out of this state.

                • We are aware of issues with Narrator and other screen reader apps being unable to read the menu options in the Feedback Hub, as well as issues with Narrator not reading selected text in the Feedback Hub, Cortana, and other apps. We’re working diligently to fix these bugs as soon as possible and apologize to Insiders impacted by this.
                • If you use Hyper-V and have a Virtual Switch configured for your network adapter, you may see an error indicator (red-colored “X”) for your network adapter in the notification area of your taskbar. The error indicator is incorrect and your network adapter should continue to work just fine.
                • On some PCs with TPM chips, such as the ASUS Zenbook UX31, you may experience glitchy audio and jumpy movement when using the trackpad due to the “tpm-maintenance” task running constantly in the background instead of once per boot-up like it should. As a temporary workaround, you can disable the tpm-maintenance task in Task Scheduler (under \microsoft\windows\tpm).
                • PCs that use Windows Hello or a PIN to sign-in to the device will launch the Microsoft Passport service. When this happens, there is an issue in this build where Bluetooth will then repeatedly scan for devices. This causes a few issues on the PC including reduced battery life, audio glitches, responsiveness issues with Bluetooth keyboards and mice, a decrease in Wi-Fi throughput on Wi-Fi/Bluetooth combo chipsets, and a decrease in throughput for Bluetooth file transfers. As a workaround, you can disable the Microsoft Passport (NgcSvc) service by opening an elevated Command Prompt, run “reg add HKLM\System\CurrentControlSet\Services\NgcSvc /v Start /t REG_DWORD /d 0x4 /f” and then reboot. However, you will not be able to use Windows Hello or a PIN to sign-in to your device. The service will be re-enabled again when you update to the next build.
                • After upgrading to this build from Build 14291, attempting to connect to a Miracast receiver the connection will fail. The workaround to get out of this state is to go to this registry key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\
                • Parameters” and select “StandaloneDhcpAddress” and change the value from “192.168.173.1” to “192.168.137.1” (value type is REG_SZ). Then retry the connection to the Miracast receiver.
                • We are seeing reports of some apps such as QQ crashing. We are currently investigating, and this bug may also impact older apps such as Windows Live Mail and Expression Encoder 4.

                • We continue to investigate an issue in which some Surface Pro 3, Surface Pro 4, and Surface Book devices experience a freeze or hang and all input such as keyboard/trackpad and touch do not work. The workaround is to hold down the power button to force the device to hard-reboot.
                • Your PC may freeze when plugging in an Xbox One or Xbox 360 controller and other gamepads in this build.
                • If you use Hyper-V and have a Virtual Switch configured for your network adapter, you may see an error indicator (red-colored “X”) for your network adapter in the notification area of your taskbar.

                • If you have Kaspersky Anti-Virus, Internet Security, or the Kaspersky Total Security Suite installed on your PC there is a known driver bug that prevents these programs from working as expected in builds from the Development Branch. We are partnering with Kaspersky to fix this issue for a future release, but at this time there are no known workarounds. While this issue is present, we recommend using Windows Defender or another third party anti-virus product of your choice to remain protected.

                • Connectivity to older Wi-Fi networks using the WEP encryption security method may be broken. WEP is an insecure method for protecting your Wi-Fi connection but a small percentage of Windows users still use it. A workaround would be to configure your wireless routers to use WPA or WPA2 or wait for the next Insider flight when this is fixed.

                • If you choose “Reset This PC” under Settings > Update & Security > Recovery – your PC will be in an unusable state. There is no workaround if your PC gets into this state and you will need to reinstall Windows. This issue will be fixed in the next build. You can still rollback to the previous build if for some reason this build doesn’t work out for you. This bug also existed in Build 14251 so please avoid resetting your PC on these builds.
                • You might see a WSClient.dll error dialog after logging in. We’re working on a fix for this but as a workaround, you can run the following in Command Prompt with administrative rights: schtasks /delete /TN “\Microsoft\Windows\WS\WSRefreshBannedAppsListTask” /F. This issue will be fixed in the next build.
                • The front-facing camera is unusable on PCs with Intel RealSense resulting in being unable to use Windows Hello or any other apps that utilize the front-facing camera.
                • After logging in to your PC, you may hit a UI issue in which Airplane Mode will incorrectly show as “on” even though your PC’s Wi-Fi is powered on. This is due to a timing issue between how the UI communicates and waits for the underlying platform to respond. The UI for Airplane Mode essentially does not wait long enough for the device’s physical radios to power on before reporting the current state. You can toggle the Airplane Mode on and off to get Airplane Mode back to showing the correct state.

                • Some PC games will crash switching from windowed mode to full screen, upon game resolution change, or upon launch due to a bug in Windows graphics stack. We have observed this with The Witcher 3, Fallout 4, Tomb Raider, Assassin's Creed, and Metal Gear Solid V but it may occur with other titles as well.
                • With this build (and with the last build), applications such as Narrator, Magnifier, and third-party assistive technologies may experience intermittent issues or crashes. If you rely on screen readers or other software, you should not use this build. This issue will be fixed with the next build.
                • You might see a WSClient.dll error dialog after logging in. We’re working on a fix for this but as a workaround, you can run the following in Command Prompt with administrative rights: schtasks /delete /TN "\Microsoft\Windows\WS\WSRefreshBannedAppsListTask" /F

                • When copying, deleting, or moving files there will be no progress dialog shown. The file action will complete without intervention. This can cause confusion when acting on large files or directories.
                • With this build, application defaults for some applications will be reset. Music & Video will default to Windows Media Player. This can be reconfigured opening Cortana or Search and searching for “Choose default apps by file type” to open the correct settings page.
