Great news! As we have recently wrapped up the Windows 10 Fall Creator’s Update (RS3) builds, we’ll soon begin rolling out our early RS4 builds to all Insiders in the Fast ring. This means that Insiders in the Fast Ring will get the same RS4 builds as those who chose to join Skip Ahead and have already started receiving RS4 builds. If you want to be one of the first to preview these early RS4 builds, make sure that you have selected the Fast Ring in your Windows Insider Program settings. (Go to Settings > Update & security > Windows Insider Program). Just remember: these Fast Ring releases may include more bugs and other issues than our other releases. If you prefer to wait a bit longer for Windows 10 Insider Preview features to get more stability, select the Slow Ring or Release Preview instead. 0340名無し~3.EXE2017/10/13(金) 11:38:07.07ID:1zvjRMW3 Issue: After upgrading from Build 16299.0 to 16299.15, you might lose all previously installed Feature-on-Demand (FOD) packages such as Windows Media Player, language features, etc. during the upgrade. If you upgraded to Build 16299.15 from an older build such as Build 16296 - you are not impacted. This issue occurs due to a bug in our servicing stack where the FOD packages are incorrectly “dead-ended”. When this happens, setup removes these “dead-ended” FODs during upgrade. By losing these FOD packages, you might experience a range of issues such as your email not syncing in the Mail app, different elements of UI not appearing in Settings or apps like Mail, font disappearing, Cortana not working correctly and the loss of Windows Media Player. To get out of this state: You will have to manually reinstall your missing FOD packages. There may be some cases where some missing FODs are automatically reinstalled, such as those tied to the languages associated with your profile. Other features may require command line operations to install. If you are missing Windows Media Player: You can add Windows Media Player by going to Settings > Apps > Apps & features, clicking on “Manage optional features” and then “Add a feature” and select Windows Media Player to install. Future upgrades to builds newer than Build 16299.15 shouldn’t remove the FODs that were reinstalled. 0341名無し~3.EXE2017/10/13(金) 23:02:40.68ID:mPtKd+cF Win10がまだ発売される前にInsider Programに参加してPreview版をつかっていた当時の 仮想マシン(VMware)を久しぶりに引っ張り出してきたら起動できなくなっていたので、 https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso から最新のISOをダウンロードして、新規の仮想マシンにクリーンインストールしたものの、 アクティベーションが通りません
