Microsoft in a support document explains that the updates released today will allow computers running Windows 10 Creators and Fall Creators Update to show a notification of an improved privacy experience on upgrading the systems to Windows 10 April 2018 Update. If users are not sure what microcode recommendation should be used for their device, they should consult the device manufacturer before applying the update.
At the moment, Microsoft is busy with the rollout of Windows 10 April 2018 Update, the latest version of Microsoft's desktop operating system.
Meanwhile, if you have one of these Toshiba drives, and you've already upgraded to the Windows 10 April 2018 Update, then subsequently noticed a drop in your battery life, you may want to revert back to the previous version of Windows 10 (Fall Creators Update). The first is for Windows 10 Version 1703 and the second Windows 10 version 1709.
Microsoft is now working on a resolution that will allow the April 2018 Update on these devices in the near future.
