KB4100403

Earlier today, Microsoft released cumulative update KB4100403 that fixes several bugs, including the issues some users reported with Intel and Toshiba solid-state drives (SSDs).

Users reported these issues after updating to the latest version of Windows 10, the April 2018 Update —also known as version 1803.

Microsoft fixes Windows 10 April 2018 Update issues

Owners of computers using with Intel SSD 600p Series, Intel SSD Pro 6000p Series, Toshiba XG4 Series, Toshiba XG5 Series, and Toshiba BG3 Series reported various problems.

More specifically, Windows PCs using Intel SSDs would often crash and enter a UEFI screen after reboot, while users of Toshiba SSDs reported lower battery life and SSD drives becoming very hot.

Many users —who still had access to a working Windows OS— were forced to downgrade back to the previous version, the Fall Creators Update, while the rest had to reinstall Windows from scratch.

Microsoft became aware of the issues after a week and worked with OEMs to halt the deployment of the April 2018 Update to any devices using the affected Intel and Toshiba SSD models [1, 2].

The company promised a fix for early June, but Microsoft engineers rolled one out today, via KB4100403.

Other issues also fixed

This update is available via the normal Windows Update service, or users can download it from the Microsoft Update Catalog.

KB4100403 is an update only available for Windows 10 and Windows Server 2016 version 1803, and besides the Intel and Toshiba SSD issues, it also patched the following bugs:

⌁    Addresses an issue in Internet Explorer that might cause communication between web workers to fail in certain asynchronous scenarios with multiple visits to a web page.
