"When attempting to upgrade to the Windows 10 April 2018 Update, select devices with Intel SSD 600p series or Intel SSD Pro 6000p series may crash and enter a UEFI screen after reboot," said Microsoft earlier this month. "Microsoft is working with OEM partners and Intel to identify and block devices with Intel SSD 600p series or Intel SSD Pro 6000p series from installing the April 2018 Update due to a known incompatibility that may cause performance and stability issues."
Thankfully, Microsoft was able to resolve the issue by working with Intel and is issuing KB4100403, which prevents a PC with the above-mentioned SSDs from repeatedly entering the UEFI screen after a system restart. Interestingly, another SSD-related issue that wasn't widely reported is also addressed in KB4100403, and it pertains to specific Toshiba SSDs (Toshiba XG4 Series, Toshiba XG5 Series, Toshiba BG3 Series). In this case, the Windows 10 April 2018 Update resulted in systems with these SSDs experiencing reduced battery life.
KB4100403 bumps the Windows 10 April 2018 Update (version 1803) to build 17134.81.
Microsoft is cautioning that users with the specified Intel and Toshiba SSDs should simply sit tight until it starts pushing the Windows 10 April 2018 Update to specific device models. But if you have an Intel SSD and are adamant about upgrading to the newest build (perhaps to gain access to the new features introduced with the April 2018 Update), you can manually check for updates starting May 25th to get the newest build. Toshiba SSD owners can either manually update now or wait until the update is pushed out automatically during June's Patch Tuesday.
In addition to the fixes for SSDs, Microsoft says that KB4100403 tackles the following concerns:
- 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.
- Addresses additional issues with updated time zone information.
- Addresses an issue where closed-caption settings are preserved after upgrade.
- Addresses a reliability issue that may cause Microsoft Edge or other applications to stop responding when you create a new audio endpoint while audio or video playback is starting.
- Addresses an issue that may cause Windows Hello enrollment to fail on certain hardware that has dGPUs.
- Addresses an issue with power regression on systems with NVMe devices from certain vendors.
The Windows 10 April 2018 Update was initially released on April 30th, just barely making the cutoff to truly be considered a "true" April software update.
