"Ever since it launched Windows 10, Microsoft has rolled out updates in stages. First, updates roll to people in the Fast Ring of the Windows Insider program, then the Slow Ring and the Release Preview Ring. Then, when a version drops, you can typically download it directly from Microsoft’s website if you wish. Over time, the company deploys the patch to everyone, provided that it doesn’t detect a fundamental incompatibility in your system hardware. One such incompatibility appears to have raised its head — and it’s a bit of an odd one, at that. According to Microsoft, Windows 10 April 2018 isn’t compatible with Intel’s SSD 600p or SSD Pro 6000p, and attempting to update the OS on a system that uses this storage solution may cause it to hang."
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.
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. If you have encountered this issue, follow the steps to reinstall the previous operating system (Windows 10, version 1709).
