Microsoft blocks Windows 10 April Update for Intel SSD 600p Series

Microsoft is blocking some Intel SSDs from installing the April 2018 Update after discovering an incompatibility issue that causes performance and stability issues. In short, the problem was explained by Microsoft as: “When attempting to upgrade to Window 10 April 2018 Update select devices with certain Intel SSDs may enter a UEFI screen reboot or crash repeatedly.” Microsoft says that this issue has no workaround and that those that have attempted to update Windows 10 to the Windows 10 April 2018 Update should revert back to Windows 10 Fall Creators Update version 1709.

Unfortunately, the announcement by Microsoft fails to list what specific Intel SSD models are having issues with the OS update. We contacted Intel and discovered that the Intel SSD 600p Series of client drives that was first introduced to the market in 2016 is the most popular drive that is having issues.

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.
