  • MS acknowledges blue screen bug when installing the Aug or Sept cumulative update on Win10 version 2004 Lenovo machines

    Mayank Parmar at Windows Latest has the rundown on Microsoft’s latest confession:

    In a new support document that was quietly published over the weekend, Microsoft has warned that it has observed a number of other critical errors caused by KB4568831 or newer, which also includes the September 2020 patch…

    The problem appears to have been caused by a compatibility issue between Windows 10’s cumulative update, UEFI settings, and Lenovo’s Vantage app. With a cumulative update, Microsoft made a change that restricts how processes can access PCI device configuration and feature in UEFI could trigger this behaviour, which causes a Blue Screen.

    KB 4568831 is the Win10 version 2004 “optional, non-security, C/D/E Week” preview patch released in late July.

    Yes, the bug’s been around for six weeks. No, it hasn’t been fixed. But there is a manual workaround, discussed in Parmar’s article.

    Tell me again how version 2004 is ready for prime time.
