  • There’s a fix for the bluescreen on the second March cumulative update for Win10 1809 – KB 4490481

    Remember the bluescreens many people reported after installing the second March cumulative update for Win10 1809, KB 4490481? For many people, installing the cumulative update results in a System Service Exception error when you restart. (To add to the confusion, the second cumulative update for March was released on April 2.)

    I’ve never seen an acknowledgment of the bug, even though I’ve seen lots and lots of reports. When Microsoft says it’s going to start documenting all of the significant bugs in cumulative updates, I’m still skeptical — and this is one of the prime examples.

    On Sunday morning, an enterprising (and bright!) fellow on the My Digital Life forum, max1, posted a fix. Ends up that the bluescreen is triggered if you have certain Media Center fonts on your Win10 1809 machine. (Media Center doesn’t ship with Win10. As for why anyone would want it… that’s a discussion for another time.)

    I have no idea how max1 figured it out, but reports from all over say it fixes the bluescreen. I first saw the report on Sunday evening, here on AskWoody, from an anonymous poster. Overnight, Martin Brinkmann posted confirmation on ghacks.

    There are four fonts you have to take off of your system. You can futz with the registry (Brinkmann has the instructions) or you can create a .reg file following the instructions from our anonymous poster:

    Copy the following into a text file, rename it with .reg extension and double click on it:

    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink]
    "MS PGothic MC"=-
    "Segoe Media Center"=-
    "Segoe Media Center Light"=-
    "Segoe Media Center Semibold"=-

    Works like a champ.
