  • Win10 version 1809 buglog – including troubling tales of lost user data

    Posted on October 4th, 2018 at 08:05 woody Comment on the AskWoody Lounge

    I’m keeping a log of bugs that are uncovered in the just-released Win10 version 1809. Not that I recommend you install it, mind you — quite the opposite. But I figure the world could use a one-stop bug shop, to stay on top of things.

    So far, we have one officially recognized bug:

    Intel Audio displays an intcdaud.sys notification. Microsoft and Intel have identified a compatibility issue with a range of Intel Display Audio device drivers that may result in excessive processor demand and reduced battery life. As a result, the update process to Windows 10, version 1809 fails (KB4465877).

    Customers who see this notification when setting up their Windows 10 October 2018 Update have an Intel Audio Display device driver (intcdaud.sys, versions 10.25.0.3 – 10.25.0.8) installed on their systems.

    On the “What needs your attention notification”, select the backbutton to remain on your current version of Windows 10.

    And a bunch of unacknowledged problems, with the most distressing involving deleted user data:

    • I’m seeing reports all over about user data getting deleted during the upgrade. Still don’t see a unifying cause. (Brad Sams has an independent report on Petri.com.)
    • Various user folders (in this case C:\Users\Public\Documents and C:\Users\<user>\Documents) disappear.
    • Entire user profiles disappear. In this case, the problem may be with the Group Policy setting “Delete user profiles older than a specified number of days on system restart.” But this thread says that’s bunk, because the problem occurs on Home machines.
    • Deleted almost all the data on a solid state drive. It’s possible that the data was shuffled off to OneDrive, and is sitting there awaiting a full sync.
    • There’s the always-reliable problem set with the installer trying to bring in bad drivers.
    • The installer uninstalls CCleaner — which may be a bug or a feature, your choice.
    • If you disable IPv6,  the Edge and Microsoft apps won’t connect to the Internet.
    • Some issues with dark mode file explorer.

    The known problems with Task Manager are supposedly solved in the next-next version of Win10, RS6 version 19H1, which moved to build 18252 yesterday:

    • We fixed the issue causing Task Manager to report inaccurate CPU usage.
    • We fixed the issue where the arrows to expand “Background processes” in Task Manager blink constantly and weirdly.

    Of course, that doesn’t fix the bug in Win10 version 1809, but it’s likely that we’ll see a fix in the first cumulative update (which I expect next Tuesday).

    There are the usual problems with PCs that don’t upgrade properly — an HP notebook, for example, that hangs during the upgrade process and another report blaming UX Patcher.

    Have you hit a bug? If so, please reply to this post and include links whenever possible.
