  • Big problems with Win7 Preview of Monthly Rollup KB4041686

    Posted on October 18th, 2017 at 07:41 Comment on the AskWoody Lounge

    I just saw a heads-up from @abbodi86 about the Monthly Rollup Preview for Win7 that was released yesterday. It’s KB 4041686, the 2017-10 Preview of Monthly Rollup.

    As you know, I strongly recommend against installing Previews — they’re “previews” precisely because they aren’t ready for prime time.

    Here’s the problem.

    After installing KB 4041686, a SFC (System File Check) scan will report and fix an error in \system32\drivers\en-US\usbhub.sys.mui — even though there is no error.

    This is precisely the problem @abbodi86 reported to Microsoft after installing the old KB 3125574, which is the “convenience rollup” I call “Win7 SP 2.”

    The bug was fixed in  KB 3181988, but it’s back again.

    If you install KB 4041686, you’ll trigger a bogus SFC error even if you have KB 3125574 installed.

    Is anybody at Microsoft listening?
