Microsoft has confirmed it’s investigating a new bug in a Windows 10 cumulative update, but this time it’s not one of the very most recent releases, but an update that was originally published in February.
The Redmond-based software giant explains that cumulative update KB4535996 could cause Web connection error on Windows 10 devices where it’s installed, so it’s now looking into reports trying to figure out what happens.
“After installing KB4535996 on a Windows 10 device with a wireless wide area network (WWAN) LTE modems, you may be not able to get to the internet although the Network Connectivity Status Indicator (NCSI) in the notification area shows as attached to the internet,” the company says.
This cumulative update is aimed at Windows 10 version 1903 and Windows 10 version 1909, because the two share a substantial area of the code and for that reason get the same updates. Both of them are affected by the problem, and Microsoft says a similar Internet connection error could also be experienced on Windows Server version 1903 and Windows Server version 1909.
Another bug within the same cumulative update
At this point, there’s very little you can do, but Microsoft claims it’s already working on an answer and this you might be shipped in mid-July. In other words, you really shouldn’t hold your breath for that fix, as it could go live in some 8 weeks as part of the July 2020 Patch Tuesday cycle.
Exactly the same cumulative update also comes with another issue that Microsoft has acknowledged and which in turn causes Windows 10 Pro Education to actually get a genuine edition of Windows 10 Education when activating a license.
“Windows 10 editions for education customers, Windows 10 Pro Education develops the commercial version of Windows 10 Pro, and Windows 10 Education builds on Windows 10 Enterprise. This bug isn’t likely to introduce any negative experiences for purchasers,” Microsoft says.
A treatment for this bug is also on its way, Microsoft confirms.
