While Microsoft has promised to make big changes to Windows 10, problems with the operating system continue to mount up.

The problem, once again, is KB4556799, a recent Windows 10 update pushed to millions of PCs which has already caused numerous issues, including Blue Screen of Death (BSOD) crashes, deleted user data, performance issues, broken audio and more.

Microsoft is investigating these problems, but the company has now also confirmed on the official KB4556799 update page that it can break Internet connections as well. .

Microsoft warns that the update impacts Windows 10 computers with 4G LTE modems and after installing it “reaching the internet might not be possible.” Compounding this problem, Microsoft states that affected users are unlikely to be able to identify the cause because “the Network Connectivity Status Indicator (NCSI) in the notification area might still indicate that you are connected to the internet.”.

The update has already been described as “wrecking PCs” and, in addition to all the problems listed above, you can also add in reports of impacted gaming performance (déjà vu) and broken web browsing (ditto). .

Unfortunately, this has not worked for all users because the update can also break settings menus.

But, if this does work, then I would also strongly suggest you install the Windows Update troubleshooter and proactively block KB4556799 to stop it from coming back. 

To Microsoft’s credit, it has recently put out a lot of fires and promised to refocus it’s next-gen Windows 10X operating system for laptops and PCs, But, for many users who are (understandably) sick of Windows 10’s ongoing problems, I suspect enough is enough.
