Microsoft confirmed the existence of an update KB4556799 connectivity bug. When the company released the CU weeks ago, it meant to fix a couple of Windows 10 issues, including app security.
But as always, things did not go according to plan, and users started complaining about errors with the update. Some of the earliest complaints touched on issues like installation failure.
Microsoft’s looking into the KB4556799 connectivity bug
Some users are still reporting being unable to connect to the internet after installing KB4556799.
If you are experiencing this issue, you can breathe a sigh of relief. Microsoft is now aware of it, and is working to resolve it.
After installing this update on a Windows 10 device with a wireless wide area network (WWAN) LTE modem, reaching the internet might not be possible. However, the Network Connectivity Status Indicator (NCSI) in the notification area might still indicate that you are connected to the internet.
At the same time, the company confirmed having seen social media and news reports about multiple KB4556799 issues.
One Reddit user recently shared their awful experience with the update to the Windows Subreddit. The user reported performance issues, including browser crashes, after installing build CU KB4556799.
Another user got error 0x800f0988 after attempting to install the CU. When this bugshows on your screen, you just cannot install the update without fixing it first.
Still, other Windows 10 users have reported audio and graphics issues after installing the May 12, 2020 update.
It may be interesting to note that Microsoft’s official customer feedback channels are not receiving a lot of these complaints. Most likely, affected users are sharing their concerns through social media without directly engaging the Redmond-based corporation.
The company, though, said it is actively engaging customers who have raised any issue with the update.
