KB4549951 Update for Windows 10: Bluetooth and Wi-Fi Issues

04/26/2020 Windows 10 update

The next update to Windows 10 caused problems with the system and network connections. However, problems are observed on a relatively small number of systems.

Updated: 04.25.2020. Microsoft reported on the official portal Known Issues and Notifications that it saw messages on social networks about updating KB4549951 for Windows 10, versions 1909 and 1903, which mention Bluetooth problems, system crashes with a blue screen and other related problems.

As the company notes, to date, developers have not seen that these problems are reflected in telemetry, support data or customer feedback channels. If you have any problems, report it through the Feedback Center application, which is launched using the Windows + F keyboard shortcut.

Some users have encountered a failure to install update KB4549951 for Windows 10, versions 1909 and 1903, while other users complain about problems with Bluetooth and Wi-Fi connections after installing the update. Also, individual users report a noticeable decline in system performance and the emergence of a blue screen of death (BSOD).

The KB4549951 update has seriously slowed down network connection performance on Windows 10 Pro v1909 workstations. It took several minutes to download the Outlook 365 service hosted on the Exchange server and the remote desktop with the black screen of the target computer. The update also causes VMware to freeze. After the update was removed and the update installation delay was configured, everything was restored in normal mode.

On the Microsoft forum and on third-party resources, there are a lot of reports about update installation failures, about Bluetooth and Wi-Fi malfunctions and about the appearance of BSOD.

At the time of publication, Microsoft did not recognize any upgrade issues. It is important to note that Windows 10 runs on more than 1 billion systems, so often errors occur on a small number of devices.
