Windows 10 KB4346877 Starts Rolling Out Carrying a Small Bug Fix-February 2024

Microsoft will stop supporting Windows 10 Anniversary Update later this year. However, until then it will continue to deliver regular security updates to all the systems that haven't been upgraded to the latest OS versions. Do note that version 1607 has already reached theend of service for Windows 10 Home and Pro editions; updates are only being delivered to Enterprise and Windows 10 Education editions.

The Redmond software maker has released a plethora of security patches to different versions of Windows 10 in July. The company has today started to deliver its fourth cumulative update for Windows 10 Anniversary Update version 1607 for the month of July.The update bumps up the build number to14393.2396 and carries a small changelog fixing an issue introduced by an earlier July update.

Here's what is being fixed with Windows 10 version 1607 (KB4346877)

This update addresses an issue that was introduced in the July 2018 .NET Framework update. Applications that relyon COM components were failing to load or run correctly because of “access denied,” “class not registered,” or “internal failure occurred for unknown reasons” errors.

For more information about this issue, see the following article in the Microsoft Knowledge Base:

4345913 "Access Denied" errors and applications with COM activation fail after installing July 2018 Security and Quality Rollup updates for .NET Framework

Windows should update your systems automatically to this latest update. Alternatively, you can manually download the update from the official cataloghere.

Keeping up with Windows updates has become a nuisance with a number of cumulative updates arriving each month and not always bug-free. Microsoft is, however, reportedly working on offering a device as a service or a desktop as a service paid plan to businesses where it will take care of the process of keeping your Windows 10 devices up to date and secure. The company is also looking into stopping Windows 10 machines from rebooting when a user is inactive for a little while. More details available in our previous coverage.
