How to fix KB5017859 fails to install on Windows 11?

Issue: Hi, I keep getting this notification on Windows that I miss some important updates. I tried installing KB5017859 several times, and it just gets stuck in the middle and says it is unable to install it. Please help me with this, thanks.

Solved Answer

Updates are downloaded and installed automatically as soon as the system is started, at least if the update settings were not tampered with. Microsoft usually delivers them on Patch Tuesday,[1] which is the second Tuesday of every month. KB5017859 is another typical update that should have arrived in millions of Windows 11 users' systems, but it didn't happen that way.

Many users were unable to install the KB5017859 patch successfully. This problem is not unique to this particular update but is more prominent for installation failures with this release. Users may experience various error codes when dealing with update failures, such as 0x8024A003 or 0x80004002.

The update was released on September 20, 2022, to the public. It is an Update Preview for cumulative dependability improvements to the .NET Framework 3.5, 4.8, and 4.8.1 for Windows 11.[2] While the update is nothing out of the ordinary, users are recommended to apply the latest version as soon as possible for more stability and better performance.

KB5017859 fails to install issue might not sound significant, but update failures should be taken seriously, as there could be underlying issues occurring with the system. For example, incorrectly installed updates may prevent newer versions from being installed in the future. Likewise, malware[3] could be causing the problem, hence we recommend scanning the system with security software as a precautionary measure.
