Are you familiar with the KB4555452 update? You might have seen is as Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version Next for x64.

What is KB4555452?

Last time we updated it was just after the Windows 10 build 19645.

KB4555452 installs after every build

As the description suggests, KB4555452 is an update for .NET Framework 3.5 and 4.8 for Windows 10 that installs as a file cabinet folder inside SoftwareDistributionDownload.

The problem is that, as the Windows insider Johnny_55 states on the Microsoft Answers page, the file keeps disappearing after every build update.

The insider suggests that after the update, Windows Update checks for KB4555452 and doesn’t find it, so it needs to download and install it again.

Why is KB4555452 disappearing every time?

There are two plausible explanations until now:

  1. KB4555452 is not included in the new builds by mistake, and thus it needs to reinstall.
  2. KB4555452 is not there on purpose so that Microsoft can update it every time for security purposes.

As you might have guessed, we don’t have an explanation from Microsoft about this strange KB4555452 and its magical disappearance.

Make sure we will follow the lead further and let you know when we have an answer.
