Nothing to worry about though, but you should all check if the update installed correctly on Windows 10

The experience with the Windows 10 cumulative updates released this month has so far been close to flawless, but as it turns out, a minor bug is still hitting a small number of computers.

The Windows 10 April 2018 Update cumulative update, KB4457128, sometimes appears to install without requiring a reboot.

This is without a doubt unexpected, especially because KB4457128 is listed as successfully installed. However, it’s important to know that this is just a bug, and the cumulative update must prompt for a system restart.

Users whose computers experienced this behavior, with KB4457128 not asking for a reboot and being listed as installed correctly, must manually restart their systems and then check for updates once again.

KB4457128 should show up in Windows Update, with the download and install process this time running correctly without any further issues.

How to tell if the update installed correctly

While it’s not yet clear why this happens, there are several users on reddit confirming that KB4457128 isn’t asking for a system reboot. Microsoft hasn’t provided any information on this bug just yet.

The recommended thing to do after KB4457128 shows up as successfully installed is to check the OS build number on your system, as this cumulative update should bump it to version 17134.285.

To do this, you can click the Start menu or press the Windows key + R and type winver. In the new dialog, the version number should be the one mentioned above, and anything below it means your computer hasn’t correctly installed cumulative update KB4457128.

Other than that, it looks like all cumulative updates install correctly this month without any reported issues, and this is quite an achievement given how many problems were encountered in the past on Patch Tuesday.
