Oops, something went wrong! In an ideal world, installing a new piece of software or grabbing the latest update would be a simple matter of accepting any necessary terms and conditions and then sitting back and watching the update successfully install.

However, where Microsoft’s latest April 2018 Update is concerned, that’s not the case for a lot of people with error 0x8007042b causing a lot of concern for a lot of people.

Once upon a time, before software shipped with the complexity that we now have with OSes like Windows 10 and macOS, a company would generally provide a device owner with information about what has actually gone wrong.

These days, that simply doesn’t happen as often as it should, meaning that Microsoft is simply saying “Something went wrong” and providing the 0x8007042b error code via a user-facing dialogue box. Some of Microsoft’s more advanced users may know exactly how to troubleshoot those issues but the average PC or tablet owner would have no idea.

This particular error is caused due to an attempted upgrade using the Update Assistant. Some of those installations are working without issue, and others are failing and throwing up this seemingly random error code. If you have been consistently receiving this error code when trying to update via Update Assistant, then it’s time to try a different method.

Thankfully, you aren’t going to be left alone to figure this out for yourself, meaning that we have an array of options for you below which will allow you to get this latest update installed without having to suffer from this error. Pick your preferred route from below:

  1. Using the Windows Update flow: Download & Install Windows 10 April 2018 Update 1803 Via Windows Update, Here’s How
