How to fix Windows error 0x80040154 when opening apps?

Issue: Hello, can somebody help me to fix error code 0x80040154? Every time I try to use Windows apps, such as Mail, Photos, and others, they won't open, and instead, I receive the error. Any suggestions would be appreciated.

Solved Answer

Windows uses a system where it assigns particular error codes (usually, they follow a certain pattern) when certain issues occur. This allows users to easier troubleshoot problems they might sometimes have on their operating system. In this case, we are talking about error 0x80040154 when trying to open apps in Windows 10, 11, or other versions.

In most cases, users run into the error when they are trying to launch certain Windows apps on their computers, including Mail, Outlook, Calendar, Cortana, MS Edge browser, and more. In some cases, people can't even launch and use Microsoft Store as well. There are also people who said that the 0x80040154 error occurs exclusively when they are trying to download and install the recent system update.[1]

Here's the message of the error which shows up when users are unable to open apps:

As evident, the message does not convey any significant details about the problem, and neither does it explain how to fix it. However, Windows rarely provides any solutions to their errors, simply because too many variables can differ from computer to computer.
