Issue: How to fix Microsoft Store error 0x803F800A in Windows?
Hello. Whenever I try to download an application from Microsoft Store, it says there was an error, and I can't download it. The error code mentioned is 0x803F800A. I am running Windows 10 version 21H2, if that helps.
Solved Answer
Microsoft Store, previously known as Windows Store, is a digital marketplace that hosts thousands of apps in its arsenal, allowing users to access it at any time. Users can access the Store directly from their computer without having to visit any third-party websites, which makes it extremely convenient and secure, as all the applications undergo excessive security checks before being put in there.
Overall, security experts recommend always picking official sources rather than third-party ones, as the latter might push potentially unwanted or even malicious programs via bundlers.
Despite being one of the most useful assets since the Windows 8 release, Microsoft Store has flaws as well. One of the most common complaints is that it sometimes fails to work, and users are faced with errors such as 0x803F800A – an issue that many users have been reporting for several years now.
People might encounter Windows errors under different circumstances. As evident, the Microsoft Store errors occur when users try to download a new app or update an existing one. The 0x803F800A error was seen on all operating system versions, including the latest Windows 11.
The error message users receive is rather generic, and there's not much information provided about why the issue occurred or how to resolve it. This is not surprising, as Microsoft can't provide immediate fixes due to multiple factors that could influence the error's occurrence, and it varies from machine to machine.
In most cases, the errors in Microsoft Store occur due to a simple bug[1] that should go away in a short amount of time. If it doesn't, there are several methods to initiate the change and return back to normal operation.
