How to fix Microsoft Store error 0x803FB005?

Issue: Hello, I can't install any apps from Microsoft Store due to the 0x803FB005 error. The message said to wait a bit – so I did, but I still got the same problem several days later. I am using Windows 10 version 22H2 if that helps.

Solved Answer

Microsoft Store error 0x803FB005 is a common issue that Windows users may encounter when trying to download certain apps, especially games. In some cases, this error can also prevent users from updating and downloading apps altogether. Reports suggest that this problem is not exclusive to a certain Windows version and has been around for several years, with no universal fix for it.

Several factors can cause error 0x803FB005. For instance, a glitched Windows Store can malfunction and lead to this error code. If this is the case, resetting the Windows Store either from the terminal or the GUI should resolve the problem. Additionally, file corruption can also cause this issue, and a set of special commands via an elevated Command Prompt should be able to take care of the issue.

Another possible cause of the 0x803FB005 error is an overprotective third-party antivirus suite. Some affected users have reported that disabling real-time protection before initiating the app download or uninstalling the security app altogether has helped resolve the issue. It's worth noting that Microsoft released a patch addressing the error at the beginning of 2019. So, installing every pending update and bringing your OS version up to date can automatically resolve it to some.
