on Windows

Need help! Xbox live on Windows10 stopped working. Error code 0x80070520. A few days ago I reinstalled Windows from scratch due to multiple problems on the system. Each time I try to log in using Microsoft Store or Xbox App, I get an error, which explains nothing. How can I fix it?

Windows 10 users receive Error Code 0x80070520 when trying to sign in to Windows Store[ref en-1] or run some of the Windows Store apps, including Xbox, Microsoft Solitaire Collection and Microsoft Ultimate Word Games, and others.

Based on the users' reports, the problem typically starts right or soon after installation of Windows 10 patches,[ref en-2] cumulative update or fresh install. As explained by experts, the issue may be triggered by corrupted Windows update components, which might have a negative effect on the update process, Windows apps, and Windows Store service.

The same error was registered soon after Windows 10 release back in 2015. At this time, the core problem of the bug turned to be corrupted Windows Update components, which is why people received: 

There were some problems installing updates, but we'll try again later

In fact, Windows Update[ref en-3] and Windows Store services are closely related, and, therefore, if one fails to work, the other may either start malfunctioning or stop working in tandem.

You can find the tutorial on how to do that in this post.
