Symptoms

When a local user logs onto a Windows 8.1 or Windows Server 2012 R2-based computer, a Microsoft-Windows-AppReadiness event ID 215 error is received.

For example, the following event log is received if the computer is running Windows Server 2012 R2:

Log Name: Microsoft-Windows-AppReadiness/Admin
Source: Microsoft-Windows-AppReadiness
Date: date
Event ID: 215
Task Category: (1)
Level: Error
Keywords: (2)
User: SYSTEM
Computer: computer
Description: 'ART:ResolveStoreCategories' failed for Administrator. Error: 'Class not registered' (0.015623 second)

The following event log is received if the computer is running Windows 8.1:

Log Name: Microsoft-Windows-AppReadiness/Admin
Source: Microsoft-Windows-AppReadiness
Date: date
Event ID: 215
Task Category: (1)
Level: Error
Keywords: (2)
User: SYSTEM
Computer: computer
Description: 'ART:ResolveStoreCategories' failed for Local_Users. Error: 'The network location cannot be reached. For information about network troubleshooting, see Windows Help.' (0.2968801 second)

Cause

The issue occurs because the AppReadiness service queries the Microsoft Store for the category names that are associated with the Microsoft Store Apps installed on the computer when a user logs on for the first time.

The AppReadiness service generates the event logs if the task that obtains the category names fails. A local user account does not have an associated Microsoft account to be used to connect to the Microsoft Store to retrieve the requested data. Therefore, when a local user logs on, the issue that is described in the Symptoms section occurs.

Resolution

This error can be safely ignored.
