The logon process hangs at the "Welcome" screen or the "Please wait for the User Profile Service" error message window

Introduction
This article describes an issue that occurs when you log on to Windows 10, Windows 8.1, Windows RT 8.1, Windows Server 2012 R2, or Windows Server 2012. An update is available to fix this issue. Before you install this update, see the Prerequisites section.
Symptoms
When a user logs on to a computer, either directly on a client computer or through a remote desktop connection, the logon process may hang at the "Welcome" screen or the "Please wait for the User Profile Service" error message window.

When this issue occurs, the user's current password does not match the password that is cached in Credential Manager. This issue can occur immediately after the user or an administrator performs a password change. It can also occur after some time has passed after the password change.

The following configurations are known to contribute to this issue:

  • The user has a mapped home folder to a Distributed File System (DFS) path, such as \\contoso.com\homefolders\user.
  • The user has enabled the "Set a default associations configuration file" Group Policy Object for file association sets. Also, the XML is stored in a DFS path, such as \\contoso.com\netlogon.
  • The user has GPP for Drive Maps that map a folder in a DFS path, such as \\contoso.com\data1.

Cause

This issue occurs because of a deadlock between Credential Manager and the Redirector (RDR) and Data Protection API (DPAPI).
