The size of the "HKEY_USERS\.DEFAULT" registry hive continuously increases on a Windows Server-based server

Symptoms

Assume that you have a server that is running Windows Server 2012 R2 or Windows Server 2008 R2 Service Pack 1 (SP1). Many users connect to the server by using a certain remote desktop application. In this situation, the size of the following registry hive may exceed the limit:
HKEY_USERS\.DEFAULT
Therefore, the users cannot connect to the server.

Cause

This issue occurs because of an error that occurs in the Print Spooler modules. When a user establishes a new remote desktop session to the server, the printer settings of the user are written in the following registry subkey:
HKEY_USERS\.DEFAULT\Printers\DevModes2
However, the printer settings are never deleted. Therefore, the size of the following registry hive becomes larger and larger, and various problems are caused by this behavior:
HKEY_USERS\.DEFAULT
