SYMPTOMS

Consider the following scenario:
  • You have an application on a computer that is running Windows 7 or Windows Server 2008 R2.
  • The application calls the RegLoadKey function to load a registry hive file.
  • The application calls the RegUnLoadKey function to unload the registry hive file without making any changes.
In this scenario, the Accessed time file attribute and the Modified time file attribute of the registry hive file are updated. However, the expected behavior is that only the Accessed time file attribute is updated.

This scenario may cause an issue in the following environments.

Environment 1

  • You configure the Delete user profiles older than a specified number of days on system restart Group Policy to remove the user profiles that are not accessed for some time.

    Note To find the Delete user profiles older than a specified number of days on system restart Group Policy, do the following. Under Computer Configuration, expand Administrative Templates, expand System, and then click User Profiles.
  • You install and configure some antivirus applications or some anti-malware applications to run on the servers. These applications regularly scan user profiles for security.
In this environment, every time that the antivirus applications or the anti-malware applications scan the user profile registry hive files, the files are updated. Therefore, the configured Delete user profiles older than a specified number of days on system restart Group Policy becomes ineffective.

Environment 2

  • You configure the TS connection broker together with the profile server to use a roaming profile.
  • You set up some antivirus applications or some anti-malware applications to run on TS. These applications regularly scan user profiles for security.
  • When a user logs off from the TS, the latest user profile is uploaded to the profile server.
  • On each TS, user profiles are scanned by antivirus applications or anti-malware applications. Therefore, the modified time on the user profiles on each TS has a newer time stamp than that of the user profiles on the profile server.
  • When the user logs on to the TS, the user profile on the local TS is loaded because the modified time of the user profile is newer than that of the user profile on profile server.
In this environment, the user profile on TS that has older contents is loaded because its modified time is newer than that of the user profile on the profile server. Therefore, the user loses various settings such as the last setting on the desktop, the Outlook profile, and application settings.
