To uninstall Microsoft Lync 2010 Group Chat, use Programs and Features (on a computer running Windows 7 operating system operating systems) or Add or Remove Programs (on a computer running Windows Vista operating system operating systems).

After Lync 2010 Group Chat is uninstalled, several files remain on the computer. By default, these files are in the Application Data folder. For example, if you use the default location on a computer that is running Windows 7 Professional, the files are at the following location: C:\Documents and Settings\<NT username>\Application Data\ (where <NT username> is the user name used to sign into Group Chat).

The Application Data folder and the folders that it contains could be hidden.

The following items in the Application Data folder for Group Chat are not removed when Group Chat is uninstalled:

  • Accounts folder. Contains sign-in accounts and identifies the default account.

  • Logs folder. Contains Group Chat logs.

  • Preferences folder. Contains local copies of preferences.

  • Sounds folder. Contains sound files.

  • GroupChatConsoleLogger.xml file. Controls the logging level of Group Chat.

The location of these files meets the standards as set forth in “Designed for Windows XP Application Specification” at These are files that are meant to be retained in the original location when a user is deleted or moved.
