| Message: | Windows cannot unload your classes registry file – it is still in use by other applications or services. The file will be unloaded when it is no longer in use. |
| Explanation | |
|
Windows unloads each user’s profile and user’s section of the registry when the user logs off. This message indicates that Windows could not unload the user’s profile because a program was referencing the user’s section of the registry. This locked the profile. The registry cannot unload profiles that are locked and in use. When the program that is locking the profile is no longer referencing the registry, the profile will be unloaded. |
