SYMPTOMS
After you log on, Explorer.exe may repeatedly generate access violation error messages. The access violation occurs in the Browseui.dll module. However, this symptom does not occur when you log on with administrator rights.



CAUSE
This problem may occur if one or more registry keys are inaccessible. The inability to obtain access to registry keys would run an errant code path that would always cause a fault. The fault occurs because the incorrect release method was being called on the object.
