Occasionally the SolidWorks profile of a particular user can get corrupted – resulting in painfully slow loading times for Assembly Drawings (particularly across a network).
To reset the profile for the current user within Windows XP:
 Click Start => Run and type in “regedit.”
 Expand “HKEY_CURRENT_USER\Software\SolidWorks”. Right-click on it and then rename to “solidworkscorrupt”.
 Close the registry editor and re-start SolidWorks. All the settings should have reverted to their “factory default”.
