Fix PowerPoint Startup Hangs

If you are having problems with PowerPoint starting very slow or freezing upon startup where you have to perform a warm boot (CTRL+ALT+DEL) just to recover? You may be having a problem with one certain file. PowerPoint stores any toolbar, button, or menu customizations in a special PCB file. Unfortunately, it seems to record customizations by adding to this file, not by replacing the old configuration with the new one, so the PCB file grows with every change. Most add-ins create a new toolbar at startup, then delete it at shutdown, so every time you start or quit PowerPoint, the PCB file grows larger. The more add-ins you have loaded, and the more toolbars they create, and the more often you start and quit PowerPoint, the faster the PCB file grows. Sooner or later, it reaches a size where PowerPoint is no longer able to cope with it. The next time you start PowerPoint and an add-in tries to create its toolbars, PowerPoint freezes up. Totally. So, then what do you do about? Follow these procedures:

This PCB file may take considerable time in the making, but once in awhile it just may be worth your benefit to delete this file and make PowerPoint load quicker.
