Removing Customizations from PCB Files in PowerPoint 2010 for Windows

PowerPoint add-ins help in adding new capabilities that can polish your presentation in many ways. But when the time comes to uninstall these add-ins for whatsoever reason, you might be surprised to find their menu customizations still exist! Click those menu extensions and nothing may happen, but these menu options are still there!

In another scenario, you may have customized your PowerPoint menus and toolbars to a large extent, and may now want to restore everything to a pristine state, almost like how the interface looked when you first installed PowerPoint.

In either case, it is possible to lose all these customizations. The key to this solution lies in PCB files. So what's a PCB file? Let's learn more.

A PCB file is a PowerPoint Settings file where PowerPoint stores every customization you make within the program interface. This includes moving toolbars, the appearance of new add-in menus and toolbars, customizing presentations, etc.

Whenever PowerPoint launches, it looks for this PCB file within a typical location:

C:\Users\<UserName>\AppData\Roaming\Microsoft\PowerPoint

If no PCB file is found, PowerPoint creates a new one! In other words, PowerPoint restores all default. Therefore, this creation of a new PCB file can be put to advantage. So to counter this issue, we need to rename or delete the errant PCB file:

1. Make sure PowerPoint 2010 is closed. Then navigate to the path mentioned below:
2. For Windows 7 and higher:
3. C:\Users\<UserName>\AppData\Roaming\Microsoft\PowerPoint
4. For Windows XP:
5. C:\Documents and Settings\<UserName>\Application Data\Microsoft\PowerPoint
6. Substitute <UserName> with the user name set for your computer.
2. Within this folder, you will find a PCB file, as shown in Figure 1 below. You may see more than one PCB file here if you have multiple versions of Microsoft Office installed on your system. Refer to Figure 1 again and you will see that we have another file called PPT15.pcb. If you also have this file, please leave that untouched since that pertains to PowerPoint 2013, a later version. The file you need for PowerPoint 2010 will be named PPT14.pcb or similar.

PowerPoint Versions and PCB File Names

The file names of the PCBs indicate which version of PowerPoint they influence:

PPT16.pcb relates to PowerPoint 2016
PPT15.pcb relates to PowerPoint 2013
PPT14.pcb relates to PowerPoint 2010

Don’t see the PCB file extension? Your file extensions need to be made visible. To learn more, look at our Show File Extensions tutorials.

3. Now you can either delete the PCB file or you can rename it with a .bak or another extension. We highly recommend that you rename rather than delete the file! For this example we will rename the file with a .bak extension, as shown in Figure 2 below. You can delete the PCB file after a new PCB is created, and everything seems to be working well

Safely Working with PCB Files

Always keep a backup copy of your PCB file. This backup file may come handy when you want to roll back PowerPoint's customizations to an earlier stage.

Also, never rename or delete a PCB file while PowerPoint is still open.
4. Now launch PowerPoint 2010. It might take a while to load since a new PCB file is being created. At this point of time, get back to the original folder that contained the PCB file. You'll notice that a new PCB file has been created.
