The most reasons for viewing disable post is maybe to re-enable an add-in. An add-in is an additional functionality that is added to a program on your PC (and can be called an extension). It may be downloaded or written by a PC owner if he/she is a programmer. This post is vital since many people are finding it difficult to view list of disabled items because they don't know where the location of Add-in is on their PC. To find your add-in lists, there is a tiny arrow pointing down at the top page of the program you opened. This tiny arrow is called Customize Quick Access Toolbar, when you click it, you will see More Commands, click it and you will see Add-in To view the list of disabled items, display the Disabled Items dialog box by doing the following; take for instance, the Microsoft Office program.

If it's in Word, Excel, PowerPoint, or Access: Click the Microsoft Office Button ==> click Program Name Options e.g PowerPoint ==> Click Add-Ins. On the Manage menu, click Disabled Items ==> click Go. If it is in Visio, Outlook, Publisher, or InfoPath: On the Tools menu, click Trust Center ==> click Add-ins. On the Manage menu, click Disabled Items ==> click Go. If it is in OneNote, Project, or SharePoint Designer: on the Help menu, click About Microsoft Office Program Name e.g OneNote ==> Click Disabled Items. After you view the items listed in the Disabled Items dialog box, you can select an item and then click Enable to turn it on again.
Enabling some items may require you to reload or reinstall an add-in program or reopen a file. After you enable an item, the program may run into a problem the next time it starts. In this case, you are prompted to disable the item again.
