Add-in Management

View, inspect, and understand the status of your Microsoft Office add-ins

Add-in inventory

The Add-ins page lists every COM and VSTO add-in Deck discovered across Excel, Outlook, Word, and PowerPoint. For each add-in you can see:

• Name and publisher
• Type - COM, VSTO, or VBA
• Status - Enabled, Disabled, or Admin-managed
• Office app - Excel, Outlook, Word, or PowerPoint
• Load behavior and the registry path it came from

Add-in detail

Click any add-in to open its detail view, which shows:

• The ProgID (the add-in's registry key name) and full registry path
• The current LoadBehavior value
• Performance metrics over time - see Metrics
• Any crashes attributed to it - see Crash Analysis

The ProgID shown here is what administrators use when defining managed profiles.

Filtering and search

Use the search bar to find add-ins by name, and the filters to narrow the list by Office application or status.

Enabled vs. disabled

Whether an add-in is enabled is controlled by its LoadBehavior value, which you change by activating a profile - not by editing add-ins one at a time. This keeps your configuration reproducible.

Admin-managed (HKLM) add-ins

Add-ins installed machine-wide (under the HKLM registry hive) are deployed by your IT administrator. Deck shows them with a lock icon and does not modify them - profile activation only ever changes your own user-hive (HKCU) add-ins. If you need a machine-wide add-in enabled or disabled, contact your IT team. For the underlying registry detail, see Registry Details.

When add-ins are missing

If Deck shows fewer add-ins than you expect, or a specific one is absent, see Add-ins not detected.
