Block all unmanaged add-insDisable installed OneNote Add-ins

The first option will help you block all the additional add-ins only if you use the List of managed add-ins setting. However, if you want to disable all add-ins irrespective of the filter, you need to use the second setting.

Either way, double-click on the respective setting, choose the Enabled option. Then, click the OK button to save the change. However, if you want to revert all changes, you need to open those two settings one after one, select the Not Configured option, and click the OK button to save the change. For your information, if you enable the second setting, Disable installed OneNote Add-ins, it overwrites the former setting.

To disable all unmanaged and installed OneNote add-ins using Registry, follow these steps: Let’s check out these steps in detail. First, you need to open the Registry Editor on your computer. For that, press Win+R > type regedit > click the OK button. If the UAC prompt appears, click on the Yes button.

Then, repeat the same steps to create all the sub-keys one after one. Once the onenote key is created, you need to create two sub-keys here. For that, right-click on onenote > New > Key and name it resiliency.

Then, right-click on resiliency > New > DWORD (32-bit) Value and name it as restricttolist.

Double-click on it to set the Value data as 1 and click the OK button.

After that, you need to create the second sub-key by following the same steps as mentioned above and name it as security. Following that, right-click on security > New > DWORD (32-bit) Value and set the name as disablealladdins. Double-click on it to set the Value data as 1 and click the OK button.

Once you are done with all those steps, close all windows and restart your computer to get the change. Like the GPEDIT method, you can revert all changes. For that, you can remove those two REG_DOWRD values. To do that, right-click on each of them, select the Delete option and click the Yes button. Read: How to use the Notebook Recycle Bin in OneNote
