Speedup Excel or Word if it is opening or closing slowly


  1. Click the Microsoft Office Button Button image, click Excel Options, and then click Add-Ins.
  2. In the Add-ins box, identify the add-in that you want to enable or disable and note the Add-in type located in the Type column.
  3. Select the Add-in type in the Manage box and then click Go.
  4. Select or clear the check box for the Add-in that you want enable or disable and then click OK.


  1. Click the Microsoft Office Button Button image, and then click Word Options.
  2. Click Trust Center, click Trust Center Settings, and then click Add-ins.
  3. Click the options that you want. These settings are not selected by default unless you work in an organization and your information technology (IT) administrator changed the defaults by using an administrator policy.
    • Require Application Add-ins to be signed by Trusted Publisher Select this option if you want the Trust Center to check for a digital signature on the dynamic-link library (.dll) file that contains the add-in. If the publisher has not been trusted, the Office program does not load the add-in, and the Message Bar displays a notification that the add-in has been disabled.
    • Disable notification for unsigned add-ins (code will remain disabled) This check box is available only if you select the Require Application Extensions to be signed by Trusted Publisher check box. In some situations, the dynamic-link library (.dll) file that contains the add-in might be unsigned. In these cases, add-ins signed by a trusted publisher are enabled, but unsigned add-ins are disabled silently.
    • Disable all Application Add-ins (may impair functionality) Select this check box if you don't trust any add-ins. All add-ins are disabled without any notification, and the other add-in check boxes are made unavailable.
