Restoring Commands Not Available from the Customize Dialog Box
Some commands, especially those found in hierarchical menus, cannot be restored from the Customize dialog box. To restore these commands, you must import a new collection of IDE settings.
To import new IDE settings
On the Tools menu, click Import and Export Settings.
On the Welcome to the Import and Export Settings Wizard page, click Import selected environment settings, and then click Next.
On the Save Current Settings page, decide whether or not to save your existing settings, and then click Next.
On the Choose a collection of settings to import page, under the Default Settings folder, choose a collection of development settings that has the commands you want to use. If you do not know which collection to choose, try General Development Settings or Visual C++ Development Settings, which provide the most debugger commands.
Click Next.
On the Choose settings to import page, under Options, make sure Debugging is selected. Clear the other check boxes, unless you want to import those settings as well.
Click Finish.
On the Import Complete page, review any errors associated with resetting your settings under Details.
Click Close.
