Removing Items
A lot of programs you install will add themselves to the right-click menu of your files and/or folders. And most times, you have no choice in the matter and, as a result, your right-click menu can get very long with added items you don't even use. The last person I was helping with this had a right context menu so long that the Rename option was no longer visible!
Fortunately, you can easily remove those unwanted menu items, if you know the registry values to edit. And it's not at all difficult once you know the keys responsible for the additions.
For Files, the secret lies in the "context menu handlers" under the shellex subkey for "All Files" which, in the registry, is nothing but an asterisk - like a dos wildcard, which means the values entered apply to all files. It is at the very top of the Root key, right here:
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
Click the the + sign next to the ContextMenuHandlers key, to expand it.
Now you will see some of the programs that have added items to your right-click menu. Simply delete the program keys you don't want.
Yup! It's that simple. If deleting makes you uneasy, just export the key before deleting it. Or, instead of deleting the values, disable them. Simply double click the default value for the program on the right hand pane and rename the clsid value by placing a period or dash in front of it.
ie; - {b5eedee0-c06e-11cf-8c56-444553540000}
Then exit the registry, refresh, and right click a file to see if the item was removed from the menu.
Some programs - like WinZip or WinRar - will add several items to your right click menu but all of them will be removed by deleting or disabling their one context menu handler.
Note that the above key only applies to the right click menu of files.
To remove entries from the right click context menu of folders, you need to navigate to the Folder and Drive keys:
HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers
All you have to do is follow the same procedure as for Files - either disable or delete items you wish to remove.
