Whenever I right-click on my Windows desktop to open the context menu, I have two identical entries in it.

How can I remove the extra entries?

Find in your registry following key-
HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers
you will see a key named "igfxcui" in your case you will find these keys 2 times (or may be similar named, cause it seems that one is older and one is newer version!
export those two keys(in case of you lost it)
First delete one of those keys,and check your context menu,is satisfied,then good,if not then restore the exported keys and delete the other one!
or you may use these tools -

(In Autoruns,Go to explorer tab to enable or disable context menu items)
Here is the answer of Ramhound:
Remove the entry manually and/or uninstall the software that added them in the first place. This indicates you have two separate versions of your display driver installed. Likely cause by the fact you didn't uninstall it before you try installing a previous version.
