Set Google as IE 11 default search provider

Create a new GPO and navigate to User Configuration->Preferences->Windows Settings-> Registry.

Generate a GUID for the registry key you are about to create

Create the "DefaultScope" Registry Key with the GUID as the value data.

Copy this key and then add the GUID and remove the Value name

Copy and paste this key now 5 times so you should have the following 6 keys

Update each key with the following Value names and Value Data:-

Value Name	Type	Value Data
DisplayName		Google
FaviconURL		https//:google.com/favicon
OSDFileURL		https://microsoft.com/en-us/IEGallery/Google
ShowSearchSuggestions	REG_DWORD	00000001
SuggestionsURL		http://clients5.google.com/complete/search?q={searchTerms}&client=ie8&mw={ie:maxWidth}&sh={ie:sectionHeight}&rh={ie:rowHeight}&inputencoding={inputEncoding}&outputencoding={outputEncoding}
URL		http://www.google.com/search?q={searchTerms}&sourceid=ie7&rls=com.microsoft:{language}:{referrer:source}&ie={inputEncoding?}&oe={outputEncoding?}

Entries will look as follows:-

All that is left to do now is restrict the search provider to the DefaultScope (Google) entry that you just created.

Now fire up a machine to test it works.
