For the people so much annoyed with Google forcing them to go to their local domain version, e.g. Google.com.kw or what ever your region is, this is how to switch back to normal Google.com as your default search. Simply go to your local Google home page, e.g. Google.com.kw, and then click on Google.com in English.
NOTE: At time of Google.com.kw launch, this same solution did not use to work as it should. It would take you back then to Google.com, but if you use the browser default Google search engine you would land again on .KW domain. Next day, it was working properly. So I’m not sure if this same link works the same way on domains other than .KW. Let me know how it goes with you.
UPDATE: Bad news. Google.com.kw is enforced on me back again and I assume many others when searching using Chrome Address Bar. Same trick does not work. Firefox Google Search Engine and address bar both dont have the same problem. Looks like we’re gonna need a hack for it ;/. Thank you Google for not doing evil. Thank you.
UPDATE 2: I have tried to contact Google Chrome feedback for reporting this behavior. Not the best place, but it is a place that they will read at least.
UPDATE 3: I found the solution for Chrome Google Default Search. You can read it here.
