If you wanted to enjoy hands-free Google searching from your desktop, your only option was to install an extension or become an early tester. The downside was that you'd have to accept some additional bugs might come your way. No more -- Google has rolled out a Chrome update that integrates the company's now iconic "OK Google" command directly into the latest version of its browser and in Chrome OS. As long as you're based in the US or have Chrome set to US English, any time you visit the Google homepage or open a new tab, you can quickly say (or loudly shout, the choice is yours) "OK Google" to perform a search, ask a question or schedule a reminder. As long as you fulfil the geographic requirements (or are happy to tinker with Chrome's language settings), you should be able to test those voice commands seconds after you update.
