Though there's no official word from Google yet, it looks like the Chrome launcher has come out of developer preview mode and into full release, at least for Windows. On our own PCs, the installation placed the launcher app on the start page, taskbar and desktop for Windows 8 and in Windows 7's menu bar. From there, you can quickly access Chrome, the Chrome store, Gmail and any other apps that work with Google's ubiquitous browser / OS. We're not sure when it'll hit OS X or Linux (Chrome OS users have had it for awhile), but if your Windows workflow revolves around Mountain View's myriad products, you can enable it at the source.
