Today, we’re announcing that on January 1, 2017 we will discontinue support for the Google Drive desktop app on Windows XP, Vista and Server 2003 since these platforms are no longer actively supported by Microsoft. The Google Drive desktop app (officially: “Google Drive for Mac/PC“) will continue to function on these platforms, but will not be actively tested and maintained. If you are still on one of these unsupported platforms, we encourage you to move to a newer version of Windows to continue using Google Drive desktop app.
Launching to both Rapid release and Scheduled release on January 1, 2017
