Google has confirmed that its latest Chrome upgrade will automatically switch from 32-bit to 64-bit on compatible Windows machines. The latter is a much more efficient browser, with greater performance and security. However, some users simply haven’t ditched 32-bit yet.

It might be that you hardly ever use your PC, so you haven’t taken the time to upgrade Chrome in a long time. Or you installed the 32-bit version accidentally because you’re not sure about the difference between the two. But don’t worry, because with Chrome version 58, Google will automatically migrate users to its 64-bit browser.

This version of Chrome delivers improved performance, better memory management, and a more secure experience. However, in order to run it, you will need a compatible computer with a 64-bit processor, at least 4GB of RAM, and a 64-bit version of Windows installed. If your machine does not meet these requirements, then Chrome won’t attempt to migrate.

Google says its 32-bit version of Chrome will continue to be available, so those who need it will still have access to it. If for any reason you don’t want to be migrated to the 64-bit version despite owning a compatible PC, you’ll need to disable Chrome updates, which install automatically by default.
