Windows 11 is available to everyone. Microsoft announced its new operating system at a dedicated event on June 24, with a big design overhaul and native Android app support among the biggest changes.
It's been available for download since October 5, but most Windows 10 devices will have to wait until 2022 to get the free upgrade.
