Microsoft, in a tweet late last week, announced that while Windows 11 launches later this year in 2021, the operating system won't be made available as a free upgrade to existing Windows 10 users before the first half of 2022. This would mean that existing Windows 10 users wanting to try Windows 11 out this year, might have to purchase a retail or OEM license to Windows 11. "Windows 11 is due out later in 2021 and will be delivered over several months. The rollout of the upgrade to Windows 10 devices already in use today will begin in 2022 through the first half of that year," tweeted the official Windows handle.
