As has been the case with Windows 10, after launch, there is likely to be a gradual rollout of Windows 11 to Windows 10 PCs that are capable of running the upgrade.
That could take a number of months: Microsoft said that this process is likely to be “continuing into 2022” and generally it’s the newer PCs that get the upgrade first. When it arrives on your PC will depend on a number of factors.
The company plans to use “intelligence models that consider hardware eligibility, reliability, metrics, age of the device and other factors” to roll it out to additional in-market PCs. It will use Windows Update to notify Windows 10 users when their devices are eligible to move to Windows 11 (and, as ZDNet’s Mary-Jo Foley points out, if you aren’t interested in going to Windows 11 you can stay on Windows 10, which Microsoft will continue to support through October 14, 2025).
But for those who can’t wait for October 5 general availability — which historically has been made for ‘seekers’ or those who choose to manually update through Settings — there are the preview Windows 11 builds that are rolling out now.
But remember — these are preview versions and not the final version. That means there may be bugs or features that may be missing or don’t work very well. That means you should only run a preview on a test device if you have one, and not on your primary device, in case things go wrong.— October 11, 2021
