As the clock turns to 12:01 a.m. in Australia and New Zealand, Microsoft's October 5 rollout of Windows 11 to mainstream users is commencing. Here's what to expect as Microsoft makes its latest version of Windows available to more and more customers.

Who can get Windows 11 today (beginning October 4 at 4 p.m. ET)?
As it turns to 12:01 a.m. on October 5, Windows 11 will start rolling out to the mainstream in each of the more than 190 countries where it will be available. People who buy new PCs from Microsoft and its OEM partners with Windows 11 preloaded on it can get Windows 11 immediately. Some new PCs that meet Microsoft's hardware requirements for Windows 11 also will ship with Windows 10 but will be eligible for an immediate upgrade.

In addition, "seekers" running Windows 10 who have machines that meet Microsoft's hardware requirements (TPM, CPU, etc.) also will be able to download and install it proactively. Users can run Microsoft's updated PC Health Check app to see if their PCs meet Microsoft's hardware bar. To see if Windows 11 is available for a particular device, users can open Windows Update Settings and check for updates. If the device is eligible and deemed ready by Microsoft, the option to download and install will appear.
