Microsoft has begun to encourage people running Windows 7 and 8.1 to install Windows 10 as a “Recommended Update” in the Windows Update application.

A few months ago, Microsoft said that it would start to do this “early” in 2016, and now it’s happening.

“As we shared in late October on the Windows Blog, we are committed to making it easy for our Windows 7 and Windows 8.1 customers to upgrade to Windows 10. We updated the upgrade experience today to help our customers, who previously reserved their upgrade, schedule a time for their upgrade to take place,” a Microsoft spokesperson told VentureBeat in an email today.

Because this is not a mandatory update, Windows users can stop their machines from going ahead with it. And users can undo the update within 31 days. Earlier, Microsoft was automatically downloading Windows 10 on people’s PCs in order to speed up the installation process, or in cases when the option to update to Windows 10 was checked by default, triggering undesired upgrades for some people.

Last month Microsoft said Windows 10 has upward of 200 million users. Windows 10 now has more than 10 percent market share, according to data from Net Applications.
