Microsoft today announced that Windows Virtual Desktop (WVD), its Azure-based system for virtualizing the Windows and Office user experience it announced last September, is now generally available. Using WVD, enterprises can give their employees access to virtualized applications and remote desktops, including the ability to provide multi-session Windows 10 experiences, something that sets Microsoft’s own apart from that of other vendors that offer virtualized Windows desktops and applications.

In addition to making the service generally available, Microsoft is also rolling it out globally, whereas the preview was U.S.-only and the original plan was to slowly roll it out globally. Scott Manchester, the principal engineering lead for WVD, also told me that more than 20,000 companies signed up for the preview. He also noted that Microsoft Teams is getting enhanced support in WVD with a significantly improved video conferencing experience.

Shortly after announcing the preview of WVD, Microsoft acquired a company called FSLogix, which specialized in provisioning the same kind of virtualized Windows environments that Microsoft offers through WVD. As Microsoft’s corporate VP for Microsoft 365 told me ahead of today’s announcement, the company took a lot of the know-how from FSLogix to ensure that the user experience on WVD is as smooth as possible.

Brad Anderson, CVP of Microsoft 365, noted that just as enterprises are getting more comfortable with moving some of their infrastructure to the cloud (and have others worry about managing it), there is now also growing demand from organizations that want this same experience for their desktop experiences. “They look at the cloud as a way of saying, ‘listen, let the experts manage the infrastructure. They can optimize it; they can fine-tune it; they can make sure that it’s all done right.’ And then I’ll just have a first-party service — in this case Microsoft — that I can leverage to simplify my life and enable me to spin up and down capacity on demand,” Anderson said. He also noted, though, that making sure that these services are always available is maybe even more critical than for other workloads that have moved to the cloud. If your desktop stops working, you can’t get much done, after all.

Anderson also stressed that if a customer wants a multi-session Windows 10 environment in the cloud, WVD is the only way to go because that is the only way to get a license to do so. “We’ve built the operating system, we built the public cloud, so that combination is going to be unique and this gives us the ability to make sure that that Windows 10 experience is the absolute best on top of that public cloud,” he noted.

He also stressed that the FSLogix acquisition enabled his team to work with the Office team to optimize the user experience there. Thanks to this, when you spin up a new virtualized version of Outlook, for example, it’ll just take a second or two to load instead of almost a minute.

A number of companies are also still looking to upgrade their old Windows 7 deployments. Microsoft will stop providing free security patches for them very soon, but on WVD, these users will still be able to get access to virtualized Windows 7 desktops with free extended security updates until January 2023. Anderson does not believe that this will be a major driver for WVD adoption, but he does see “pockets of customers who are working on their transition.”

Enterprises can access Windows 10 Enterprise and Windows 7 Enterprise on WVD at no additional licensing cost (though, of course, the Azure resources they consume will cost them) if they have an eligible Windows 10 Enterprise or Microsoft 365 license.
