Looking forward to Windows 10 when it "launches" on July 29th? You might be waiting a bit longer than that.
Microsoft's ambition for Windows 10 is quite expansive, and that's been no secret for some time. Ambition is tricky, however, when you've got systems that count into the billions to upgrade.
Writing at the Windows Blog, Microsoft's Terry Myerson lays out Microsoft's expectations for the delivery of Windows 10. If you'd already put time aside on the 29th to manage your upgrade or upgrades, you may want to rethink your plans.
"We’ve been really pleased with the strong response to Windows 10 since we kicked off reservations in early June, with millions of reservations. We want to make sure all of you have a great upgrade experience, so we’ll roll-out Windows 10 in phases to help manage the demand. "
"Starting on July 29, we will start rolling out Windows 10 to our Windows Insiders. From there, we will start notifying reserved systems in waves, slowly scaling up after July 29th. Each day of the roll-out, we will listen, learn and update the experience for all Windows 10 users."
The delay applies slightly differently for different versions of Windows
"Windows 10 Pro will be available on July 29, along with Windows 10 Home. Volume licensing customers will be able to download Windows 10 Enterprise and Windows 10 Education on Volume Licensing Service Center (VLSC) starting on August 1."
