The Windows 10 Anniversary Update was released to the stable Windows 10 channel back on August 2. Today is September 13, and many Windows 10 users are still waiting for their update. According to an e-mail that some Windows users have received, that update may not be rolled out until November, as reported by Mary Jo Foley.

Staggered rollouts aren’t new. Previous major updates have often taken days to become universally available. But this scale, with three months from start to finish, is longer and more drawn out than has been seen before, and Microsoft is being much more tentative about the rollout than it traditionally is.
