The upgrade arrived a few days after the actual anniversary of the Windows 10 launch on July 29, which is when Microsoft terminated the free upgrade offer. Those who had downloaded Windows 10 by then received the Anniversary Update at no cost.
Microsoft first announced the Anniversary Update at its 2016 Build developers conference. Executives demoed some of the key features, which focus on digital inking capabilities, Cortana, and security.

Windows Ink, a new digital inking hub, is designed to improve digital pen use in Windows 10. Users can quickly jot down notes, scribble on screenshots, or mark up documents in core Windows apps like Word and PowerPoint.
Cortana will be available above the lock screen, so users can ask questions or set reminders without unlocking. Security advancements include Windows Defender, a free anti-malware service, and Windows Hello built into Windows apps and the Edge browser.
Microsoft is also giving Edge a boost as part of the Anniversary Update with power-saving improvements designed to improve battery life. Extensions arriving in Edge include AdBlock, AdBlock Plus, LastPass, and Amazon Assistant.
Despite the many changes Microsoft packed into the anniversary OS release, it's not giving businesses much urgency to upgrade, as discovered in a survey of more than 300 IT pros conducted by systems management specialist Adaptiva.
The survey discovered 63% of businesses plan to hold off on upgrading for at least six months. While more than three-quarters (76%) of respondents claim the Anniversary Update isn't giving them to change the date, 39% of large businesses say they will migrate sooner because of the release.
The Windows 10 Mobile Anniversary Update was delayed beyond the Aug. 2 launch. Microsoft later confirmed on Twitter the mobile version will be available on Aug. 9, reported Neowin.
