Microsoft promised to launch Windows 10 in the summer, and now the company is revealing an exact date: July 29th. The official date comes weeks after AMD CEO Lisa Su revealed that Microsoft would launch Windows 10 in late July. Microsoft’s aggressive timing means that the company will be looking to finalize its features for Windows 10 very soon. Recent preview builds of the operating system continue to include many changes to features, and a number of issues and bugs.

To get the word out about Windows 10, which is available as a free upgrade for Windows 7 and 8.1 users, Microsoft is also dropping a notification into users' task bars. Clicking on the pop-up brings up a slideshow explaining the benefits of Windows 10 (such as the return of the Start menu, a new browser, and the inclusion of Cortana) before giving users the option of entering their email address to reserve their copy. However, while the free upgrade is certainly generous, some users have complained that the notification is "intrusive," while others say its unexpected appearance made them think they'd been infected with malware. ("I just about went defcon 1 over this," commented one Reddit user.) Still, Apple delivers notifications about its own free upgrades to OS X in the same way, and pop-ups seem a fair trade for not paying to upgrade your operating system.
