Microsoft has been fairly secretive about its upcoming Windows 10 launch. The same cannot be said for AMD’s Chief Executive Lisa Su, who was caught on record saying that Windows 10 will launch in late July.
We all knew that Microsoft was launching Windows 10 in the summer. But thanks to Lisa Su, we now have a better idea of when that launch will take place.
During AMD’s quarterly earnings call late last Thursday, the company CEO said the following:
“With the Windows 10 launch at the end of July, we’re watching, sort of the impact of that on the back-to-school season, and expect that it might have a bit of a delay to the normal back-to-school season inventory build-up,”
That question was answered in response to an industry analyst. Oops!
So unless Microsoft changes its plans, or Lisa was given false information, we can expect Windows 10 to launch between July 20 and 30, 2015.

When Will We Know the Official Release Date?

If you like to avoid leaks and hear news straight from the horse’s mouth, then you’ll want to wait for the official announcement from Microsoft.

In 2012, Microsoft announced the release of Windows 8 about 3 months ahead of time. In 2007, Microsoft announced the release date for Windows 7 4 months ahead of time.
Both of those operating systems were launched in October.
Based on that release announcement schedule, Microsoft should have announced the official Windows 10 release date already. We’re less than 3 months away from the end of July.
After announcing Windows 10’s release date, Microsoft will then announce the Release To Manufacturer (RTM) build, which is the version of the OS that ships to PC makers so they can preinstall it in brand new Windows 10 machines.
The annual Build Developer conference took place this past week, which is where many people expected Microsoft would announce the Windows 10 release date. They did not, which might suggest that Microsoft is currently unable to pinpoint an exact release date.
