A Microsoft employee who wished to remain anonymous to the public has informed Windows Central that as of 8 AM July 31, the Windows 10 OS has reportedly been installed on a massive 67 million machines, Windowscentral.com reported.

Even more interesting is the claim that Microsoft hit a max bandwidth of 15 Tb/s, topping the previous record of Apple's 8 Tb/s during their last OS push. Microsoft has reportedly reserved up to 40Tb/s "from all of the third-party CDNs combined".

Windows Central has not been able to verify the numbers independently. However, they are within reason. Just 24 hours after Windows 10 began to roll out Microsoft themselves confirmed more than 14 million machines had Windows 10.

Presumably as Microsoft gains confidence in the update process and ability to deliver they would increase the rollout with larger waves.

Regardless, we are confident Microsoft will do a big article sometime in the next few days extolling the number of people now on Windows 10. Their goal is to hit a billion over the next two to three years, so they have plenty of time.
