Microsoft now has six million Windows Insiders

Windows 10 was open to Insiders first

Microsoft has celebrated getting to six million Windows Insider members by taking on the second annual ALS Ice Bucket challenge.

In a video posted earlier, Microsoft CEO Satya Nadella once again accepted the challenge of former NFL player Steve Gleason, who suffers from ALS, and poured a bucket of ice cold water over his head along with Terry Myerson and members of the Windows 10 team.

Over 20 million installs

Becoming a Windows Insider is easy and there are plenty that have decided to remain a part of the program for Windows 10 despite the fact that it is out in all its unadulterated glory.

Windows 10, which was released two weeks ago, has, depending on where you look, already achieved well over 20 million installs and figures released yesterday suggest that it is well ahead of the adoption rates enjoyed by Windows 8 in its first six months, let alone two weeks.
