Google believes that Windows is too insecure, but Microsoft defends its operating system.
Google vs Microsoft 001 Microsoft Responds to Googles Criticism of Windows

As you have probably heard by now, Google has, according to several sources, decided to relocate all its employees to other operating systems than Windows. It is allegedly the Chinese attacks in December last year that have led Google to decide to abandon Windows.

Google believes that Windows is too insecure, but another reason may be that the firm develops its own operating system, Chrome OS, which is confirmed to be released later this year.

Windows Communication Manager Brandon LeBlanc has responded to criticism from Google in Microsoft’s official blog. And he  denies, not surprisingly, that there would be reason to worry about security in Windows.

When it comes to security, even hackers admit we’re doing a better job making our products more secure than anyone else. And it’s not just the hackers; third party influentials and industry leaders like Cisco tell us regularly that our focus and investment continues to surpass others.

He fires back at Google and reminds them of their own security problems.

There is some irony here that is hard to overlook. For starters, check out this story from Mashable a few months ago where it was reported that Yale University had halted their move to Gmail (and their move to Google’s Google Apps for Education package) citing both security and privacy concerns.

In the blog he also refers to Windows Update and Microsoft Update, that delivers security updates as quickly as possible.
