Interestingly enough, 4.53% of PC users are still on Windows XP operating system which had released in 2001. That will likely now continue to be the trend, with Windows 10 steadily growing its share as more users upgrade away from Windows 7 through buying new hardware. According to Net Market Share, however, Windows 10 now has a usage share of 39.22%, beating Windows 7's 36.90% usage share.
Stat-wranglers from NetMarketShare are the latest to declare that Windows 10 has gently given its much-loved (or less disliked) predecessor a nudge toward oblivion, if only by a few percentage points. That's not an easy job, for sure, but considering Windows 10 is now the most popular version of Windows, the complete shift will happen eventually. In an update to the build's list of known issues, Microsoft this week confirmed that the fix also had the effect of breaking both Windows Defender Application Guard and Windows Sandbox (via OnMSFT). That's as of December 2018.
Apparently, we aren't yet done with the Windows 10 October 2018 Update issues.
Microsoft Windows 10 had a great start with 14 million devices adopting the software in less than 24 hours of its release. Microsoft later admitted that it would miss the target.
Back when Windows 10 arrived in 2015, Microsoft famously said it planned to have the OS installed on one million devices by 2018. This is what made it possible for Windows 10 to become the "most popular desktop OS" in December. But now months since its release, the software has failed to gain traction with users.
Except there will. If you're willing to pony up the cash, Redmond will keep those updates coming for another three years via paid-for Windows 7 Extended Security Updates (ESU) through January 2023.
