Windows operating system end of life events are a big deal, with 1.6 billion active Windows devices as of 2024 Microsoft still holds a commanding lead over any other operating system provider. Even though Windows 11 was released almost 4 years ago at this point, it still only represents 28% of the global Windows market share (with 70% still using Windows 10).
There are a lot of reasons for this, from users being comfortable with the Windows 10 interface to many devices that simply aren’t Windows 11 ready (interested in a Windows 11 device in 2025? Here’s our guide).
Users hanging onto a previous version of Windows until the bitter end is nothing new for Microsoft, Windows 7 still had a 12% market share when Windows 11 was released October 2021 (almost 2 years since it’s own EOL date occurred).
In the past, Microsoft has released critical security updates even for systems no longer receiving support.
