Windows XP is still in use on millions of machines, and has more active users than Windows 8 despite Microsoft ending support for the system a year ago.
Data from Netmarketshare shows that the user base for XP was 16.94 percent at the end of March. This compares with 58 percent for Windows 7, which remains by far the most popular Microsoft operating system in use.
However, more notably, the Windows XP user base is higher than that of Windows 8.1 at 10.55 percent, and Windows 8 at 3.52 percent. Even combined, the Windows 8 user base is still lower than that of Windows XP.
The March 2015 figure for XP does represent a decline in use over the past 12 months. Data for March 2014 showed that it had a base of 27.69 percent.
This is a fall of just over 10 percent, but it is still a far higher figure than Microsoft will have hoped and will represent many millions of machines running Windows XP connected to the internet.
V3 contacted Microsoft for comment on the figures but had received no reply at the time of publication.
The 8 April 2014 deadline saw Microsoft urge as many people as possible to move away from XP, warning of major security risks in failing to do so.
Microsoft did rather undermine these warnings by issuing a fix for XP soon after the deadline passed, although no more updates have since been issued. Furthermore, despite the warnings, few security problems with XP have surfaced.
Regardless of this, many individuals and businesses clearly failed to heed this advice and have stuck with the platform.
Many more may well be engaged in migrations, but these can often be time-consuming and complex, meaning they are still using XP even as they plan to move away from the operating system.
The UK government has been one major organisation to stick with XP, after reports last year of a hefty £5.5m deal to provide a one-year support extension for public sector organisations still using XP.
