The report shows that 27% of systems accessing net applications and websites are still operating on the nearly 15-year-old Windows XP, meanwhile Windows 8 and 8.1 comprise approximately 11% of the marketshare. Windows 7 sits at 48.77%,
As the graphs are updated, we've seen Windows XP shrink as Windows 7 grows, with very little noticeable movement to Windows 8's marketshare. This is furthered by the fact that migration to Windows 7 from XP is a bit easier (regarding data retention), so fewer users would have to perform a clean install. That stated, it's strongly-recommended that a clean install is performed rather than an actual upgrade install, given the amount of clutter left behind.
