As of June 2025, Windows 10's market share has decreased to 48.9 percent from 53.2 percent the previous month, while Windows 11's share has increased from 43.2 percent to 48 percent. Earlier versions like Windows 7, XP, and 8 have significantly lower shares at 2 percent, 0.4 percent, and 0.3 percent, respectively. In Russia, Windows 10's market share slightly decreased from 74.8 percent to 74.6 percent, with Windows 11 at 19.6 percent. The decline in Windows 10's market share is attributed to the upcoming end of support in October 2025, prompting users to switch to Windows 11. Tom's Guide suggests using the Windows Backup feature for continued updates on Windows 10 after support ends.
