While its successor - Windows 8 - is set for release next month, Windows 7 has taken the crown as the world's most used operating system.
Figures released by web tracking company Net Applications for the month of August puts Windows 7 at the top of the pile with a market share of 42.76 per cent, whilst XP trails with its 42.5 per cent share.
The seemingly forever-dominant Windows XP has suffered steady monthly decline throughout the past year as its newer counterpart has experienced significant growth.
Ahead of its release next month, Windows 8 has already appeared on the list, amassing a market share of 0.23 per cent.
Meanwhile, the widely disappointing Windows Vista's usage continues to dwindle with a market share of just over six per cent.
Windows' products continue to dominate the desktop market, with a combined market share of 92 per cent.
Apple continues to make steady progress with its own Mac OS X, as its combined user base now outweighs that of Windows Vista, with a total market share of 7.11 per cent.
There is some controversy over the figures themselves, and whether they are entirely accurate.
Rival web tracking firm StatCounter initially reported that Windows 7 had overtaken XP almost a year ago, and tracks its current user base above the 50 per cent mark.
