Microsoft has announced its flagship operating system Windows 8 has passed 100 million licenses sold across its initial six months on the market.
The figure puts the new OS on par with its predecessor Windows 7, which accumulated the same figure across the same length of time.
Despite the figures, Tami Reller, chief marketing and financial officer for Microsoft, stated that the numbers could have been higher, citing a lack of touch devices hindering the sales.
"If there had been more touch devices in the market, it would have been even more," said Reller during an interview on Microsoft's official blog.
However, Reller went on to highlight that the situation should become more favourable by July and the beginning of the back-to-school selling period as a wider variety of Windows 8 enabled devices are available.
Following its launch last October, Windows 8 scored 40 million sales throughout its first month on the market, whilst upping the figure to 60 million in January of this year.
Reller went on to state that the remaining 40 million licenses have been made up predominantly by sales of new PCs rather than existing Windows users upgrading to the new OS.
In addition to the sales of Windows 8, Microsoft also moved to address Windows Blue.
Despite confirming the existence and codename of Windows Blue, the firm didn't offer up any further information on the update, other than it would be available before the end of 2013.
