In excess of 350 million licenses of Windows 7 were sold in the 18 months passed since the platform hit GA, the first 300 million of which by the end of January 2011, but despite being the second most used OS on the market, Windows Vista’s successor is doing a far superior job at protecting users compared to Windows XP.
According to operating system usage statistics from Net Applications there are largely two XP users for each customer running Windows 7.
Yet, according to the recently launched Security Intelligence Report volume 10 from Microsoft, the infection rates for Windows 7 are dwarfed by those of the decade old operating system launched in 2001.
“Infection rates for more recently released operating systems and service packs are consistently lower than earlier ones, for both client and server platforms. Windows 7 and Windows Server 2008 R2, the most recently released Windows client and server versions, respectively, have the lowest infection rates,” the software giant stated.
Previous releases of SIR provided the same conclusions, but smaller market share could have been seen as contributing to lower Windows 7 infection rates.
But fact is that the uptake explosion for Windows 7 was not correlated with a similar increase in the volume of compromised computers.
The infection rate that Microsoft associates to Windows 7 in SIRv10 has been somewhat constant and remained under 4.0 since the end of 2009.
