As we near the release of Microsoft's Windows 7 in October, insiders are now trying to predict just how popular it will be amongst consumers. A recent report suggests it could be very successful indeed.

According to industry analysts IDC, Windows 7 should account for approximately half of all client operating systems shipped to corporate users by the year 2010. IDC predicts that should mean about 58 million copies of the new OS, which is set to ship October 22, 2009.

Vista's Eclipse on Horizon

The prediction means a quick eclipse of Windows Vista and even the long-lasting Windows XP, the operating system many companies have used for years.

Technically, the IDC believes Windows 7 will account for 49.5 percent of all Windows-based operating systems purchased by corporations, with 2007's much-criticized Vista pulling up far behind at 15 percent (totaling about 18 million copies).

Thus far, Amazon.com reports that pre-sales of Windows 7 have been very hot since the online retailer opened sales up over a week ago. (Source: pcworld.com)

Win7: Huge Market Share by 2011 Predicted

If you think Windows 7's popularity in 2010 sounds impressive, then get this: IDC predicts that by 2011, the much-anticipated OS should comprise 75 percent of the Windows-based market, with Vista all but gone at 0.5 percent.

Microsoft's Windows 7 recently moved to manufacturing. The Redmond-based firm has also appointed a new Windows 7 boss, Steven Sinofsky, who will head the $17 billion Windows client division as it approaches the home stretch towards a fall release. (Source: informationweek.com)
