It wasn't a high bar, but Windows 7 made it.

Consumer retail sales of Microsoft Corp.'s newest computer operating system topped those of Vista by 234 percent on a unit basis within the first few days of launching on Oct. 22, according to a report released last week by the NPD Group.

The report did not include sales to businesses and large organizations.

Sales of Windows 7 performing better than Vista, the previous Windows OS version, was not too surprising. The buzz for Windows 7 was relatively positive and largely void of the savage language that reviewers heaped on Vista when it was launched in January 2007.

This time around, Microsoft also attempted to woo reluctant buyers with discounts and specials, such as a 50 percent discount on a copy of the software when buyers spring for a new PC, or a free upgrade from Vista for those who bought a PC after June 26.

"We definitely saw the results of aggressive pricing," said Stephen Baker, NPD's computer software analyst.

Though helpful for pushing volume, the discounts may have crimped Microsoft's overall revenue from the product. The NPD report was mum on the sales impact on Microsoft's top line.

It may be too early to say if the software would help ignite sales of personal computers. With consumers making do with their old computers or opting for ultra-cheap netbooks, average PC prices have dropped around 20 percent since 2008, Baker said.

Still, the gruesome economy may have helped Windows 7 sales in one respect, according to Richard Shim, a PC analyst with IDC.

"Usually upgrades are not very popular. People have tended to buy new PCs when new operating systems come out," Shim said. "Windows 7 seems to be an exception. One reason is that it can work well with older computers because it's designed to be streamlined."

In other words, instead of spending $500 for a new computer, some consumers are springing the $120 to $220 Windows 7 upgrades and souping up their old machines.
