Adoption of Windows 7 continues to grow, with the weeks-old operating system accounting for 4 percent of PCs accessing the Web over the past weekend. By contrast, it took Windows Vista seven months to reach that level.
The new operating system tends to do better on weekends, the time when consumer use accounts for more of the market and then share dips back somewhat as the work week starts. Market researcher NPD said last week that boxed copy sales of Windows 7 were also outpacing those of Windows Vista in its initial days on the market.
Microsoft has also said it is seeing strong interest from businesses, although typically corporations take many months to test a new operating system before deploying it widely.
