Bungled branding of the new Windows Live Internet services has hurt Microsoft and could affect its chance to play catch-up with Google, analysts said on Friday. On Thursday, Microsoft lowered its sales forecast for its Internet services business for the full year from 11 percent to between 3 percent and 8 percent. It also acknowledged that its search market share has dropped. Windows Live Search saw its searches drop nearly 10 percent from a year ago, while Google’s rose more than 22 percent, according to figures released this week from Nielsen/NetRatings. Google has 50.8 percent market share, followed by Yahoo at 23.6 percent and Microsoft with only 8.4 percent.
