Microsoft has come to the aid of an embattled Wall Street, having reported a 79% increase in the lastest quarter's profits and raised its profit outlook for the full year. 

IBM also posted good results last week, giving analysts cause for optimism, but Apple's poor results and Intel's cautious outlook led to market jitters earlier in the week.
Microsoft had a good quarter on sales of the Vista operating system and Office software.
In addition, it was having success with its anti-piracy campaigns.
The software maker reported net profit for the second quarter of $4,7-billion, up from $2,6-billion a year earlier.
The company now expects revenue for the full year to be between $59,9-billion and $60,5-billion, compared to previous forcasts of $58,8-billion to $59,7-billion.
