Microsoft introduced the retail version of Windows Vista and 2007 Office System on Tuesday to reach 18 million customers in a month.

Available in four consumer editions, Windows Vista will be sold through 1,500 outlets in India and is priced comparably with its last offering Windows XP, Microsoft India Chairman Ravi Venkatesan told a news conference in Mumbai.

The genuine Windows Vista Loaded PCs in India will retail at a starting price of Rs 22,000 while Microsoft 2007 Office consumer edition starts at Rs 6,000.

The four editions are Windows Vista Ultimate, Windows Vista Home Premium, Windows Vista Home Basic and Windows Vista Starter.

The Microsoft 2007 Office is available in two editions of Office Home & Student 2007 and Office Basic 2007.

The differentiator in the latest operating system is on four counts of search, security, connectivity and ease of usage, Microsoft India Managing Director Neelam Dhawan said. 

The company expects to reach 18 million customers in the next 30 days of the launch. The company has already sold nearly nine lakh licenced editions to corporates.
