Reuters reports Russia's anti-monopoly service has launched a probe of Microsoft over cutbacks in supplies of Windows XP in Russia.
The agency said it thought Microsoft had violated antimonopoly legislation by cutting delivery of Windows XP to Russia both separately and pre-installed on personal computers, as well as in its pricing policy on the product.
"Analysis of the market for various operating systems shows that the transfer to the new Windows Vista operating system is occurring while demand for the previous operating system, Windows XP, continues," the service said.
"Demand for separately packaged and pre-installed verions of Windows XP is also confirmed by retailers and the number of orders from the government."
It said it would consider the case on July 24, 2009.
