Microsoft says it will share parts of its Vista code to security software firms to enable their products to work smoothly with its Vista operating system.
The firm said it will show to Symantec, McAfee and other security firms the kernel of the 64-bit version of Vista so that they know how to build products for it. They had access to the kernel in the past until Microsoft redesigned its software to block them.
The codes are part of changes Microsoft said last week it would make after the European Commission said it had concerns that Microsoft´s design of Vista could push some software makers out of the market.
Jonathan Todd, Commission spokesman, said that that The Commission will keep a close eye on how Vista develops in the marketplace and will look into any complaints from software vendors.
Microsoft´s Ballmer said he believed the announced changes would satisfy the EU executive, according to Reuters.
