Businesses are still facing compatibility issues with Windows 7 adoption, despite the effort that Microsoft has put in ensuring compatibility with the new operating system.

That's according to automated testing company London-based ChangeBase which has just undertaken a proof-of-concept test of Windows 7 with 20 large users, each containing a few thousand applications. The company found that about that 60 to 80 percent of an organization's applications will need some work before they're able to handle Windows 7 fully.

ChangeBase's managing director John Tate said that software compatibility was still one of the biggest challenges that Microsoft faced in getting their users from XP to Win7, although he agreed that the situation had got better since the launch of Vista. "the leading software vendors have addressed some of the issues," he said. But, as he pointed out, it's not really a Microsoft problem but one for the software vendors and the user companies.
