But remarks made recently by Microsoft's top executive, as well as suspicions raised by customers and software consultants, suggest that Microsoft keeps its licensing complicated for a reason, and that it has no plans to make it any simpler in the foreseeable future.

CEO Steve Ballmer was asked earlier this week at an event in London when Microsoft will simplify its licensing, according to several reports. His response: not anytime soon. "I don't anticipate a big round of simplifying our licenses," Ballmer was quoted as saying. "Every time you simplify something, you get rid of something."

While he acknowledged licensing is complicated, Ballmer said those complications sometimes allow customers to use the fine print to save themselves money. Simplifying the process, he reasoned, would cost them that advantage.

In a recent interview, Microsoft Business Division President Stephen Elop also defended Microsoft's licensing. He acknowledged that it can be difficult to contend with, but said customers find it worth the time and money they invest because it brings them products that help them to innovate and lower their costs.

Customers tend to take a big-picture view of licensing, according to Elop -- that is, they look at the value it adds to their businesses overall, rather than dwell on the minutia of individual licenses required for the products they use.

"Customers want the amount they pay to be tied to the value that they’re driving, the usage they’re getting -- that’s why these models are so complicated," he said. "For different customers, these things are measured in different ways.

"What a customer will do generally is take a big step back and say, what am I paying for e-mail? What am I paying for collaboration? And they will make a determination as to whether they think that’s fair value or less than fair value," he said.

Nevertheless, customers grouse that Microsoft's licensing terms -- particularly a requirement that they buy client access licenses (CALs) for each employee who uses Microsoft's business software -- are harder than they need to be. Some are resigned to their fate, as they don't foresee any long-term resolution to what has been a constant problem.

"I would never say that it's easy," said a senior manager at a Silicon Valley gaming company that uses Microsoft's products. While his company is generally happy with the products it uses, he said, "it's always challenging" to ensure his company stays compliant with Microsoft's licensing agreements -- especially when it comes to CALs.
