Windows makes it easy to quickly download files to iPods and other portable storage devices--a little too easy in the minds of many IT managers.

In the next version of Windows, Microsoft will give big companies an easy way to block use of such devices, while making it easier for consumers to connect their home systems to them, a company representative told CNET News.com.

Much has been made of the security risks posed by portable storage devices known as USB keys, or flash drives, music players like the iPod, and other small gadgets that can store vast amounts of data. Some fear that such tiny devices can be used to quickly copy sensitive data off business PC hard drives, or to introduce malicious software onto corporate networks.

"It's a real problem," said Padmanand Warrier, a developer in Microsoft's Windows unit. "That's the feedback we've gotten from IT folks."

To put the new features in place, Microsoft is hoping to move to a common model for how wired and wireless devices connect to a PC in 2006, around the time that it releases the next version of Windows, code-named Longhorn. For consumers, that means that wireless printers, networked music players and other wireless devices should be able to connect to a PC as easily as the USB drives today.
