The changes should also let users of the simplest Windows 7 build also change their desktop background, a feature that also wasn't an option in the past.
Why Microsoft would loosen its restrictions isn't mentioned in the seeming leak but may have its roots in the company's desire to maintain the control it recently gained of the netbook market. It won the market largely by heavily discounting Windows XP, eliminating most of the Linux cost advantage. Imposing major limits on the software bears the risk of steering some netbook buyers towards Linux, where those limits don't exist. Newer Linux variants like Ubuntu Netbook Remix are tailored just for the ultra-small computers.
Windows 7 Starter will nonetheless maintain some important restrictions, such as the absence of interface elements that require Aero Glass (such as "peek") and touchscreen support; as such, it's likely to increase the cost of convertible tablet netbooks and others with built-in touch.
Microsoft hasn't commented on the accuracy of the report.
