An anonymous reader writes "Microsoft Corp. acknowledged Wednesday that it needs to better inform users that its tool for determining whether a computer is running a pirated copy of Windows also quietly checks in daily with the software maker. The company said the undisclosed daily check is a safety measure designed to allow the tool, called Windows Genuine Advantage, to quickly shut down in case of a malfunction." The EULA is suppose to disclose this daily call-in feature. Lauren Weinstein, who is co-founder of People for Internet Responsibility, was one of the first people to notice the daily communications to Microsoft. Report from Yahoo.com"
