The U.S. government will join select partners of Microsoft in receiving security patches up to a month before they become generally available. The early-access program, already available to some customers, provides beta test versions of patches so customers can be prepared when vulnerabilities are publicly disclosed.

Microsoft signed a $500 million software deal with the Air Force last year, which stipulated that the Air Force will join the Security Update Validation Program and test patches before they are officially released. In turn, the military will become a beta tester for Microsoft's updates.

Instead of patching they have to think of switching some capacities to Linux as Germany, China and many other Europien (smart) countries are doing.
