As it struggles to gets its software-patch ducks in a row, Microsoft is tinkering with its Software Update Services (SUS) patching service. Late last week, with no advance notice, Redmond added to SUS the ability to push entire service packs to customers. Microsoft is working on its SUS 2.0 release, expected late this year or early next, that will provide mid-size businesses with patches and updates for all products, not just Windows, as is currently the case. It's also working on a mega security-fix rollup, which could potentially be delivered by SUS.
