Windows 7 Not Getting a Service Pack 2
It took three years for Microsoft to release an SP2 update for Windows XP. As of this month, it's been three years since the release of Windows 7 in October 2009 and there doesn't appear to another Service Pack in sight. And while not confirmed, The Register claims to have received word from sources close to Microsoft's sustained engineering team, which builds and releases Service Pack updates.
Service Packs are handy because they contain numerous security and performance updates all rolled into one, saving IT managers and home consumers time when it comes to patching up Windows and making sure they're up to date. On Microsoft's end, putting together Service Pack releases is both expensive and time consuming, which could be the other motivating factor in not releasing an SP2 update for Windows 7.
