Windows 7 hasn’t even hit the Release Candidate test phase, but already analysts at Gartner are advising business users they shouldn’t plan to wait for Service Pack 1 (SP1) to arrive before planning deployments.From a March 12 research note by Gartner analyst Michael Silver (a link to which Microsoft is distributing to various press folks): “The first Service Pack for Windows 7 is not necessary for the operating system’s stability and security readiness. However, organizations likely won’t be ready to deploy Windows 7 before SP1 ships, so they will include it in their initial deployments,” writes Mary Jo Foley.
