More -We’re getting closer to the general availability of Windows 7 on October 22nd, 2009, and to the final review of the operating system, for which I’ll use the Ultimate version, so make sure to tune in next week. For the time being, however, I played around with the closest thing to the Ultimate SKU when it came down to Windows 7, namely the Enterprise version. Just as the Professional SKU, Enterprise is not designed for end users. In fact, customers won’t even be able to acquire Windows 7 Enterprise except via Volume Licensing, and they would already need to have a Software Assurance agreement signed with Microsoft.
