Why has Vista Home basic been left off of the eligible upgrade paths?
The major lesson learned from the last Windows Upgrade Program was: Keep the Program Simple. Thus, only Like-to-Like upgrades are supported under the Program. So Windows Home Basic is not in scope for this program as there is no “like” version of Windows 7 in mature markets. Additionally, not all Windows Home Basic PCs meet the Windows 7 Hardware requirements – where as all Logo-qualifying versions of Windows Vista Home Premium, Windows Vista Business, and Windows Vista Ultimate WILL meet the Windows 7 hardware requirements.
