The Virtual basic 6 support page has been updated and it states that VB6 runtime is supported in Windows 7 (win7). The following summary is from Source 1.
Since the initial release of this support statement, the Windows 7 operating system has been announced. This document has been updated to clarify Microsoft’s support for VB6 on Windows 7.
VB6 runtime will ship and will be supported in Windows 7 for the lifetime of the OS. Developers can think of the support story for Vista being the same as it is for Windows 7. However there are no plans to include VB6 runtime in future versions of Windows beyond Windows 7.
