Determine product compatibility with Windows Vista
When you search or browse the Compatibility Center, you'll see four different compatibility icons:
A green check mark indicates the product is compatible with Windows Vista
A yellow caution icon indicates that the software publisher offers a free or fee-based upgrade or solution for compatibility with Windows Vista
A red cross shows the product is not supported on Windows Vista
A black question mark indicates we do not have information for this product yet
The default view is 32-bit Windows Vista compatibility status. To view 64-bit Windows Vista compatibility status, click the 64-bit filter on the results page or the 64-bit tab on the product details page.
