There's not going to be a release of any consumer editions of Windows Vista but [tag]Microsoft[/tag] are hoping that stickers will help jittery buyers. These stickers will be used to mark "[tag]Windows Vista[/tag] Capable" PCs and you should be seeing them in the shops real soon.
What is a "[tag]Windows Vista Capable[/tag]" PC? To be eligible to display a sticker, the PCs must pass certification requirements for the Designed for Windows XP logo plus some extra hardware requirements. Specifically they must have a modern CPU, at least 512MB of RAM and a DirectX 9 capable graphics card.
