Q: I have volume licensing on my machines. Can I purchase machines without Windows licenses to avoid paying twice?

A: When you have volume licensing (and, potentially, rights to editions like Enterprise), you're not paying again for licenses. Essentially, the volume licensing agreement requires an existing valid Windows license that the volume licensing upgrades. It's therefore important that even if you have volume licensing, you purchase devices with valid licenses. Or you'd have to purchase retail versions, which would be more expensive than what you get from an OEM with a new PC.
