Vista Clean Install Using Anytime Upgrade Disc PC manufacturers often do not send an actual Vista disc. Therefore, you'll have to follow these instructions. The secret to this is obtaining the Anytime Upgrade disc. From what I can gather, it's a vendor-neutral OEM disc containing all versions of Vista, designed to be used by consumers who intend to upgrade their existing version of Vista. I ordered the disc from Amazon for less than seven dollars. I'm sure I will put it to good use when removing bloatware and performing clean installs for friends and family.
