Determine Windows Version, Edition and Service Pack OF AN OFFLINE DISK IMAGE
Using the registry alone, how does one detect: The Windows Version (XP, Vista, 7). The Edition (Home Premium, Professional, Ultimate). And The Service Pack level (Beta, RTM, SP1, SP2).

This is because I am repairing on offline system. The Registry of offline systems can be mounted and accessed.
