Each hard disk drive (even a USB-Stick) has a volume ID (like a Serial Number). To view a drives current Volume ID you can just perform a dir <drive>: and the volume Serial Number is shown on the second line down, e.g.
Volume in drive E is system
Volume Serial Number is BC09-8AE4
The Serial Number can be changed with tools and if a drive is imaged, the volume ID is also imaged
Pros/Cons
+ Always available and always works
+ Works in single user and network environment
- After reinstallation of Windows, the volume ID changes
- Volume ID’s are always the same when a image tool is used to set up a drive
- Allows several installations on the same machine.
Recommendation
• | Good for applications used by home users because the criteria is always available |
• | Only choice if the license file is stored on a memory stick |
