In the first post pwnphpbb wrote "The Unique Computer ID, is a Unique ID given to each computer after an install. It would also have to be changed. Whereas the WID is a simple 5 digit numeric number, the computer ID may have some sort of algorithm to it. It's not Base64, if anyone has any ideas, let me know."

Offhand I can think of two ways of getting data about the uniqueness of the Computer ID:

1) do a regular install. check ID

2) do a second install on a different, preferably portable, browser. check ID

3) compare the two IDs.

Second method:

1) install a Virtual Machine. install toolbar (isloated from the real machine). check ID.

2) leave Virtual Machine. install toolbar (with real machine). check ID.

3) compare IDs.
