After you have entered your details you will be prompted to set a

password. This prevents anybody else from gaining access to your

branding details or changing them. Optionally, for extra security

Electronic Fingerprinting can be set such that this same password is

requested every time the computer is switched on.

Note

You will be able to change any of the items in your branding details by

running the Electronic Fingerprinting application later and entering the

correct password. This would be necessary, for example, if you moved

house.

Until you have entered your branding details the Electronic

Fingerprinting application will automatically run each time

Window 95 or Windows for Workgroups starts. Thereafter,

Electronic Fingerprinting can be run by selecting its icon which is

displayed:

•

At the top of the Start bar menu, in Windows 95.

•

In the Apricot group, in Windows for Workgroups.
