From the ITC Website:
ITC’s Standard End User License
Rather than license each typeface by printer, ITC licenses typefaces by computer. ITC’s Standard End User License Agreement allows for the installation of any typeface, regardless of format, on up to five (5) computers at one location. ITC typefaces can be printed to any number of printers that are accessed by these five computers, but the typeface may only be permanently downloaded to the hard disk or other non-volatile memory of only one printer. A copy of the complete standard license agreement is displayed during the online ordering process and is included with every font downloaded from our Web site.
You are the End User. Dell is the OEM, and purchased the license for you by proxy. You pay for this in the computer's price.
Copying font files is a little tricky since Win98, as the copy function was removed from the context (right click) menu for font files.
You can use Control-C to copy and Control-V to paste, or use the Copy & Paste commands on the Edit menu in Windows Explorer.
If you give away or sell the system that Bradley came with, you are transferring the license to the recipient if the original copy of the font is still there. You could delete that copy and thereby be declining to re-sell or transfer that license.
