Final answer:
To prevent a program from automatically launching from a CD, disable autorun on the computer. This is a Windows feature that can be turned off for security.
Step-by-step explanation:
To prevent a program on a CD from immediately launching when inserted into a computer, the security best practice you would want to utilize is Disable autorun. Autorun is a feature in Windows that automatically starts a program and opens a document on a CD or DVD when the media is inserted into the drive. By disabling this feature, you prevent the automatic execution of potentially malicious software that could be on a CD or DVD.
Options like MSCONFIG >Startup Tab, Disable the Guest account, Rename the Administrator account, and Restrict user permissions are also important security measures but do not directly prevent the autorun of programs from CDs or DVDs.
