Hi Coach - when you say "lock down" what security issues or concerns are you intending to address? I like DHK's pick of TrueCrypt for encrypting your data, but you may have other concerns as well re: access to the computer on-site or via the internet. Curious as to what you need to secure... - DH
Yes you can lock you computer other than the normal windows password. You can install this software "Inteset Secure Lockdown v2".Secure Lockdown™ removes the Windows Desktop functionality and unwanted keystrokes and allows your main application to run exclusively.
