>I have a client that wants to keep people from getting into his files. He's running 95 on a standalone. I was thinking, what if he booted from a floppy and disabled booting from the hard drive by removing or renaming the system files. Sure, if someone had a bootable floppy they could get in, but other than that it's pretty safe. The BIOS on this computer has no security or passwords. Any other ideas?

Like Arnon said, the best way is through the bios. A "keep honest people honest" solution could be a utility that does not allow new users to "log into" 95 via the log in screen at startup. You can find it on the Windows 95 annoyances page (a great page in general, BTW) the URL escapes me right now, but you can find it from my web page....

HTH,
