This small programme blocks the eject button at almost every CD/DVD drive and gives the user the power of controlling the CD/DVD drive by a small icon at the windows system tray.
very good program cdrom-lock.
An outdated and glitchy software. i would go with LockCD (look it up on sourceforge or google)
For Win7 64 bit, may need to install msinet.osc first (google "msinet.cab activex" for a d/l link) Then run in WinXP 32bit compatibility mode. The second step may be all that is necessary, but this was the process which fixed the missing msinet.ocx errors for me. Works great!
