Rated 5 out of 5 stars

Excellent for cafe's minus one little caveat.

Please add option to disable file browsing through Firefox -> New Tab -> Open File Menu list option as this allows users access to the filesystem and can open a command prompt by right clicking cmd.exe and run as admin.

Otherwise my favorite lockdown tool. Installed on all of my PC's 25 and installed on my in-law's computer. You are the man! If you want or need help let me know!
