USB Safely Remove - free 1-year licenses until Dec. 5

For anyone who's interested, they're giving away 1-year licenses.

In the email I got with the license key, I also got a code for 50% off a lifetime license.

I know it stores preferences in %appdata%, so it's not portable, but I think the CLI app usr.exe can be used portably.
