It is not that easy to put together a full featured Common Lisp environment on Windows. It can take much time to get everything running, especially if you are new to Common Lisp.

For those of you who experienced difficulties in that task, LispStick! could be a very convenient solution. Lispstick! can be unpacked into a directory of choice in your file system or even onto an USB-stick, to be available to you, if you only have access to some windows box.
