Sorry for the abundant typos, my wireless kb has its own mind and spelling.
What they will request is to have a look at the OS registry and the program list at the control panel add/remove applet.
They normally won't check folder by folder to see what is stored in your HD.
Just uninstalling apps. might not be enough, any trace of them being there previously should be manually removed. Get someone versed in this practice and not just anybody who says he knows how to access the registry editor.
The guy who does the friendly inspection is a lower grade techie. Quick in and out. Smile and offer coffee. Will list all computers and take note of several apps and OS for each machine. Spends a few minutes looking at each, not many. At the end you sign a note stating that X machines were inspected and wait to hear from them.
The other team is another story. Be prepared.
Once you made their list, they will come back in a few years just to check if you have updated/expanded your operation.
