validity of operating system

[philou92]

Hi Lansweeper,

in a report named "noimage", you consider that all operating system serial numbers that start with "55440-640" are invalid OS.
Could you explain us why this number is considered as invalid?
I whish to be sure all Windows installation are valid in my company, and I find three different "9 first chars"serial number.

Thanks for help
