5 Windows license codes, 5 activations available per code. This should be a weekly giveaway item or something where only 25 people win the codes. It should not be posted in the same section as the other free windows sharewareonsale software items.
If there is a limited number of activations per license, the registration should be completed with the software vendor so that your readers are able to get their own unique registration/license code. You are normally good about this type of thing, but this time, this is an epic fail.
