No risk, 100% guaranteed
All used licenses sold by us are 100% legally purchased by us. These are licenses once sold by Microsoft, purchased by us from these users. This is guaranteed by license administrators, who check each individual license for provenance and right of use, thus fulfilling documentation obligations. So if you buy a re-used license from us, there is only 1 difference with 100% new. The lower price!
You buy not only the software key from the Application Warehouse, but also the official Microsoft user license. You will be the only registered owner, and the only user with this unique license number. So you are 100% owner after purchase, taking 0% risk with your purchase. However, for a much lower price than you are used too.
