The Service Desk Edition of Microsoft Office is almost identical to the Standard Edition, but is sold by service desk retailers. It has the same programs and licensing, but is packaged in a slimmer case.
The Microsoft Office Service Desk Edition is a version of Microsoft Office 2007 Home and Student. Therefore, it contains Microsoft Word, Excel, PowerPoint and OneNote.
The Service Desk Edition of Microsoft Office 2007 Home and Student is licensed for personal use on up to three PCs. It is not licensed for business use.
The key difference between the Service Desk Edition and Standard Edition of Microsoft Office is packaging. The Service Desk Edition is sold in a plastic case similar to a DVD case, while the Standard Edition is sold in a cardboard box. The smaller case allows retailers to hang these editions from a peg at their service desks in order to advertise upgrades of Microsoft Office.
