The OLAP reports may or may not show the distinction between the different editions for Windows with SQL Server.
Windows with SQL Server has several Editions > Windows with SQL Server Standard, Windows with SQL Server Enterprise and Windows with SQL Server Web.
The difference is mainly from the origin source of data in the report you are viewing.
In the OLAP reports, the distinction is derived from CUR LineItemDescription.
Other reports such as the Assets reports or the Usage/EC2 Instance Hours report, derive the distinction from our asset collection system which leverages the AWS SDK interfaces to regularly fetch data to describe instances.
