I have extracted the "pkeyConfigData" Part from the "pkeyconfig.xrm-ms" (RTM-Build) and found this: Code: <pkc:ActConfigId>{8dffd6e4-0497-4c35-b7d7-e47cf464cf30}</pkc:ActConfigId> <pkc:RefGroupId>170</pkc:RefGroupId> <pkc:EditionId>Enterprise</pkc:EditionId> <pkc:ProductDescription>Windows 7 Enterprise Retail:TB:Eval</pkc:ProductDescription> <pkc:ProductKeyType>Retail:TB:Eval</pkc:ProductKeyType> So there could be a Enterprise Eval avaible in the Future?!?
