Hi all, Just curious, I have a MAPS account and access to MS Partner Network ISOs I assume these ISOs are different from VL, OEM and Retail versions? Are there delta's available to convert, say, Windows Server 2012 R2 Essentials (part number: X19-59894) to an OEM ISO and use the Daz tool? Or can I just use one of the OEM SLP keys at install and then use tool? Obviously I have access to the keys for each product and they work fine, just interested if the ISOs can be used in any other way. Many thanks!
