Approved Porting Providers

Please NOTE: Microsoft no longer adds new ports to this list. That program ended in 2023. This list includes approved Ported Technology Providers that have developed WMT for various microprocessors and were tested prior to 2023. These older ports of WMT have all passed quality testing by Microsoft, and their inclusion on this list constitutes written permission from Microsoft for an Authorized OEM to use pursuant to their agreement with Microsoft. Companies now do self testing and can provide results directly to customers.
