Is it possible to convert KMS v6 to KMS v5 in Windows 8.1? Latest 8.1 Preview used KMS v5, and RTM is v6.. My (dummy) question is: Can we replace some system files from Preview that will 'convert' RTM to KMS v5, and than use some of old kms emulators? Sounds too simple, but maybe it's possible? I'm not expert in that stuff, so asking some of you about help.. Sorry for bad english.. Greetings, pleXtOr !
