Confirmed: Certain Server Roles/Features, like WindowsServerBackup is fully compatible with Windows 10 ServerRdsh without the need of Server certificates.
Yes, it is not bad. But sooner or later, all might be replaced by CU, And not compatible with some latest builds.
1. KMS activator is another thing, nothing to do with patching Windows System files. 2. 17639 Server.
Is not patching but replacing files.. to activate with KMS (locally) you have to replace 1 system dll. Is fact. KMS VL ALL uses this approach.
I use only QAD hooker, which injects KMS activator into SppExtComObj.exe running in memory, NOT patching. And it automatically goes up/down together with SppExtComObj.exe, not running all the time.
I try to rewrite it to use memory patching instead.. slshim good because of productpolicy mod + activation
