Yeah, you were right! I didn't place the MUI in the /explorer7/en-US, it was rather in the explorer7 directory. Now with the old explorer I'm wondering how can one connect to Wifi, since the network icon doesn't have that function like in windows 7 and the right menu isn't anymore. And would the windows 8 explorer work in windows 7 ? Not that I want it, but just a testing question. Thanks!
