Do you have an issue to register your windows phone 8 for development because it claims another device with the same name is already registered and you have to rename the device with a unique name. The message: “The device name is already in use by this account”.
Well the solution is simple – change the name, but how?
Trying to that from the device will be unsuccessful, you will just be able to see the name in About menu but not change it.
The actual solution is not that intuitive, – you need to change the name from the File Explorer.
Funny Windows it is!
