According to Microsoft's Windows Phone Twitter support account, this error is real but normal users will never see it. However, those of you who like to mess around with your handset running Microsoft's Windows Phone mobile operating system might see this amusing error. After all, how can you insert a Windows installation disc to a phone? One thing this error proves is that Windows Phone 8 does in fact run on the NT kernel.
