The only reason I began this was because the other day my friend had suffered Internet issues which had just required a Windows Network Reset and it fixed his internet speeds immediately and then today (Monday 16th February) my other friend was suffering from some broken Windows System Files and had to manually get each DISM command and the SFC command from the web and he said he wished there were a simple GUI for it so I was just going to slop something together but I really got into it after I saw how successful AI was at building the application and making it work and I was so happy that I had to finish it to the end and now I'm really happy with it and I hope it helps anyone with corrupt Windows System files!
