Hi I am new here,and this is the problem My Windows 7 64 bit home premimum will not 1. sfc /scannow in any mode...2 Windows update will not work and displays error 80073712....3 Cannot install any new programs or software. I have done everything that can be done and was faced with only the upgrade install of windows 7 as a last ditch effort. Well it runs to the point of fully copying files to my computer then it fails and states go online for updates and try again THAT is the PROBLEM ..I ask if this ios the last solution what now? I would do a clean install but then lose all my programs etc thanks Bob
