It keeps trying to update from 8.1 to Windows 10 (which I want it to do), however every time says that it could not complete the update and rolls back to 8.1. I've run sfc /scannow multiple times including in safe mode and I've even gotten to it say it repaired the errors, however it still will not update to Windows 10, nor will it install Windows Updates giving the error: 800703F1. It will also not install drivers for the iphone and rarely recognizes USB devices without going through the Device manager and manually updating the drivers. The error I'm getting with the manual update of the iphone drivers is: the configuration registry database is corrupt. Any help would be greatly appreciated by the wall that I've been banging my head against.
