How is that relevant?
As I said I would be using the win7 disks to reformat my hard drives to ensure they are clean of any malicious code so I can reinstall Win 10 from a USB which could otherwise be infected the moment it was attached to my PC and thereby re-infect my system after formatting. I have already attempted resetting the system and the problem appears to be persisting. It may be that Steam changed something in their VR Dashboard that is causing the problem or it may be malicious code? But I need to be certain that my system is clean.
