I decided to use WinToolkit 1.4.46 to create an ISO with integrated updates and drivers. But I don't know if I did it correctly because in the end it was trying to install updates ON MY SYSTEM instead of applying them to the extracted ISO files. Then it did the same for DRIVERS. NO updates or drivers were applied to the damn extracted files and no integration was possible afterwards. Now I am stuck and I don't know WTH is going on again, but I have a FileRepository folder in System32\DriverStore directory that takes up over 25GB! Please tell me I can delete all that without erasing all my currently installed drivers? I also bet that when I tried to apply updates to the extracted ISO files, the damn WinToolkit applied to my system again! Where would these extra updates be stored? Can I delete them?
