Keeps Windows installer packages safer Traditionally, the original editions of Windows come on a CD and utmost care is required when handling the disc. It can be safely stated that this prolongs the life of your Windows package, seeing as compact discs are highly sensitive, whereas USB flash drives offer you more flexibility. WinToFlash accomplishes an amazing task: it extracts the contents of a Windows installation and transfers it on a bootable USB drive. Use your USB flash drive to transfer Windows installation packages from CD or DVD to use whenever a fresh setup of the operating system is required.
