Enthusiasts quickly discovered they could use tools like Rufus or Microsoft’s own USB/DVD Download Tool to write the ISO to a USB flash drive, slashing installation time from 30 minutes (DVD) to under 10 minutes (USB 2.0) or 3 minutes (USB 3.0). More advanced users learned to "mount" the ISO natively in Windows 8 and later, but in Windows 7 itself, third-party tools like Daemon Tools or Virtual CloneDrive were required to mount the ISO as a virtual DVD drive.
