WinNTSetup is your gateway to advanced, pre-installation Windows modification. This straightforward application lets you open and edit Windows installation files (from ISO, WIM, or VHD sources) to apply a wide range of customizations. You can pre-install software, change default settings, integrate critical updates, and optimize the system for performance or specific use cases—all before the OS touches your hard drive. Its reliable, no-frills approach makes it a trusted tool for IT departments, tech enthusiasts, and anyone who wants their Windows installation to be uniquely theirs from the very first boot.
