WinToHDD is a Windows software that enables users to easily and conveniently install or reinstall various versions of Windows, including 11, 10, 8.1, 8 and more, without the need for a CD/DVD or USB drive.

One of the great features of WinToHDD is that you can reinstall Windows without needing a CD/DVD or USB drive. Plus, it allows you to install Windows onto a second hard drive or clone your Windows operating system between disks of different sector sizes. And if that wasn't enough, WinToHDD offers a "hot clone" feature that enables you to clone Windows without restarting the clone source computer.
Another incredibly useful feature that WinToHDD offers is encrypting your Windows partition with BitLocker when installing or cloning Windows. Additionally, it's compatible with GPT/UEFI and lets you install any version of Windows 11/10/8/7/Vista & Windows Server (64 & 32 bits) from the same USB drive on both BIOS and UEFI computers.
WinToHDD system requirements include having at least Windows Vista/2008 and above (32/64-bit), an Intel Pentium processor, 1GB of RAM (2GB or more is recommended), 500MB of free disk space, and a 1024x768 graphic device (higher resolution is recommended).
Overall, WinToHDD is an excellent tool that makes it easy to manage and install Microsoft Windows operating systems without worrying about finding and managing installation disks or USB drives.
