Websites like WinWorldPC or the Internet Archive are the primary hubs for these files. When searching, you will often find two types of downloads:

Once you have downloaded your ISO, the most common way to run it is through a virtual machine. This prevents the need for 30-year-old hardware. If you are using VirtualBox, you should create a new VM and select Windows 3.1 as the version. You will need to allocate very little RAM—usually 16MB to 64MB is more than enough. Since Windows 3
Windows 3.1 remains a legendary piece of software history, representing the moment graphical computing truly entered the mainstream.

From there, you typically navigate to the Windows directory and type "win" to launch the interface. If it is an installation ISO, you will run "setup.exe" to begin the process of copying files to your virtual hard drive. Drivers and Modern Compatibility
