Windows 95 Chicago

Windows 95 offered, at long last, a well designed document-oriented desktop shell that worked much like the 1984 Macintosh Finder. It also included a new way of finding installed applications through a "Start" menu. And it included the same networking abilities as Windows for Workgroups.

It integrated the ability to run 32-bit applications similar to Windows NT or Windows 3.1 with Win32s. It no longer ran on a separate DOS product. But Windows 95 was not a pure "32-bit" OS: It was still based around the framework of Windows 3.x, 2.x and 1.x. It still ran on top of DOS, but bundled its own special "Windows 95" DOS (AKA MS-DOS 7). It could even still make use of DOS drivers. The 95 architecture was continued with Windows 98.

Most 95 CDs are NOT BOOTABLE. If a download does not include a boot floppy, please see Microsoft Windows Boot Disks

If the listed serials below do not work for a specific release, please see the Serials thread

You may also override the install type (no serial needed) by creating a file name MSBATCH.INF with the lines "[Setup]", and then "ProductType=1", placing that in the Win95 setup folder, and then running setup.

VMWare and VirtualBox can be problematic with Windows 9x. If you use those, you may need to disable various acceleration features first, or consider emulators like x86Box or PCem. Windows 95 has many issues on faster machines or VMs, requiring a number of patches in order to operate.

Release notes

"Chicago" was the code name for early development versions of Windows 95. These releases illustrate the step-by-step transition from Windows 3.11 to the final product, and the involved research.

Please be on the lookout for fake or questionable builds. Please see the thread about fake Chicago 56, 73(no letter), and 78 builds.

Installation instructions

We strongly recommend using the 86Box or PCEm emulators to try these builds out. VirtualBox is known to have serious issues.
