Windows 95 OSR 1

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.

Windows 95 OSR 1, ("A" version) was a minor update of various core files. It was available as a downloadable update and as a full OEM CD.
