Windows 95

Windows 95 (codenamed Chicago) is a consumer version of Microsoft Windows released by Microsoft in 1995. It is the first major release in the Windows 9x operating system line, and was designed to be the successor of Windows 3.1. It would be replaced by Windows 98, and Microsoft ended support for Windows 95 on 31 December 2001. It improved upon 16-bit Windows by introducing a hybrid 16/32-bit kernel and eliminating the need for an existing installation of MS-DOS, making it a standalone operating system (running alongside MS-DOS). Microsoft focused on improving the usability of Windows with technologies such as Plug-and-Play, long file names (VFAT), the Start Menu, an updated Desktop, Internet Explorer, Mail, built-in networking, and virtual device drivers. Many of the paradigms introduced with Windows 95 remain in use today.

It was a revolutionary update for Windows, and also the first concerted effort by Microsoft to listen to consumers. Although it was still built upon the solid, if outdated, foundations of MS-DOS, the average user never saw the MS-DOS prompt unless they wanted to. Windows NT was too intensive for most computers of the time, and it was not until after the release of Windows 95 that Win32 applications were widely used and supported.

This is the last version of Windows to be available on 5.25-inch floppy disks, specifically the original release. At this point, Microsoft no longer offered the floppy release of Windows for OEMs, as the CD release became the more widespread one.

Product Team credits Easter egg
There is a hidden Easter egg, which can be accessed by creating a new folder and renaming it to each of the following names in order:

 * we proudly present for your viewing pleasure
 * The Microsoft Windows 95 Product Team!

Opening the folder after the last rename opens an Explorer window, although the file list area is replaced with an animation of names of people involved in the development of Windows 95 on a blue cloudy background with  playing in the background. This MIDI file is also subsequently added to the  directory upon launching the Easter egg.

The text is located in the library's resource  and XORed with   as an obfuscation measure. Likewise, the Easter egg folder names are stored in the  section of   as custom hashes of the old folder name concatenated with the new folder name.

This Easter egg is also present in Windows NT 4.0, with references to "95" being replaced with "NT".
