Windows 95 is a hybrid 16-bit/32-bit graphical operating system released by Microsoft Corporation in the year of 1995.
The "Start" button and "Taskbar" in the desktop computers was first started with the Windows operating system. It featured significant improvements to the graphical user interface (GUI) and its workings, including Desktop and Start Menu; support for 256-character mixed-case long filenames and preemptively-multitasked protected-mode 32-bit applications.
Windows 95 was the first operating system to introduce FAT32. It does not support older, 16-bit x86 processors; thus requiring an Intel 80386 (or compatible) processor running in protected mode.
