Windows 95

Windows 95 Screenshot The new Windows operating system with the internal version 4.0 is the successor of Windows 3.11 and brings a completely new design of the interface and of the kernel with it. 32-bit applications are supported fully, DOS applications can also virtually be used now in a DOS box, furthermore 16-bits of programs are supported. Windows 95 to ME still needs DOS for the loading up program and for the DOS box. New hardware is comfortably recognized by plug and play, the memory management was developed further considerably.

Important part of Windows 95 is the Registry now, which is responsible for the system behaviour like file assoziation, program parameter, driver software, system configuration and others. The Registry consists of the files system.dat and user.dat, these are located in the Windows directory. The files system.ini and win.ini are less important but are necessary for the system start furthermore. For user profiles one user.dat is placed in each user directory and loaded upon login of the user for the individual user settings.

DOS driver software are no longer necessary in compare to Windows 3.x by now, the driver software model was changed and the hardware is used through virtual device drivers (*.VxD) directly under Windows.
