Older software even games can come with security flaws that could put your PC at risk. If Windows can find alternative settings, it will attempt to apply them and allow you to test them. If you have a copy of Windows 95 gathering dust in your attic or basement, dust it off and make an ISO file from the installation media.
GOG is a gaming marketplace that allows you to buy older games without resorting to piracy, where suspicious files from dodgy-looking websites can often bring nasty surprises.

INI, load the virtual device drivers, and then turn off any running copies of EMM and switch into protected mode. These VxDs allow Windows 9x to interact with hardware resources directly, as providing low-level functionalities such as bit disk access and memory management. All future file system operations would get routed to the bit file system manager.
In Windows Me , win. VXD from IO. When a program issued, say, an int 21h call to access MS-DOS, the call would go first to the bit file system manager, who would attempt to detect this sort of patching. If it detects that the program has tried to hook into DOS, it would jump back into the bit code to let the hook run. SYS, the job of which was which was to hook MS-DOS first before the other drivers and programs got a chance; and jump from bit code back into bit code, when the DOS program had finished, to let the bit file system manager continue its work.
Any bit drivers and programs would patch or hook what they thought was the real MS-DOS, but which was in reality just a decoy. If the bit file system manager detected that somebody bought the decoy, it told the decoy to quack. Thus, the security model is much less effective than the one in Windows NT. FAT systems have very limited security; every user that has access to a FAT drive also has access to all files on that drive.
Most of the feature set and compatibility of the Windows 9x line of operating systems was merged with Windows NT with the release of Windows XP, which was the successor to both Windows and Windows Me. As a bit operating system, virtual memory space is 4 GiB, divided fixed, lower 2 GiB for applications and upper 2 GiB for kernel per process.
Like Windows NT, Windows 9x stores user-specific and configuration-specific settings in a large information database called the Windows registry. Hardware-specific settings are also stored in the registry, and many device drivers use the registry to load configuration data.
INI and other files with an. INI extension to maintain configuration settings. As Windows became more complex and incorporated more features,. Backwards-compatibility with. Although Microsoft discourages using INI files in favor of Registry entries, a large number of applications particularly bit Windows-based applications still use INI files.
Windows 9x supports INI files solely for compatibility with those applications and related tools such as setup programs. SYS files also still exist for compatibility with real-mode system components and to allow users to change certain default system settings such as the PATH environment variable.
The registry consists of two files, User. In Windows Me, Classes. Its primarily responsibility is to create, run, monitor and terminate virtual machines. The VMM provides services that manage memory, processes, interrupts, and protection faults. The VMM works with virtual devices, bit protected-mode DLLs, to allow the virtual devices to intercept interrupts and faults to control the access that an application has to hardware devices and installed software.
Both the VMM and virtual device drivers run in a single, bit, flat model address space at privilege level 0 also called ring 0. The VMM provides multi-threaded, preemptive multitasking. It runs multiple applications simultaneously by sharing CPU central processing unit time between the threads in which the applications and virtual machines run.
