A screenshot showing how Wine can be configured to mimic different versions of Windows, going as far back as Windows 2.0 in the 32-bit version (64-bit Wine supports only 64-bit versions of Windows) There is the utility winecfg that starts a graphical user interface with controls for adjusting basic options.

User-Mode Driver Framework (UMDF) is a device-driver development platform first introduced with Microsoft's Windows Vista operating system, and is also available for Windows XP. It facilitates the creation of drivers for certain classes of devices.
Available for Windows 7 to 11, or Windows Server from 2008 R2 to 2022; 32/64-bit x86 or 64-bit ARM. SoftPerfect RAM Disk can access memory available to Windows, i.e. on 32-bit systems it is limited to the same 4 GB as the 32-bit Windows itself, otherwise for physical memory beyond 4 GB it must be installed on 64-bit Windows.
Common device driver compatibility issues include: a 32-bit device driver is required for a 32-bit Windows operating system, and a 64-bit device driver is required for a 64-bit Windows operating system. 64-bit device drivers must be signed by Microsoft, because they run in kernel mode and have unrestricted access to the computer hardware. For ...
Starting with Windows XP, Microsoft began making 64-bit versions of Windows available; before this, there were only 32-bit versions of these operating systems. Programs and subsystems in user mode are limited in terms of what system resources they have access to, while the kernel mode has unrestricted access to the system memory and external ...
Windows Driver Frameworks (WDF, formerly Windows Driver Foundation), is a set of Microsoft tools and libraries that aid in the creation of device drivers for Windows 2000 and later versions of Windows. It complements Windows Driver Model, abstracting away much of the boilerplate complexity in writing Windows drivers.
Many 16-bit Windows legacy programs can run without changes on newer 32-bit editions of Windows. The reason designers made this possible was to allow software developers time to remedy their software during the industry transition from Windows 3.1 to Windows 95 and later, without restricting the ability for the operating system to be upgraded to a current version before all programs used by a ...
The 64-bit Windows Native Mode [39] driver environment runs atop 64-bit NTDLL.DLL, which cannot call 32-bit Win32 subsystem code (often devices whose actual hardware function is emulated in user mode software, like Winprinters). Because 64-bit drivers for most devices were unavailable until early 2007 (Vista x64), using a 64-bit version of ...
