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 ...
WDM is the driver model used since the advent of Windows 98, whereas KMDF is the driver framework Microsoft advocates and uses for Windows 2000 and beyond. In general, since more features like power management and plug and play are handled by the KMDF framework, a KMDF driver is less complicated and has less code than an equivalent WDM driver.
User-Mode Driver Framework v2, for writing user-mode drivers with syntactic parity to KMDF WDF also includes a set of static verification tools for use by driver writers. These tools examine driver code for common errors and/or simulate the code of a driver in order to identify problems that are both difficult to detect and difficult to test for.
In this guide, we'll show you the proper steps to upgrade from the 32-bit to the 64-bit version of Windows 10 without purchasing a new license. ... Windows 10 64-bit download. Click the Next button.
Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
I/O request packets (IRPs) are kernel mode structures that are used by Windows Driver Model (WDM) and Windows NT device drivers to communicate with each other and with the operating system. They are data structures that describe I/O requests, and can be equally well thought of as "I/O request descriptors" or similar.

The upper part is accessible only from kernel mode, and with some exceptions, is instantiated just once, system-wide. ntoskrnl.exe is mapped into this region, as are several other kernel mode components. This region also contains data used by kernel mode code, such as the kernel mode heaps and the file system cache.
