What is the Windows Driver Model?
The Windows Driver Model is an older device-driver framework. Also known as WDM and once called the Win32 Driver Model, it was introduced with Windows 98. It replaced the Windows NT Driver Model and VxD, which was used on Windows 95 and Windows 3.1.
The WDM was an advancement over past frameworks as standardized requirements and, in some ways, reduced the amount of code that was needed. If drivers follow the WDM framework, they are, at least in theory, binary and source compatible across Windows 98, Windows Me, Windows 2000, Windows XP, Windows 2003 and, for backwards compatibility, Windows Vista. The drivers are set up to be forward compatible so that a WDM driver can run on a version of Windows newer than what it as written for. However, there are a number of limitations. On a newer version of Windows, the drivers will not have all of the latest features and your hardware devices might not function at their best. That is why it is important to try to keep your device drivers up to date.

While a marked improvement over its predecessors, the Windows Driver Model has been criticized by developers for a number of reasons. Some of the biggest beefs are with its occasionally poor interactions with Plug-and-play hardware (where bugs in driver code make it hard for PCs to go to sleep or wake up) and in the number of lines of support code that are required.
These issues helped bring about the development of the Windows Driver Foundation, which includes the Kernel-Mode Driver Framework (KMDF) and the User Mode Driver Framework (UMDF). Newly updated drivers will be of this more efficient and reliable variety.
Congratulations on a brilliant product that fulfils a serious need and does it with style. I was thinking of getting a new PC as my current one was taking anything up to an hour to stabilise itself. DriverCure has reduced that stabilisation time to three or four minutes and let me highlight other issues that I expect to reduce it further when solved.
I have been using RegCure for a while and have been very impressed by it – but DriverCure is something else entirely. It does take a little nerve and patience, particularly when an install that needs a restart kicks off others during the shutdown process, but it has stressed to me the importance of keeping drivers up to date.
I'm sure there have been other products that help do this, but the ease of use of this software takes some beating, especially for the person who has some knowledge but is a "non-geek" in technical matters.
It would be useful if the drivers could be categorised into those that can be installed in sequence and those which need a restart – or if there was perhaps a tutorial available on how to work this out for yourself. Some of the components I upgraded, particularly the video drivers, were a little scary, but my experience with RegCure told me that this software was about as safe as I was likely to get. A few deep breaths before starting – and safe it has proved to be. Even the wife has stopped pointing out how much slower the machine is compared with her (networked) one at work.
You seem to have a knack of demystifiying the nastier parts of Windows, and my experience suggests this was long overdue. I hope the release party was a good one – you guys deserve it!
