It is almost comical that when searching for a video about Windows Drivers' Development so far, I was only getting results from 10 years ago that have completely given up on that specific matter so the information on these outdated videos is also minimal, and now, out of nowhere, I bumped into this video on my home page. I'd really love to see more guides concerning drivers' development. That was incredible.
Pavel Yosifovich is another good source. Dont know about his videos, but he's written good low level programming type books, such as device driver dev and theyre current.
Actually i kinda go back to win32api because i find Qt apps so damn slow in startup. Having a high perf pc and then those startup time make me think we go backwards. And i hate win32api. but it's probably instant compatible running on linux aswell with WINE emulation.
Video starts "Before you start writing a driver" Wait.. You skipped 6 steps. "Hello", "Subscribe", "Like", "Sponsor", "Basic shit you should know before even clicking the video", and "Thank you". Overall. Nice, short, and concise video. More of this please!
I thought "There's no way a sub 8 minute video is going to be enough to be informative for a topic like this." I was completely wrong. This was well paced, straight forward, and better than I could have imagined. This will be the go-to video I send to people who want to start with kernel mode dev but don't understand quite where to get started. Also: What shell replacement are you using, It looks swell!
Thanks! :) I use a port of Suckless dwm for Windows called dwm-win32, it actually sits on top of the shell and does not replace it but rather it works by managing the existing windows and listening to newly created ones
I love Your work. Very helpful. You proved us that creating a driver is not a rocket science. Now some humorous stuff. When I saw the driver not stopping from executing, I expected that You'll like a true programmer make fun of it by saying: "OMG, how is this thing stopping?"
Even though I learned about drivers back in Uni. It was all theory. your 7-minute long video was the missing piece. Like your video style, not asking for [like , share, comment] just straight to the point with no pauses. Appreciate your hard work. p.s: liked , shared, subed ✅
It amazes me how someone can be both a CS geek and cute at the same time I've always been interested in drivers development, but despite having both hardware/electronics and kernel knowledge, I had no idea of where to start for drivers, ESPECIALLY on Windows. Thanks!
You explain very well....the delivery is rare ....many videos I've watched...it's rare to get explanations that actually explain things if that makes sense... thank you ♌🙌🏽💗
I've been wanting to know windows driver dev for years and suddenly you make this video! Thank you. Would you be able to do more tutorials on windows drivers? For example, what about a driver for a virtual floppy disc or something? I'd love to see that.
Wow, this was an amazing video! so clear and so informative without skipping any steps (like sadly so many do) that are "obvious" to people who this every day
Nir, thanks, i don't understand anything about MicroSoft Windows, running Linux since 1994 as wel as some UNICES. Your video however is the first interesting instruction on MicroSoft development i have ever seen. Main interesting thing is that you actualy show whats happening iso obfuscating the whole process using an IDE.
The couple cringe comments bashing Vim or C is laughable and makes one question if they even know programming. Great video, most have sought profit by means of their 20 minute diatribes, inefficiently transmitting that thing called knowledge. This is a pleasant contrast.
Really fantastic how the algorithm shows something I didn’t think I wanted to learn but now I do. Why though you needed the two voided parameters but wasn’t used on call with null unless I missed something. תודה
That is just to follow the entry point signature according to the docs which specifies that the driver entry gets two parameters, I did not used the information passed into these parameters so I just ignored them. בכיף 🙂
are you using a tiling window manager within windows? or do you just have multiple instances of a vm on different linux workspeces? if so, what tiling window manager are you using? I tried komorebi a few years back but it was pretty early in development back then.
that looks like i3 and it's a nice wm for linux. seeing it on windows is kinda cursed but it got me curious too. anyways maybe give i3 a try, it's pretty easy to setup and configure
Interesting, after 10 years of linux kernel programming, I never knew that windows also has something akin to dmesg, I also love how short and to the point this was. Kol hakavod.
Toda! It's somewhat similar to dmesg but also different since dmesg shows you the kernel log buffer and the program dbgview just connects as a debugger to the user mode programs/kernel and shows you debug prints (although it does have a feature to log boot)
I've been developing kernelmode driver for anti-cheat system, used assembly on x86 and ObRegisterCallbacks on x64. This is one of the examples. Another example is a device driver as you can access everything from kernel, you can for example ask PCI device directly.
If you just want to play around and learn I would suggest using VirtualBox or VMware or something similar. Then you don't have to restart. Also if you brick your computer like infinite boot loop or something then with VM you just restore previous snapshot and you are ready to go again.
It won't show up in the services application since it is technically not a service but a kernel driver (I ran sc with type= kernel), SC supports also creating and loading drivers and calls them also "services" but you can see it is a driver by looking at the type (with sc query for example) and seeing that it says "KERNEL_DRIVER".
How did you get into driver developement ? Do you have a software engineering background or CS education ? Or more like an embedded systems background and a CE educaction ?
I don't quite understand what a driver does. What is the difference from a "normal" program? And isn't a driver a specific program that a hardware uses to communivate with the OS? If so, the driver you created doesn't have any hardaware attached to it. If you could explain to me... thanks!
Can you make video of getting your driver signed so you could run it normally? It's something that we all have to do at some point anyways. MS official tutorial can be big and scary at the beginning. It's not clear if it costs money or if if it's possible for free also.
Is there any way to install custom certificates or anything so that we can sign our own drivers? Disabling driver signature verification permanently is becoming very difficult on modern Windows versions if I remember correctly. It used to be easier.
Nice Would love to see a more detail video like how to comunicate with a driver from ur user program Suppose u are making a device driver, so how would u get data in and out of it with ur user program so u could comunicate with a device on the other side of a driver?
Very nice. Things I want to know: - Is the "cl" compiler "Clang" or something else ? - What happens when you crash a driver ? Do you know the procedure to handle that safely or is it a guaranteed blue screen ?
- "cl" is the Visual Studio compiler - unless you tell it to compile only, it also calls the linker after it finishes compiling (in the video I passed to cl flags for the compiler and for the linker) - You can handle exceptions in the driver safely - more information here: learn.microsoft.com/en-us/windows-hardware/drivers/kernel/handling-exceptions
I don't seem to be seeing the "km" folder. I'm wondering if there was something I had to do beforehand to gain access to that folder. I see a "um" folder, presumably "user mode". EDIT: followed the guide for downloading the SDK and the WDK and we're good now. I guess what was already installed in the directory only included the user mode directory "um".
Nasty, dude. Rock! You make the NirSoft stuff? Just wondering, with the coincidence in names is all. I like those tools a lot myself and use them since forever. Same with Russinovich's stuff.
Thanks :) .inf and .sys serve a different purpose, the sys file is the actual binary of the driver while inf files are textual config files that tell Windows how to install software/drivers
I'm getting error startservice failed 577, "Windows cannot verify the digital signature for this file". I have checked that I have done the step where you disabled the Windows driver signature enforcement; am I missing a step?
Access and manipulate kernel data structures normally not available in userland, implement file system filters, hook system calls, etc. The term "driver" in Windows tends to more generically refer to kernel modules (in Linux terminology), rather than just stuff for "driving" actual hardware. That said, you do also have some "user-mode drivers" that *are* for driving hardware, and don't run in kernel mode ¯\_(ツ)_/¯
C++ isn't supported in kernel driver development as it uses memory in ways kernel mode drivers can't support due to the nature of memory management in the kernel.
@paradoxicalcat7173 literally usermode functions such as readprocessmemory is streamed from kernel... what you said is basically "i cant read this book, because its in French, and translations are impossible"
Hello, I'm from Brazil, my English is at translator level. I started studying the x86 architecture, I can now create some codes. Could you guide me? I have an old notebook to do the tests. It uses several VIA components. My question, how do I get the codes for hardware control and stuff? Like, the bios has its interrupts is it a super I/O, video card? Everything is very confusing, this part involving peripherals.
Thank you! I had to modernize a driver for Win11 to use a 12+ year old printer. It's an amazing Canon from before the ink stuff started getting bananas. I spend $20/year on ink. The only problem I have is that Canon didn't want to modernize the driver! I've only developed for private companies. I know how they lock down IP and have heard that camera companies have gotten super greedy as well. Is it legal for me to release what I have for a win11 driver so others can enjoy it? Bound by US law here, so a bit nervous navigating this IP minefield lol I'm not hiring an attorney for my first FOSSy aspirations 😅
Drivers enable you to operate in kernel level and call kernel functions (for example the function I use in the video DbgPrint is implemented in the kernel) and are useful for a variety of reasons for example adding support for new devices, implementing a file system or just for fun and learning :)
@@nirlichtman cool touchscreen drivers, mouse pad drivers, keyboard drivers. Is it true that without drivers the hardware wouldn't be able to interact with humans?
4:30 so back in 2020 i think, I tried vjoy driver installation but failed because it wasnt signed. I enabled test mode and it still didnt work. Now vjoy is signed by someone who loves paying hundreds of dollars a year but i still dont get how test mode didnt work at all…

If you just want to play around and learn I would suggest using VirtualBox or VMware or something similar. Then you don't have to restart. Also if you brick your computer like infinite boot loop or something then with VM you just restore previous snapshot and you are ready to go again.
The cmd prompt to compile this alone make me cry. The extra steps to make it work put me in fetal position.
This is great thank you. I never knew how to create services like that. Would that service also show up in Windows services?
It won't show up in the services application since it is technically not a service but a kernel driver (I ran sc with type= kernel), SC supports also creating and loading drivers and calls them also "services" but you can see it is a driver by looking at the type (with sc query for example) and seeing that it says "KERNEL_DRIVER".
Great video. I would just add that you should always wear your seatbelt when writing a driver. Safety first.
How did you get into driver developement ?
Do you have a software engineering background or CS education ? Or more like an embedded systems background and a CE educaction ?
Awesome, nice and simple. 👍
Nice one 👍 is that working with hive and hardware abstraction layer ?
It’s better to debug your driver inside a VM to avoid having to restart your PC every time you get a BSOD
The first time I wrote a Windows driver I didn't BSOD the machine once. Driver dev isn't for you if you can't handle memory.
no intro, no curve ball, just straight nerd-ery
I don't quite understand what a driver does. What is the difference from a "normal" program? And isn't a driver a specific program that a hardware uses to communivate with the OS? If so, the driver you created doesn't have any hardaware attached to it. If you could explain to me... thanks!
