Hi everyone! I am trying to develop a new driver based on minispy code. I have successfully install minispy on my windows 11 (Surface computer) But i am trying to install the driver also on a window 10 (HP) and a Windows 11 dev (VM created with hyper-V) but it doesn't work... I have found the base code in this link : https://github.com/microsoft/windows-driver-samples/tree/main/filesys/miniFilter/minispy
after that i build it in Realease mode with visual studio 22 17.1.7 and i tried to install it by right-clicking on the minispy.inf and on install.
After this part I see minispy when i am running the command
driverquery
in my computers and VM, but when i am trying to start the service by running in an administrator command prompt
net start minispy
I get this result on my VM and my windows 10 computer (translate form french) :
error system 127
the procedure is unfindable
I don't really know what are the differences and I am feeling kind of lost here... If someone can help me i would be very happy!

Hi @bertrand leo ,
Welcome to Microsoft Q&A forum.
I just want to confirm if this issue is related to Visual Studio. May I ask whether VS prompted any error when you built this sample project? If it was built successfully I think you may also need to ask this question on GitHub to confirm whether some components are needed to use it.

I compiled it in VS2022 and even created a cat file, but an error occurs when I try to install it.
The meaning of the error is "There was a problem adding the driver to the repository"
And above image is spec. of Windows.
And attached file is minispy.inf actually.
Who can tell me what is wrong?
Thanks in advance.

我也遇到了同样的问题。我在vs2022没有找到minifilter模板，我使用了vs2019生成minifilter，按照微软的inf要求修改inf文件后，可以提交微软签名成功，但是不能加载。错误是127。
