Hello,

I would like to develop a driver. This driver emulates a sound card and is
based on the MS Virtual Audio Device (Simple) of the WinDDK.

Everything is working with WinXP x86, but when I try to install it on Win7
x64, it is disabled, because Win7 requires a driver to be digitally signed.

I cannot afford to buy a certificate. Is there any other way for Endusers to
install my driver on Win7?

Regards,
Max

The only option is to have the end user hit F8 at boot and select the
ignore digital signing requirement. This is not something most users are
willing to do.

So there is no chance to develop a freeware driver for windows?

Sure you can develop such a driver. You just have to be willing to pay
for the certificate or find a company that will be willing to sign your
driver. You can also put out the source, and let people use it as they
wish including signing the code.

It is a pain to have to sign it, but there is a justified need to know
where the code being loaded into the kernel is coming from, and be able to
block things that are shipping malware.

Well, is there any company who looks through someone's code and pay for the
signing?
