Windows 7: Using an unsigned driver in Win 7 x64. Can I sign the driver myself?

Using an unsigned driver in Win 7 x64. Can I sign the driver myself?

I have a program that has a driver for Windows 7 x64. For various reasons this driver is unsigned. I know the manufacturer and it's safe. I know that I can put computers into test mode to load the unsigned driver but I'm concerned that mode allows any other unsigned driver to load.

Is there a way to allow only one specific unsigned driver to load in 64-bit windows? For example can I sign the driver myself, add that certificate to the master certificate store, and then use that driver without having to enable test mode? Or does it not work like that?

Any ideas or explanations welcome, Thanks!

The last time I had an "unsigned driver" message, I had an "Install anyway" button. Do you ever get one of those?

Some unsigned drivers work but most of them don't (I have Realtek AC'97 unsigned driver working flawlessly).

I have no idea if doing this is legal or not, so I request mods to check and delete my post if required.

I found this page, see if this helps: How to Install & use unsigned drivers in Windows Vista/7 x64 - TechSpot Forums

Unsigned or non-WHQL? Big difference between the two. Non-WHQL can show as unsigned, but can be installed anyway after the "warning" message like TwoCables mentioned. This is common with just about any beta driver or a driver that was WHQL and has had its INF modified in any way.

Unsigned is a driver that doesn't have the appropriate .cat/signature file in it. And no you can not sign it yourself, unless you want to pay Microsoft to have it tested and the certificate issued (last I saw it was $500 or so to do).

Damn that's what I thought. It's unsigned. I thought maybe there was a way to inject my certificate into the store and then sign with that certificate so that I could leave integrity checks enabled and test signing disabled.
