Win7 32 bit does allow unsigned (by MS/WHQL) drivers, Win7 64 bit does not.

I've tested the latest qxl driver on a Win7 32 bit installation and it
installed properly, so I don't know what problem you are trying to point
at, I don't see any different behaviour between the qxl driver and the
virtio ones.

I'm running Windows 7 64 bit in fact; apparently there's no difference but QXL does not work. It seems Windows needs signed drivers only for VGA devices.

In the archive (drivers-details.tar.gz) are the driver details from the windows hardware manager; none is signed.
Attached is a screenshot (qxl-error.png) with the QXL driver exhibiting this odd behaviour (error 52); the other drivers work fine.

To make it work, I have to enable testsigning in the guest (test-signing.png):

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON

Might I ask you if you could create an additional screen in Spice Guest Tools to enable "Test Signing"? Like a tick mark or something like that.
Or maybe a simple notice that it has been enabled in Windows 7+.

I'm available for testing if you would like some help.

Thanks & regards,
