Installing Test-Signed Driver Packages
Starting with Windows Vista, a test-signed driver package should install and load without user interaction if the following conditions are true:
The driver package complies with the generic requirements of Windows Vista and later versions of Windows.
The driver package is signed and the signature is verified, as described in Test-Signing Driver Packages.
The driver package is not altered after it is signed.
The test certificates that were used to sign the driver package are installed correctly on the test computer, as described in Installing a Test Certificate on a Test Computer.
If a non-PnP driver has a signed catalog file instead of an embedded signature, the installation application that installs the driver has installed the catalog file in the system catalog root directory, as described in Installing a Test-Signed Catalog File for a Non-PnP Driver.
Test-signing is enabled on the test computer. For more information, see the TESTSIGNING Boot Configuration Option.
