I have found through experimentation that timestamps made with /tr are not recognized on Windows Vista, for either executables or drivers. If you open the properties for your signature in Windows Vista, you will see that there is no timestamp listed. I suspect that Windows XP behaves the same way, but I have not tested it, but someone else has. Don’t use spaces in the INF file name.This is an additional requirement for driver package installation that was reported by Jimmy Kaz. I have not tested it myself, but he says that the driver package will appear to be unsigned in Windows 7 if the INF file has spaces in the name.

If your driver only uses WinUSB or usbser.sys, all you need to worry about is getting your driver package installed, as described in the Installing a driver package section. The kernel modules you are using have already been signed by Microsoft and you will have no trouble getting them loaded into the kernel after the driver package is installed.

Understanding Convenient Programs Of Driver Updater

The friendly driver installation prompt for signed driver packages in Windows 8 looks pretty much the same as it did in Windows Vista and 7. Since the number of people using Windows Vista is pretty small these days, you can simply put a note in your documentation that tells Windows Vista users to make sure they have that update installed. If your certificate uses SHA-2 or has SHA-2 certificates in its chain of trust, then you should be aware of KB , an update for Windows Vista SP2 distributed through Windows Update. On versions of Windows Vista without this update, when the end user double-clicks on a downloaded executable with a signature whose chain of trust uses SHA-2, nothing happens!

  • Almost none of the addons work which for me was the main attraction.
  • While you might still have to make small tweaks here and there, the initial setup is most of the work.
  • Contrary to its claim as a fast browser it is slower than even Opera Potable.
  • Now you don’t have to wonder what to do after installing Windows 10.

The EV certificate is more expensive and probably more of a hassle, but it is required by Microsoft if you are going to sign kernel-mode https://www.rocketdrivers.com/devices/firewire drivers and you want those drivers to generally work on Windows 10. Also, an EV certificate will give you "immediate reputation with Microsoft SmartScreen", making it less likely for users to see random errors when they download signed executables from you. If your certificate uses SHA-2 or has SHA-2 certificates in its chain of trust, then you will not be able to use it to get kernel modules loaded into the Windows Vista 64-bit kernel. I tried to make this work on multiple occasions but I was never able to. If you really need to make new kernel-mode drivers for Windows Vista 64-bit, you might try instructing your users on how to disable driver signature enforcement.

SHA-1 A signature must be present and it must not use SHA-2 in any way, only SHA-1. This applies to the signature of the file itself and the signatures that secure the chain of trust to your certificate. This probably also applies to the timestamp and its chain of trust. Note that Microsoft is retiring SHA-1 and will eventually distrust it throughout Windows in all contexts, so sticking to SHA-1 will not be a long term solution.

Choosing Trouble-Free Plans For Driver Updater

A good option is the code signing certificate offered by Globalsign. You will have to choose whether to get an Extended Validation certificate or a normal certificate.
