Graphics Tool

Graphics Tool is one of the essential components of Graphics Programming on Windows. During the installation of Visual Studio, the installer trys to automatically install Graphics Tool, but things are not always going well. In complicated network environment, such as in a company that has a strict firewall, or at the Chinese mainland which is blocked by the GFW, it is somewhat difficult to install Graphics Tools.

UseWUServer = 0

This method is suitable for those who have a WSUS server in their company, and have access to the Internet. I've encountered the situation while working for Tencent.

The clients are all configured to use a internal WSUS server, and sadl, although it seems that my client can acquire the latest updates, it cannot successfully install any Optional Features from the Settings, including the Graphics Tools.

So the way to solve it is to temporarily redirect our WSUS to the official M$ server and install what we need, and then restore the configuration.

• Open regedit, go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU, change the value of UseWUServer to 0, which disables the user-defined WSUS.
• Open Administrator cmd, call net stop wuauserv && net start wuauserv to restart windows update service.
• Install Graphics Tools from Settings -> Optional Features.
• reset UseWUServer to 0, restart the WU service.

Offline installer

The above method requires access to the M$ server, which is not the case when working in a completely offline environment. That's the case when my client is behind a firewall and only a small whitelist are allowed, and of course, Microsoft is not on the list.

I must point out M$ doesn't provide any available solution for this case. They boastfully stats that these Optional Features can be installed from a seperate Features On Demand ISO, but no one(perhaps excluding Windows developers) knows where to download the ISO. It seems the ISOs are only provided to some OEMs and not distributed publicly.

The only way I found is provided in this article

In a nutshell, When installing optional features, Windows Update downloads the installer, install it, and then automatically delete the installer. Therefore, we can quickly copy the installer out in a very short time window(about several seconds) between it is fully downloaded and it gets deleted. Luckily, we can try infinite times by uninstalling and reinstalling the feature.

After trying about 5 times, I finally captured an complete Graphics Tools installer. It is captured on a Windows 10 22H2 system, but I positively guess it is going to work across versions. Anyway, the method mentioned before is universal.

1. Download the Microsoft-OneCore-Graphics-Tools-Package~31bf3856ad364e35~amd64~~.cab to a favourite directory
2. At that directory, Open shell. Make sure your curret directory is same with the cab
3. Employ DISM to install it locally.

DISM /online /add-package /packagepath:Microsoft-OneCore-Graphics-Tools-Package~31bf3856ad364e35~amd64~~.cab`

Check the DebugLayer dlls are installed.
