UPDATE (10/31/2008): We just released the Windows Server 2008/SP1 WDK, which includes the coinstallers. This WDK is versioned as 6001.18002 and can be found here. Apart from the coinstallers, this WDK also has some additional changes, which are described here. The rest of the post has instructions on how to download the 6001.18001 WDK (i.e. the previous version of the WDK). We strongly suggest that you download version 6001.18002. If you do so, then you don’t need to download the coinstallers from the seperate msi.
It still puzzles me that we continue to get emails from people, who cannot find either the latest WDK or the WDF 1.7 coinstallers.
So, just for completeness the steps are:
- Go to https://connect.microsoft.com/Downloads/Downloads.aspx?SiteID=148 (if you have problems signing in using Firefox, then try Internet Explorer)
- Login with your Microsoft Passport or your Windows Live ID. If you don’t have one, then you need to create one for free.
- After you login, you’ll see a page which has a link for “WDK for Server 2008” (this is the WDK versioned as 6001.18001 and IT DOES NOT HAVE THE WDF 1.7 coinstallers) and a link for “WDF (KMDF and UMDF) 1_7” (the WDF 1.7 coinstallers). You can download just either the coinstallers or both packages, depending on whether you need just to use the redistributable or if you need to develop new drivers.
The coinstallers have been there since 18th April 2008.
