I tried to insert a mak key using sccm ODS command line slmgr.vbs -ipk <key> I get a failure The task sequence execution engine failed executing the action (Insert MAK key) in the group (Build the Reference Machine) with the error code 2147749907 Action output: ========= In the smsts.log i find Failed to run the action: Insert MAK key. Provider load failure (Error: 80041013; Source: WMI)

Where in the TS are you adding this task? Why are you adding a key to a reference build? Why not use the Windows settings task for this?Jason | http://myitforum.com/cs2/blogs/jsandys | Twitter @JasonSandys

I do it as one of the last steps. This works for Windows 7 but for 2008 R2 SP1 it gives this error. Why not do it in Windows settings task? Because that does not work with MAK keys. I get a windows setup faillure if I enter a MAK key there.
