Powershell: some modules unavailable when called via CreateProcess()

Under what conditions do some PowerShell modules become unavailable?

When I create a process with CreateProcess() and the command line

powershell -Command "Get-Module -ListAvailable"

I don't get all the modules I get when executing the same statement from a command prompt.

Are there any fields I have to set inside the STARTUPINFO or PROCESS_INFOR开发者_Python百科MATION structs?

Some modules are not available in the 32 bit version of PowerShell. On Windows Server 2008 R2 with PowerShell v1.0 these are:

• ADRMS
• AppLocker
• BestPractices
• ServerManager

The set of modules available is controlled by the PSModulePath environment variable. It's possible that the two processes in question here have 2 different values for PSModulePath and hence you see 2 different sets of modules.

Can you check the value in both cases and see if it's different?
