Vista - Set-ExecutionPolicy in RunOnce doesn't work

I'm trying to deploy PowerShell using SMS and I need to set the
ExecutionPolicy to Unrestricted. Occasionally, the installation
requires a restart so I can't just run Set-ExecutionPolicy
Unrestricted in the package.

I was planning to use RunOnce but it doesn't work. Here are some of
the command lines I've tried:

%windir%\system32\windowspowershell\v1.0\powershell.exe Set-
ExecutionPolicy Unrestricted

I've also tried:

%windir%\system32\windowspowershell\v1.0\powershell.exe Set-
ExecutionPolicy Unrestricted > C:\Logs\ps.txt

the file isn't created.

I've also tried -noninteractive with the same result. Does anyone
know why it doesn't work and how to get it to work?

Hi

Try one of the following:

1. PowerShell -Command {Set-ExecutionPolicy Unrestricted}
2. PowerShell -Command "& {Set-ExecutionPolicy Unrestricted}"

I suggest you set it with 'remoteSigned', it is more secure.


You can also set the value through the registry, search for the value 'ExecutionPolicy'
under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell


Or even use a GPO Administrative Templates for Windows PowerShell:

Thanks very much for the suggestions - I'm playing with the registry
setting at the mo and it's looking good.

That's the technique that I use. I use a WSH script with WMI's registry
provider; it makes it fairly simple to run through a specific list of
machines and directly inspect and/or set the values.

There are two special situations you should be aware of with the path shown,
moving forward, however.

(1) There are distinct keys for the 32 and 64-bit versions of PowerShell if
you run 64-bit Windows. The path Shay mentioned is for the OS-native-bit
path, so if you want to make sure the 32-bit PowerShell is adjusted on
64-bit Windows, you need to check
HKLM\Software\Wow6432Node\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell

(2) Moving forward, there will eventually be situations where there are
multiple PowerShell version numbers (not just the subpath 1) and multiple
product identifiers (not just Microsoft.PowerShell). This isn't likely to be
a significant immediate problem, but sometime in the next few years for
blanket inspection/modification on a general OS, you'll need to try
enumerating subkeys under both

HKLM\Software\Microsoft\PowerShell
and
HKLM\Software\Wow6432Node\Microsoft\PowerShell

and for each version number subkey under each of those, you will need to
enumerate product keys under ShellIds. Essentially all valid paths are of
the form:

HKLM\Software\[Wow6432Node\]Microsoft\PowerShell\<version#>\ShellIds\<productname>

Where [Wow6432Node\] is optional.
