PowerShell - Set-Culture doesn't seem to change anything

Question

I have a Cloud Service Web Role that I need to run some PowerShell on to ensure the server is always setup in the right culture: en-AU.

The reason for this is that Microsoft could, at anytime, reset the culture values.

When I run:

Get-Culture

I get:

1033 en-US English (United States)

So then I run:

Set-Culture en-AU

But I still get:

1033 en-US English (United States)

I have tried many things but nothing seems to really change the culture.

Any help would be great.

Like petseral said in a comment above:

Changing user locale does not affect already started PowerShell instances.
You have to start new PowerShell process.

Accepted Answer

The root cause is because you are not running the PowerShell with Administrator privilege.

Set-Culture needs Administrator privilege to be set on the system.

Just run your PowerShell in Administrator mode and your culture will be set to the new one as below:

Hope this helps!
