The Windows Management Framework 3.0 (KB2506146 for Windows 2008 SP2 and KB2506143 for Windows Server 2008 R2) has been recently offered as an optional update on Microsoft update distribution clients such as Windows Server Update Services, and Windows Automatic Update.

The above screen-shot is from Windows Small Business Server 2011 Standard. On a Windows Small Business Server 2008 Standard, you should look for “kb2506146”.
You could also run the command Get-Host on a PowerShell prompt to find the version of Windows PowerShell, as:
PS C:\Users\admin> get-host
Name : ConsoleHost
Version : 3.0
InstanceId : e66e1400-9f45-4205-8151-9ed07a1823ba
UI : System.Management.Automation.Internal.Host.InternalHostUserInterface
CurrentCulture : en-US
CurrentUICulture : en-US
PrivateData : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy
IsRunspacePushed : False
Runspace : System.Management.Automation.Runspaces.LocalRunspace
It will show the PowerShell version as 3.0, which implies that the PowerShell has been updated to the newer version.
In such scenarios we suggest you to uninstall the Update.
Our guidance at this time is that Windows Management Framework 3.0 should not be deployed on a server running Windows Small Business Server 2008 Standard or Windows Small Business Server 2011 Std.
