Using the Set-ExecutionPolicy Cmdlet

Date: July 15, 2013 Author: Sefer Simsek Comments: Leave a reply

Changing the Windows PowerShell Script Execution Policy
The Set-ExecutionPolicy cmdlet enables you to determine which Windows PowerShell scripts (if any) will be allowed to run on your computer. Windows PowerShell has four different execution policies:

  • Restricted – No scripts can be run. Windows PowerShell can be used only in interactive mode.
  • AllSigned – Only scripts signed by a trusted publisher can be run.
  • RemoteSigned – Downloaded scripts must be signed by a trusted publisher before they can be run.
  • Unrestricted – No restrictions; all Windows PowerShell scripts can be run.

To assign a particular policy simply call Set-ExecutionPolicy followed by the appropriate policy name. For example, this command sets the execution policy to RemoteSigned:

Get-ExecutionPolicy
Set-ExecutionPolicy RemoteSigned

How to install .NET Framework 3.5 on Windows Server 2012

Date: April 1, 2013 Author: Sefer Simsek Comments: Leave a reply

Apparently, there’s a bug in Windows Server 2012 when trying to add the .NET Framework 3.5 from Server Manager. In order to get it to work, I had to enable the feature via the Command Prompt.

This is the command that I had to type:

dism /online /enable-feature /featurename:NetFX3 /all /Source:d:\sources\sxs /LimitAccess

Note-1: Source should be the Windows installation disc. In my case, this was located on D:
Note-2: CMD or powershell must be administrator rights.
