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:

Set-ExecutionPolicy RemoteSigned

Since SharePoint Foundation 2010, patching SharePoint is a two-step process. The updated binaries are first installed and then PSCONFIG must be completed to update the SharePoint databases. 
Without completing PSCONFIG, you might experience unexpected SharePoint search failures and all backups may stop working on the affected server. 

You can run the following commands to determine if you need to complete the update process with PSCONFIG:

• Launch an elevated (Run as Administrator) SharePoint 2010 Management shell from start, All Programs, Microsoft SharePoint 2010 Products, SharePoint 2010 Management Shell.
• Once the shell opens, type the following command followed by enter:  
  (get-spserver $env:computername).NeedsUpgrade

In order to update the SharePoint databases, you must manually run the PSconfig utility. To run the utility:

1. Open an Administrative command prompt.  
2. Change directory to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN  
3. Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures

Change the OWA login from “Domain\UserName” to just “User Name”. This is useful when you have Single Domain Exchange environment.

Set logom format:

Set-OWAVirtualDirectory -Identity “owa (default web site)” -LogonFormat username -DefaultDomain “Your Domain Name”
