Enable PowerShell commandlets for SharePoint 2013 in PowerShell ISE

Open the PowerShell ISE and create a profile by running the following code:

if (!(test-path $profile.AllUsersAllHosts))
{
     new-item -type file -path $profile.AllUsersAllHosts-force
}

Open the newly created profile with the following command:

psEdit $profile.AllUsersAllHosts

The profile will be open in the PowerShell ISE. Add the following code to the profile:
(If the profile for some reason doesn't open then you can get it here:
C:\Windows\System32\WindowsPowerShell\v1.0\profile.ps1)

if ((Get-PSSnapIn -Name Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue) -eq $null )
{
     Add-PSSnapIn -Name Microsoft.SharePoint.PowerShell
}

Save the profile.

Next time you open the PowerShell ISE you will have all the Microsoft.SharePoint.PowerShell commandlets.
