Here is the script to convert users from windows authentication to claim using PowerShell.

In SharePoint sometimes required to use claims authentication of user, at the time if user has window authentication we can convert its authentication into claim identity.

$m = [Microsoft.SharePoint.Administration.Claims.SPClaimProviderManager]::Local
Add-PSSnapin Microsoft.SharePoint.PowerShell -ea silentlycontinue
$user="User Name Here"
Function Get-SPClaim
{
   param ([string]$user)
   $claimType =[Microsoft.SharePoint.Administration.Claims]::SPIdentifierTypes.WindowsSamAccountName
   return $m.ConvertIdentifierToClaim($user, $claimType)
}

It will return claims identity of user.
