Man, just replace group name in script:

$visitorsSPGroup ="NT AUTHORITY\authenticated users"

Hi,

Using power shell loop through all the items in your library and then add domain\ntauthenticated users group to each of the item with read permission level

Hi,

Below code will add "Contribution" permission to a list, you can use it with a little customization.

# Alter Item-Level Permission settings and assign "Contribute" role definition to the visitors group
# (c) 2011 Morgan de Jonge
 
# Specify the name of the visitors SharePoint group
$visitorsSPGroupName = "Example Site Visitors"
 
$spSite = Get-SPSite "http://portal.contoso.com"
# We'll assume the list is in the top-level site in the site collection
$spWeb = $spSite | Get-SPWeb
# Look up the list named "Questions"
$questionsList = $spWeb.Lists["Questions"]
 
# Set the Read access Item-level permissions settings to "Read items that were created by the user"
$questionsList.ReadSecurity = 2
# Set the Create and Edit access Item-level permissions to "Create items and edit items that were created by the user
$questionsList.WriteSecurity = 2
 
# Assign the "Contribute" RoleDefition to the site's visitors group
$visitorsSPGroup = $spWeb.Groups[$visitorsSPGroupName]
$questionsList.BreakRoleInheritance($true)
$assignment = New-Object Microsoft.SharePoint.SPRoleAssignment($visitorsSPGroup)
# Assuming this is a default site, we'll look for a role definition of the type "Contributer".
# This way, the script will also work with SharePoint sites created in languages besides English.
$assignment.RoleDefinitionBindings.Add(($spWeb.RoleDefinitions | Where-Object { $_.Type -eq "Contributor" }))
$questionsList.RoleAssignments.Add($assignment)
 
$questionsList.Update()
 
$spWeb.Dispose()
$spSite.Dispose()

Thanks,
