examples <<~DOC
**Set the SeNetworkLogonRight Privilege for the Builtin Administrators Group and Authenticated Users**:
```ruby
windows_user_privilege 'Network Logon Rights' do
privilege 'SeNetworkLogonRight'
users ['BUILTIN\\Administrators', 'NT AUTHORITY\\Authenticated Users']
action :set
end
```
**Add the SeDenyRemoteInteractiveLogonRight Privilege to the Builtin Guests and Local Accounts User Groups**:
```ruby
windows_user_privilege 'Remote interactive logon' do
privilege 'SeDenyRemoteInteractiveLogonRight'
users ['Builtin\\Guests', 'NT AUTHORITY\\Local Account']
action :add
end
```
**Provide only the Builtin Guests and Administrator Groups with the SeCreatePageFile Privilege**:
```ruby
windows_user_privilege 'Create Pagefile' do
privilege 'SeCreatePagefilePrivilege'
users ['BUILTIN\\Guests', 'BUILTIN\\Administrators']
action :set
end
```
**Remove the SeCreatePageFile Privilege from the Builtin Guests Group**:
```ruby
windows_user_privilege 'Create Pagefile' do
privilege 'SeCreatePagefilePrivilege'
users ['BUILTIN\\Guests']
action :remove
end
```
**Clear all users from the SeDenyNetworkLogonRight Privilege**:
```ruby
windows_user_privilege 'Allow any user the Network Logon right' do
privilege 'SeDenyNetworkLogonRight'
action :clear
end
```
