The Deep description on Windows Services
We have tried our best efforts to explore the deepth of windows services and all the given information is gathered from Microsoft notes (As its microsoft product)

| 58.Service Name:-NetDDE |
| Executable Name:-netdde.exe |
| Log On As:-LocalSystem |
Description:-Provides network transport and security for DDE (dynamic data exchange) by applications running on the same computer or on different computers. You can create Network DDE "shares" programmatically or by using DDEshare.exe on your computer, and make them visible to other applications and computers. Traditionally, the user creating the share will create and run a server process to handle incoming requests from client processes and/or applications (running on the same computer or remotely); once connected, these processes can exchange any kind of data over a secure network transport.
This service is disabled by default on Windows. If the service is disabled, any application that depends on NetDDE will time out when it tries to start the service. If an application on a remote computer is trying to start NetDDE on a different computer, it will appear as if that remote computer is not found on the network. If this service is configured as Manual, it is only started when invoked by an application that uses NetDDE, such as Clipbrd.exe or DDEshare.exe. In addition, applications running on remote computers can send messages to other computers that will invoke the NetDDE service.

| 59.Service Name:-NetDDEdsdm |
| Executable Name:-netdde.exe |
| Log On As:-LocalService |
| Description:-Manages shared DDE and is used by Network DDE. This service is used only by Network DDE to manage shared DDE conversations. You can create and "trust" DDE shares by using DDEshare.exe to allow remote computers and applications to connect and share data. This service maintains a database of these DDE shares, including information on which ones are trusted. For each request for a connection from, or "conversation" with, an application, this service queries the database and validates security settings to determine if the request should be granted.

| 60.Service Name:-NLA |
| Executable Name:-svchost.exe -k netsvcs |
| Log On As:-LocalSystem |
Description:-Collects and stores network configuration information such as IP address and Domain name changes as well as location change information and notifies applications when this information changes. The Network Location Awareness Service component supports the Network Location Service. This component provides the infrastructure that informs applications and the operating system of the network connections on a specific computer and to adapt to that computer's connectivity. This component implements the NS_NLA Windows Sockets namespace.
This component allows applications to enumerate network connections, obtain information about each connection, and request notification when the connections change. The connection information provides important networking data, such as the connection speed and connection type.
This service will automatically start when the start up type is Manual. Disabling this service stops network location awareness functionality. This behavior occurs because NLA is a demand-start service and it is used by several critical system components (including Winlogon.exe). When you stop the service, these other services have their change-requests cancelled, which they immediately try to re-establish thereby demand-starting the service again almost instantaneously. NLA correctly reports to the SC thread, which requested the stop, that the service stopped successfully. However, Winlogon.exe or another service immediately restarts before you are able to verify the status in the Microsoft Management Console (MMC) snap-in.
