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)
|
| 94. Service Name:- Sacsvr |
| Executable Name:-svchost.exe -k netsvcs |
| Log On As:-LocalSystem |
Description:-You can use the Special Administration Console (!SAC) to perform remote management tasks if the Windows Server family operating system stops functioning due to a Stop error message.
The main functions of !SAC are to:
- Redirect Stop error message explanatory text.
- Restart the system.
- Obtain computer identification information.
The Special Administration Console (!SAC) is an auxiliary Emergency Management Services command-line environment that is hosted by Windows Server family operating systems. It also accepts input and sends output through the out-of-band port. SAC is a separate entity from both SAC and Windows Server family command-line environments. After a specific failure point is reached, Emergency Management Services components determine when the shift should be made from SAC to !SAC. !SAC becomes available automatically if SAC fails to load or is not functioning.
If this service is stopped or disabled, SAC services will no longer be available.

| 95. Service Name:-SSDPRSRV |
| Executable Name:-svchost.exe -k LocalService |
| Log On As:-LocalService |
| Description:-Enables discovery of UPnP devices (Universal Plug and Play) on a home network.
This implements the SSDP Discovery Service (Simple Service Discovery Protocol) as a Windows service. The SSDP Discovery Service manages receipt of device presence announcements; updating its cache and passing these notifications along to clients with outstanding search requests. The SSDP Discovery service also accepts registration of event callbacks from clients, turns these into subscription requests and monitors for event notifications; passing them along to the registered callbacks. This service also provides hosted devices with periodic announcements.
By default, this service is Manual. If the Universal Plug and Play Device Host Service is started, the SSDP Discovery service will start as well. When this service is stopped, the SSDP cache is cleared, and new devices coming onto the network will not be discovered, and new searches for devices can also not be made.

| 96. Service Name:-SQLAgent$UDDI |
| Executable Name:-SQLagent.exe -i UDDI |
| Log On As:-Network Service or Domain Account |
Description:-The SQL Server Agent UDDI supports features allowing the scheduling of periodic activities or the notification to system administrators of problems that have occurred with the server. The SQL Server Agent components that implement this capability are:
- Jobs: Defined objects consisting of one or more steps to be performed. The steps are Transact-SQL statements that can be executed. Jobs can be scheduled, for example, to execute at specific times or recurring intervals.
- Alerts: Actions to be taken when specific events occur, such as a specific error, errors of certain severities, or a database reaching a defined limit of free space available. The alert can be defined to take such actions as sending an e-mail, paging an operator, or running a job to address the problem.
- Operators : People identified through their network account or e-mail identifier (ID) who can address problems with the server. They can be the targets of alerts, either through e-mail, a pager, or a net send network command.
The service name of SQLServerAgent$UDDI applies only to the Agent service associated with a default instance. SQL Server Agent services associated with named instances are named SQLAgent$InstanceName.
If service is stopped or disabled no replication will occur, it will break all scheduled jobs and alert/event monitoring and auto restart of the SQL Server service.

| 97. Service Name:-Sens |
| Executable Name:-svchost.exe -k netsvcs |
| Log On As:- LocalSystem |
Description:-
Tracks system events such as Windows logon network and power events. Notifies COM+ Event System subscribers of these events.
Disabling this service has the following effects:
- Win32 APIs IsNetworkAlive() and IsDestinationReachable() will not work. These are mostly used by mobile applications and on portable computers.
- SENS interfaces will not work properly. In particular, SENS' Logon/Logoff notifications will not work.
- SyncMgr (Mobsync.exe) will not work properly. This depends on connectivity information and Network Connect/Disconnect and Logon/Logoff notifications from SENS.
- COM+ EventSystem will try to notify SENS of events, but will not be able to.
