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)

| 52.Service Name:-SwPrv |
| Executable Name:-svchost.exe -k swprv |
| Log On As:-LocalSystem |
Description:-Manages software-based shadow copies taken by the Volume Shadow Copy service. A shadow copy enables you to create a copy of a disk volume (or apparent copy) that represents a consistent read-only point in time, for that volume. This point in time then stays constant and allows an application (like backup) to copy data from the shadow copy to tape.
There are two general classes of shadow copies:
- Hardware in which a mirror of two or more disks are split into separate volumes. One of the two volumes then remains the working set and the other one can be mounted separately.
- Software. A software volume uses a copy on write scheme to copy all sectors of a volume that change over time into a differential area. When the shadow copy is mounted, all non-changes sectors are read from the original volume and all sectors that have changed are read from the difference area.
Shadow copies can resolve three classic problems with backup:
- The need to delete share flags in a filter driver in order to backup files that have been opened for exclusive access. The problem of backing up a file as it is changing. Without a shadow copy or a way to suspend the application the result of doing this is typically a corrupt backup.
- Allowing a system to remain active while the shadow copy is being performed. Tax time problems are a good example that organizations cannot afford the time for a backup window.
- In addition, leveraging the snapshots approach and using the same communication channels to build information transfer between application and backup tools.
If this service is stopped or disabled, software-based volume shadow copies will not be managed.

| 53.Service Name:-SQLSERVR |
| Executable Name:-SQLSERVR.EXE - sUDDI |
| Log On As:-NetworkService or Domain Account |
Description:-This service is installed when installing the Universal Description, Discovery, and Integration (UDDI) feature of the Windows Server 2003 family of operating systems which provides UDDI capabilities within an enterprise. The Microsoft SQL Server database engine is the core component of this feature.
The SQL Server service utilized by UDDI manages all of the files that comprise the databases owned by an instance of SQL Server. It is the component which processes all Transact-SQL statements sent from SQL Server client applications. The MSSQL$UDDI (SQLServer.exe) service allocates computer resources effectively between multiple concurrent users. It also enforces business rules defined in stored procedures and triggers, ensures the consistency of the data, and prevents logical problems such as having two people trying to update the same data at the same time.
UDDI is an industry specification for the description and discovery of Web services. The UDDI specification builds on the Simple Object Access Protocol (SOAP), Extensible Markup Language (XML), and HTTP/S protocol standards developed by the World Wide Web Consortium (W3C) and Internet Engineering Task Force (IETF). UDDI services are standards-based XML Web Services designed for enterprise developers to efficiently publish, discover, share, and reuse Web Services directly through their development tools. Built on the Microsoft Framework, UDDI services use proven Microsoft SQL Server technology and tools to provide a scalable storage mechanism. IT Managers can leverage UDDI services' support for standard categorization schemes and Active Directory authentication, allowing for easy integration within an enterprise environment.
If stopped or disabled, the UDDI SQL Server database will no longer be available on this machine and clients will no longer be able to query against/access the data in its databases.

| 54.Service Name:-MSSQLServerADHelper |
| Executable Name:-sqladhlp.exe |
| Log On As:-LocalSystem |
Description:-This service helps Microsoft SQL Server and Microsoft SQL Server Analysis Services to publish information in Active Directory when SQL Server Service and Analysis Server Service are not running under LocalSystem account. This service is dynamically started by an instance of SQL Server or Analysis Manager when needed. The service is stopped as soon as it has completed its work. This service should always be run from LocalSystem account and should not be started manually from console.
There is only one MSSQLServerADHelper service on a computer. All instances of Microsoft SQL Server and Microsoft SQL Server Analysis Services use it when needed.
