What does this mean? I don't understand your questions.

1) Are you asking what services run in Windows or possibly what services
are or possibly you have a program called "Windows Services"?

2) What do you mean "start a program manually"? Click on its shortcut or
Start>Run>some-executable.exe?

Windows Services is all the services that run or can be run in Windows XP?

Control Panel, Administrative Tools, Services. Left mouse click on a
service and you get a description on the left side. Double left mouse
click on a service and you get more information and you can Start, Stop,
Pause or Resume the Service. You can also change the Startup type from
Automatic, to Manual or Disabled.

Any particular reason you're interested in Windows Services?

Considering how you structured your question, a simple answer is that
they are startup programs.  They load whether you are logged on or
not.  They load when Windows loads.  They can have interdependencies
with other services (so some won't start until another has been
started).

If you don't what a service is for, don't be putzing around with it.
There would be a reason why you asked by you chose to hide that
reason.

Hello

Windows services are the services which are required by many programs on the
computer to run.  For example if you are using the internet< services like  
DNS client, DHCP should be started . Simlarly for accessing the windows
updates: services like, automatic updates, BITS and cryptographic files
sholud be enabled. If you are installing some software, and you get the error
message: Windows installer is not working. You sgouls check the windows
installer service.

click on start--> run---> type in " services.msc "  click on ok
You will get the services windows.
