installutil.exe/u <your service name.exe> -->For uninstall

u have to use this command in visual studio 2005 -> visual 
studio command Prompt -> write this above command..

I Think,For Installing Windoes Service 
i)First Create new Project and in Right Side Expand Visual 
C# and select windoes service.
ii)Give name to your service.
iii)Write Your code IN OnStart Event.
iv)Add New Project To Your Solution and select 'setup' 
project which is in other project templates
v)and set Project output type to primary output which is in
FileSystem(Service Setup).
vi)Right click Your service Setup in solution Explorer And 
click install then your service is install in your system
vii)Go to controlpanel And click Administrtivetools(make 
sure u have login as a Administrator (or) you are part of 
Administrative Group) and then click services.
viii)Go to your service name and right click it and click 
start then your service will run
