Can any help me how to install webcenter sites on windows
can any one help me ..
This is the wrong forum, as it is not related to oracle webcenter.
Also look at what a small google search for "install oracle webcenter" turned up:
So I'd suggest you do what everyone else who'd install webcenter need to do: go through the documentation and try it yourself before asking someone else to abstract the manuals for you. If you get into troubles there is nothing wrong with asking for help in the correct forum.
