I have installed IIS. Seems to be running.
Now I have added an HTML file into c:\inetpub\wwwroot.
I checked Services, the World Wide Web Publishing Service has been started.
So, I expected that if I point my browser to localhost\myfile.html, it would run, but shows the error "This webpage is not available".
So in IIS Manager, I right-click on " Default Web Site", then choose Manage Web Site, then choose Start, upon which I get the error:
The process cannot access the file because it is being used by another process. ( Exception from HRESULT: 0X80070020)
