Port 80

Unblocking it for use by Apache or IIS.

First clues

Run the command netstat -ano | find ":80" . The last column will tell you the PID of anything that might be running on port 80. You can see what the application is by looking at Windows Task Manager : Processes. Ensure you check the box "Show processes from all users". You can make the PID column viewable by selecting menu item View : Select Columns. If the PID is 4, then you've got additional problems, because you cannot just kill that process.

SQL

Go into services, and disable anything to do with SQL. This is a known fix on 16-Jan-2012 for the PID 4 problem.

http.sys

it might be that Win 7 is running a service called http.sys . The fix is:
  1. Launch RegEdit
  2. Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP
  3. Add a new DWORD (32-bit) value
  4. Name it 'NoRun' not including the quotes
  5. Double click the new property
  6. In the Value data field type '1' not including quotes and click OK
  7. Re-boot your computer
