Before proceeding to installation we will have to disable
user account control (UAC) and Internet Information
Services (IIS) for the time being. You can enable them
again once installation is complete.
To disable UAC go to
“Start>Control Panel>User Accounts” there you will
find an option “Turn User Account Control on or off”
just click on it and uncheck “User Account Control to
help protect your computer”, click “OK”.
To disable IIS go to “Start>Control Panel>Programs and Features”
on the leftmost side you will find an option
“Turn Windows features on or off” click on it and
uncheck “Internet Information Services”, click “OK”
and restart your computer.
