Windows sits on the "Please Wait" screen for a long time during boot?

I have a PC running a clean installation of Windows 7. I have noticed that Windows takes a very long time on the "Please Wait" screen during boot. I have cleared the startup list and also all of the startup items from Windows registry.

I have also tried several suggestions that I've found on internet like disabling the Network Locations awareness, etc, but nothing is improving the situation.

Of course in safe mode, everything works fine.
