A long delay at "Please Wait" or "Welcome"

Hello !
I have a PC with windows 7.
Is a new clean installation made 2 days ago.
Today I have noticed that windows takes a very long time on the screen " Please Wait" . Sometimes the same things happen to "Welcome" screen.
I clear the startup list.
I clear also all the startup item from windows registry.
I check the HDD and RAM but everything is ok.
I have installed all the windows updates and all the drivers updates.
I try some suggestions that I've found on internet like disabling the Network Locations awareness ...etc.

But nothing is working. Of course on safe mode , everything works fine.

I check the performance details about Event ID 100 , and these are the results :

What should I do ?
Thank you !

And why I'm not being held by my disk when running on safe mode ?
And why everything works ok after the Please wait and Welcome screen ?

Ok , and how you explain that after passes this screen , windows works very well in all programs ?

I'm using 3d studio max 2015 in this PC. do you think that demand on disk access from this program is lower that windows loading ?
Well this program is working very well.

Strange that you don't know it .Ok , this is a 3D graphical software from autodesk , and has a very large disk access demands.

another example.
Move data from a partition to another . I think do you know that this is all related with disk drive.
This process for very large files is done on a normal time like in other pc. not delay at all.
