Well that is about the last step windows performs after installation.
Setting the desktop up, and items on the start bar ect, and account settings.
And why it will freeze is because at that point you should, if used remove your usb flash disk.
What I mean is, is it still plugged in when doing the last step. if so remove it.
If the case try it Muhammad.
Let the system boot, without the usb connected.
Also change the boot order back to Hd to number 1 in the list of the bios.
The lock up may be because windows has to mount a usb drive as a storage device.
With it plugged in it may cause a halt.
As it is trying to work out the storage device.
Mass storage device/ usb flash drive.
The stick should be removed before the last step of setting up desktop.
