Windows likes to write a file after each boot that can drive disk usage to sky.The size of this file varies from user to user.Some report only 10MB while others have to wait more than 10 minutes after boot for a 160MB file to be written step-by step into disk.Solution is to delete this file.It will not be created again after deletion - C:\Windows\System32\wdi\LogFiles\BootCCKL.etl

It's a logfile for Circular Kernel Context. It can be safely deleted. Don't know if this file is related to the high disk usage upon boot though.
Normally the high disk usage at boot is related to the Superfetch service.
In case of this issue, you should alter the following regkey :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters

On the right side look for a key named: EnableSuperFetch

This decides if and how prefetch runs, here are the value and what they do:
0: Disable
1: Cache applications
2: Cache startup or bootup
3: Cache Everything

Set it to "2" and press OK.

Leave Prefetcher at default (1)

close regedit


Never disable it, that would be stupid. BUT altering it to "2" makes a hell of a difference when suffering these high disk accessing at boot.
Superfetch will then be enabled for caching the bootcycle only, and not applications, which greatly reduces the amount of data that needs to be cached upon boot. People who have the issue should see a big difference when booting up.
