Loading of system files

[Richard Urban]

During the boot to Windows XP, what is it that controls the loading of .sys
files? The reason I am asking is that I have 13 drivers that are apparently
called - but do not load. I have found entries for only four of them in the
registry.

Where may the others be? Calls from the kernel? Sub calls due to another
driver that has already loaded?

Some possibilities I have considered:
1. Left over from programs long since uninstalled
2. I turned off an option somewhere but the driver is still being called
3. Drivers installed with the system, in case I decide to connect some
specific device

Now, if I were to eliminate the initial call for these drivers (which
apparently my system doesn't need) the boot up process "should"? be faster -
YES/NO?

These are the files that do not load, as per the ntbtlog.txt:

Did not load driver \SystemRoot\System32\Drivers\NDProxy.SYS
Did not load driver \SystemRoot\System32\Drivers\lbrtfdc.SYS
Did not load driver \SystemRoot\System32\Drivers\Sfloppy.SYS
Did not load driver \SystemRoot\System32\Drivers\i2omgmt.SYS
Did not load driver \SystemRoot\System32\Drivers\Changer.SYS
Did not load driver \SystemRoot\System32\Drivers\Cdaudio.SYS

Loaded driver \SystemRoot\System32\Drivers\VET-FILT.SYS
Did not load driver \SystemRoot\System32\Drivers\VET-FILT.SYS

Did not load driver \SystemRoot\System32\Drivers\i8042prt.SYS
Did not load driver \SystemRoot\system32\DRIVERS\kbdhid.sys
Did not load driver \SystemRoot\System32\Drivers\PCIDump.SYS
Did not load driver \SystemRoot\system32\DRIVERS\rdbss.sys
Did not load driver \SystemRoot\system32\DRIVERS\mrxsmb.sys
Did not load driver \SystemRoot\system32\DRIVERS\ipnat.sys

I am going to eliminate all references from the registry and boot the system
as an experiment. My hardware has not changed for months and I don't see
making any immediate additions that may need these drivers. Yes! I just
imaged my system so that if it blows up I can be back to where I am in 6-8
minutes.

Thanks bunches!

I have entries for each of those (minus the .sys extension) under

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

(with the exception of vet-filt.sys which Google suggests is antivirus
related)

As I understand it, the value of the "start" registry key value, under each
entry, determines the type of startup

ie
4 - disabled
3 - manual
2 - automatic
1 - system
0 - boot


Of those you list they all seem to be "system" startups here, other than
"NDProxy" and "IPNat" which are "manual" startups.

So changing the value of the "start" key from 1 (=system) (or 3 = manual) to
4, should theoretically disable that particular service from startup (NB
completely untried and untested)

That is a good start. Thank you!
