Follow Ups:
Control Panel > System > Hardware TAB > Device Manager BUTTON > View MENU > Check ‘Show hidden devices’
With ‘Show hidden devices’ checked, much can be disabled. I’ve summarized by reply post all devices to be disabled including those noted previously.
Select View > ‘Devices by connection’ in Device Manager. Goto ACPI > Microsoft ACPI-Compliant System > PCI Bus. Compare with above after disabling devices.
PCI-PCI Bridge controllers are disabled as I don’t use any PCI Express interfaces. If using PCI-E graphics card, one of these must remain enabled.
On some mobos, you can also disable ‘PCI-ISA bridge’ and / or ‘ISAPNP’. On right-click, menu gives ‘Disable’ option. In my case, right-click menu only offers ‘Uninstall’. In this case device can be uninstalled which immediately reinstalls on reboot.
This applies to no Network stuff being used. Items ‘ViaIde & Standard IDE/ESDI Hard Disk Controller’ should NOT be disabled if using standard IDE or SATA interface. ‘ViaIde’ is specific to VIA mobo chipset. I’m able to safely disable these as I use SATA RAID 0.
Only do this if you don’t use any Networking functions.
This will require a reset of your video to 16 bit color, no video acceleration and uncheck ‘enable write combining’. Also make sure output resolution is set to native / default display resolution. Most new displays are either 1024 x 768 or 1280 x 1024.
Device Manager > Select 'Show hidden devices' under View menu > Expand 'Non-Plug and Play Devices'. Note use 'View devices by type' - the default view.Scan list and disable (right-click on item):
1. Beep
2. Serial (if it exists)I get a blacker background with this.
Good catch finding the expand 'Non-Plug and Play Devices'. There are several more devices now that I think can be disabled, and I am still experimenting.
I almost wish we could just run foobar with ms-dos since all these windows drivers loaded just add more grunge. I think we could also use another SYsinternals program called Autoruns to disect and disable everything loading..it's easy to see everything at least.

i only used it to make sure I didn't have any spyware running at first.
Anyway, I also disabled all the audio codecs that are launched, which I hadn't done before. I think that helped.
Play at your own risk concerning the newly exposed devices, but I disabled FIPS, Remote access stuff, extra devices that appeared under network adapters, and terminal services for keyboard and mouse. The network stuff will prevent your network card from working. If you don't cae about that you can also disable IPSEC.s good as these improvements are, I know the rest of my system can't take full advantage of high quality the transport is now. Extra power conditioning improvements could really help at this point, not to mention equipment upgrades.
I would like to disable kmixer and the others, but since I watch movies on the same pc, it locks up when some of these drivers are not loaded. Otherwise, I'd love to prevent them from coming up. Still, I'm glad you found this autoruns helpful; it's cool for what it does. Was there an audible benefit, or just a happy feeling knowing those drivers weren't running.
I've been busy, but I'd still like to:
1. Upgrade from factory dell power supply, hopefully a fanless or quieter solution, since it is still audible from my listening position. Any ideas to power 4 sata hard drives, nvidea pci-e video card, rme sound card without audible or dc noise?
2. try to experiment with underclocking/voltage modifications.
3. experiment with RAMDisk.
4. See what other hidden device manager devices I can disable/or disable with autoruns.
There are always more improvmeents to be made, so I'm sure further poking around will reveal some more. Good stuff lately, though!
I'll do a separate post on Autoruns as there is definite benefit in other areas.
In Drivers TAB, you can disable many Windows audio components - just uncheck items. So far, I have these 6 disabled:
1. aec (acoustics echo canceler)
2. DMusic (synthesizer)
3. drmkaud (descrambler)
4. kmixer (as last!)
5. redbook (filter)
6. splitter
There's also usbaudio (which I don't have installed on my transport). I only have sysaudio enabled for WDM drivers (and don't know if theres other audio components).
Under Explorer, 'Installed Components', its set as per picture.
If you plan to reinstall soundcard driver or make changes to Windows Sounds, etc. all these drivers must enabled and system rebooted. Otherwise, will get unpredictable results.
