Ethernet connection has OS and device overheads but your headless setup will give benefits - its a tradeoff. cPlay will RAM load data before playback so Network streaming is not an issue.
- Welcome Screen.
You should implement the changes. This will force a password dialog. Minlogon optimisation removes this dialog (as you now logon as System Default). Benefits of Minlogon are huge and yes it will work with Networking enabled. Seger has a easier approach which you should look into.- cMP Mode.
This results in least OS bloat and is the best way to run cPlay (Optimise must be "Critical"). With your Lynx, you can also Suspend both lsass and svchost. cMP optimises use of CPU Cores. Running from Explore is a bad idea (this locks all threads to CPU0 and doesn't adjust priority).- Way Forward.
Start directly into cMP Mode (no logon/password dialog with Minlogon). In cMP, set "Process Explorer" or "Task Manager" as startup but instead run your Network app (CPlayList Editor?). See cicsMemoryPlayer.pth file for details. If CPlayList Editor can trigger starting cPlay by cMP then you have gained all benefits. Also remove cicsRemote.exe from cMP installation folder (this prevents cMP from running it).
Good start!

If I remove cicsRemote.exe from the cMP installation folder will this help sonically? Also I don't use touch screen either is it useful to remove this as well?

cicsRemote.exe provides the remote automation using a wireless mouse. If you remove this, you won't have remote control. However, it won't matter if you're not using a mouse, i.e. you can remove it. I tested this a long while back and found no differences. Its worth testing again - let us know.
There's nothing to remove if you don't have a touch screen.
I tried this (eliminating cicsRemote.exe from cmp folder) and although there is one less process in task manager it does not sound different to me after one day of listening.

Hi cics,
Seger's instructions worked well regarding removing the password prompt. I am running XP SP3. Is there a link which describes the benefits of using minlogon? If not, what are the benefits?
I can now boot directly into CMP critical mode, with CPlayListEditor starting automatically as you have suggested, through editing the cicsMemoryPlayer.pth file and setting startup to Process Explorer. Interestingly, the only manner I could get CPlayListEditor to start at startup was to create a batch file to start it. Referencing the command directly in cicsMemoryPlayer.pth doesn't work. I also tried hiding the command prompt that comes up from the batch file by using #H, but that keeps the batch file from being executed. Also, the cicsMemoryPlayer.pth file that came with the CMP software doesn't have a TaskManager entry in it. Do I have the correct version of the software?
Thanks very much. Now I can use a headless CMP without running any sort of VNC server. I need to make a couple more tweaks to the software (add phase, fast forward and rewind buttons), and make the usability a little more self explanatory. After that I'll make it available if anyone else cares about a headless CMP.

Minlogon implementation for SP3 is a problem - haven't seen one yet. Improvements are very significant and I would suggest installing SP2 on your spare partition. Minlogon benefits:
"Windows security overheads is reduced significantly and there's no logon prompt at startup☺ Boot time is faster. Sound improves as Windows footprint reduces (less overheads). Windows operates using '.Default' user. All user settings (Desktop, Appearence, foobar, ?) will need to be redone. It's worth rechecking all optimizations again."
Windows security subsystem causes each device IO to be secure - this includes audio output. Reduction in runtime overheads is significant.
Task Manager entry is not available in .pth file (as cMP internally uses Windows version). Your problem with Process Explorer is a surprise - be sure to use quotes for the program and there are no typos as cMP will not report on an error (something I want to fix in next release). #H/N/H is only applicable to RIPPER, CUE_PLAYER & PREP_PLAYER. I get cPlayListEditor to work without a .bat using the following:
PROCESS_EXPLORER "java" -jar "C:\Program Files\CPlayListEditor\CPlayListEditor.jar"
Power button is not available in cMP Mode. I have a HTPC which I shutdown by just holding the power button for a few seconds. Yes its a hard shutdown - I've been doing this for 1 year+ without any problems.
I use minlogon with sp3 running cMP2 without problems on my Lenovo laptop as optimized as possible.
That's very good to know.
Yes: boot from second non-cMP drive and substitute minlogon for winlogon all after running the registry change application. Then boot to cMP drive. Done. I suppose making the substitution when booted to safe mode from cMP drive would work just as well.
