I'm running an app on XP Home that uses a lot of the hardware.
It's largest in the Mem Usage column in Task Manager.
120,000 vs 32,000 for explorer.exe (approximate numbers)

But if i sum the smaller apps memory usage, they total to a nice quantity that i'd like to devote to this hungry app.

To reduce need for services, I:
Disconnect the lan cable to router.
Shutdown AV, and software firewall.
Then of course, there are some obvious things that can't be shutdown


So, question is if I disconn from LAN and the net, what can be shutdown?

It's up to me to deal with what this app may need.
If i'm not going to print, can i shutdown spool?

some of the svchost can be shutdown in Task Manager. Seems not best way.. i shut 2 or 3, then one shutdown a
message popped up: "NT ... (need) RPC call.. am shutting win down.. save open apps.."

But it looks as if i can shutdown the shuttable svchost by examining certain services (in Services 'folder')
Example, Windows Audio is actually ...svchost... netsvc
Windows Audio is not a dependency for anything and shutting Windows Audio won't matter to its dependencies.
Correct?


System Idle Process +
System +
smss.exe +
csrss.exe +
explorer.exe +
lsass.exe +
winlogon.exe +
spoolsv.exe ?
svchost.exe + (some tbd)
svchost.exe s (some tbd)
services.exe +
mmc.exe s (is services folder)
wdfmgr.exe ?
taskmgr.exe s (is Task Manager?)

s shutdown, in either own UI, Task Manager, or Services
+ keep running
? don't know

i have a related second question.
i can go into Services, and edit the startup mode from Automatic to Manual. then i can Stop that service.

will my edit from Automatic to Manual remain after full restart of the computer?

TIA
 
spoolsv.exe is the Print Spooler.

mmc.exe only runs when you have an .msc file open, i.e. services.msc,
eventvwr.msc, console1.msc, etc. Any Administrative Tools.

wdfmgr.exe is part of Microsoft Windows Media Player 10 and above. This
process decreases compatibility problems whilst the product is in use. This
program is a non-essential process

Disable this POS!

If you do not have a hardware player, you can set the Windows User Mode
Driver Framework service Startup type setting to Disabled.

RESOLUTION
To resolve this issue, set the Windows User Mode Driver Framework service
Startup type setting either to Disabled. To do this, follow these steps:

1. Click Start, click Run, type services.msc in the Open box, and then click
OK.
2. In the list of services, right-click Windows User Mode Driver Framework,
and then click Properties.
3. Click the General tab.
4. In the Startup type box, click Disabled and then click OK.
5. On the File menu, click Exit.

Windows Task Manager after you install Windows Media Player 10

If you have XP Pro, you can use tasklist /svc to see what services
svchost.exe is running.

See this.

Yes. However, in Manual, the service is loaded on demand, if needed.

Service Startup States

<quote>
A service has 3 basic startup states:

Disabled: The service will not be loaded (Some programs stop working, won't
take memory and quick boot time)

Manual: The service will be loaded on demand (Slow program start, won't take
memory and quick boot time)

Automatic: The service is loaded at boot time (Fast program start, will take
memory and slow boot time)

If you have a typical installation, many services are configured as
"automatic" (that is, they start automatically when the system starts or
when the service is called for the first time). If a service is configured
as "manual," you must start the service manually before it can be loaded by
the operating system and made available for use. If a service is configured
as "disabled," it cannot be started automatically or manually.

yep.

particularly the answer to question about start services, manual vs auto being retained after restart windows. it means i'll
have to remember to reset each service startup to auto for next win restart.

other parts of your reply confirmed or gave extra info beyond my sketchy knowledge. also appreciated.

wdfmgr.exe
now when i look at task manager list it's gone. maybe shutting Windows Audio did that.
spoolsv.exe
not printing so shutoff


some of the AV services seem to be "sticking", i guess whatever happens happens. looks like i've got about all that can
be stopped stopped.

i recall a few months ago, converting some more obviously extraneous services (cdilla, etc) to manual, so i guess those
have remained off since then. i took notes back then, but nothing's gone wrong, so...

oops, bad memory. using the net in another from from the computer being "lightened"
Windows Audio may have shutoff one of the svchost.

but i googled a little more about "hardware".. mp3 players, etc... don't have any. so yes, i edited Windows User Mode
Driver Framework wdfmgr.exe (which was the actual path/exe) disappeared from the list.

thanks again.
 
I never heard of C-Dilla before. This is NOT an XP service, it is a 3rd
party service.

Service Name: C-DillaCdaC11BA
Run from: C:\WINDOWS\System32\drivers\CDAC11BA.EXE

<quote>
cdac11ba.exe is a process belonging to MacroVision safeCast copy protection
software. This piece of software allows manufacturers to protect their
products from illegal duplication. Disabling, or deleting this process may
corrupt the product it was supplied with.

C-Dilla [ cdac11ba.exe ] was the name of a company that was acquired by
Macrovision in 1999. Some Macrovision SafeCast technology is derived from
earlier C-Dilla products, and some of the files and folders used by
SafeCast-licensed applications today still have "C-Dilla" in their names.

For example, TurboTax has been known to install and use C-Dilla. What
disturbs users is that Macrovision / C-Dilla License Management System can
be installed without clear notification and remains after you uninstall the
main application. To uninstall this software, you have to go through the
uninstall procedures like you would for any software, and select this
product.
