Titolo: Processi

Ho installato winxp pro
volevo sapere per cosa servono i processi che trovo su
taskmanager e quelli che non servono.
Ora vi elenco i processi visualizzati in taskmanager  appena il pc č stato
avviato:
Explorer.exe
svchost.exe
winlogon.exe
navpw32.exe
spoolsv.exe
svchost.exe
svchost.exe
csrss.exe
svchost.exe
mdm.exe
service.exe
ctfmon.exe
acrotray.exe
navpsvc.exe
lsass.exe
smss.exe
system
ciclo idle del sistema
Come noterete il processo svchost.exe viene caricato 4 volte perchč?
Ciao e grazie1000

: Come noterete il processo svchost.exe viene caricato 4 volte perchè?
Dalle release notes ufficiali di xp... spero tu capisca l'inglese.
The last area of reliability improvements is in the area of the services
infrastructure. Prior to Windows 2000, some services shared a process with
other services and some ran in their own process. Windows 2000 introduced
the generic service host process, Svchost.exe. The goal was to reduce system
resources by consolidating the various processes hosting built-in operating
system services into a single process. Or, it could permit the system
administrator to configure the system to run certain services in their own
processes, which would prevent one service from corrupting the private
memory of other unrelated services (this capability is not documented or
supported yet).
If you look at the Windows XP process list in Task Manager (see Figure 8),
you will notice at least four Svchost.exe processes: two running under the
SYSTEM account (sometimes referred to as LocalSystem) and two running under
two new service accounts: NETWORK SERVICE and LOCAL SERVICE.
One of the two Svchost processes running under SYSTEM hosts the bulk of the
services, 29 of them in total. The second one hosts a single service, Remote
Procedure Call (RPCSS). The reason this service needs to be in a separate
process is that user-written DLLs are loaded into this process. By having
RPC running in its own process, these DLLs cannot adversely affect the
operation of the other built-in operating system services. The Svchost
process running under NETWORK SERVICE hosts a single service, the DNS
Client. The Svchost process running LOCAL SERVICE hosts the TCP/IP NetBIOS
Helper, Remote Registry, Simple Service Discovery Protocol, and Web Client
services.
The reason for the two new service accounts is to improve system security by
reducing the privileges that services run with. LOCAL SERVICE is a built in
account that doesn't need a password to log on. The account has only a few
privileges, and is not a member of the local administrators group. So, if a
service that is running under this account is compromised, it cannot take
down the whole machine. LOCAL SERVICE also has no network credentials, so
attempts to access a machine on the network will connect with the null
session. The NETWORK SERVICE account has the same set of privileges as LOCAL
SERVICE, but has access to the machine's credentials for outbound
connections, similar to the SYSTEM account.
