Digging into running processes and services via the command-line

Due to the comments in my blog entry about the RemoteRegistry process, I figured I would try to educate myself about it and share that learning with all of you. In my attempt to educate myself on the RemoteRegistry process, I am having fun with a variety of command-line tools, such as SC and TaskList. These tools are useful for digging into any process, but my examples are focused on RemoteRegistry. Here is what I have dug into so far; complete with the description and outcome of each command-line task that I have found interesting:


Display services in each process. I deleted everything except the svchost.exe instance that is running RemoteRegistry:

C:\>tasklist /SVC  

Image Name                   PID Services

========================= ====== ============================================

svchost.exe                  256 LmHosts, RemoteRegistry, SSDPSRV, WebClient



Display a set of tasks that match the given criteria specified by the filter. The filter is for PIDs that equal “ 256”. Notice the extra space before the three-digit 256:

C:\>tasklist /FI "PID eq  256"

Image Name                   PID Session Name     Session#    Mem Usage

========================= ====== ================ ======== ============

svchost.exe                  256 Console                 0      1,812 K



Display the extended status of the service:

C:\>sc queryex RemoteRegistry

SERVICE_NAME: RemoteRegistry

        TYPE               : 20  WIN32_SHARE_PROCESS

        STATE              : 4  RUNNING


        WIN32_EXIT_CODE    : 0  (0x0)

        SERVICE_EXIT_CODE  : 0  (0x0)

        CHECKPOINT         : 0x0

        WAIT_HINT          : 0x0

        PID                : 256

        FLAGS              :



Query the configuration information for the service:

C:\>sc qc RemoteRegistry

[SC] GetServiceConfig SUCCESS


SERVICE_NAME: RemoteRegistry

        TYPE               : 20  WIN32_SHARE_PROCESS

        START_TYPE         : 2   AUTO_START

        ERROR_CONTROL      : 1   NORMAL

        BINARY_PATH_NAME   : C:\WINDOWS\system32\svchost.exe -k LocalService

        LOAD_ORDER_GROUP   :

        TAG                : 0

        DISPLAY_NAME       : Remote Registry

        DEPENDENCIES       : RPCSS



So what do I do with this information now that I have it? Well, I haven’t gotten that far yet. If I do, I’ll update my blog.
