Get list of running processes

I'm working on a Windows machine and would like to get the list of all running processes directly from R (basically process id and path to the program which is running).

I know Sys.getpid() gets me the process id of the current R process but does there also exist something to get me all processes running on the machine as I would get in Linux with top or ps -x

You can use tasklist:

system2( 'tasklist' , stdout = TRUE )
  [1] ""                                                                            
  [2] "Nom de l'image                 PID Nom de la sessio Num‚ro de s Utilisation "
  [3] "========================= ======== ================ =========== ============"
  [4] "System Idle Process              0 Services                   0        24 Ko"

EDIT to get the R process:

grep("^rsession",readLines(textConnection(system('tasklist',intern=TRUE))),value=TRUE)
[1] "rsession.exe                  6772 Console                    1   387,420 Ko"
[2] "rsession.exe                  7984 Console                    1    48,436 Ko"
[3] "rsession.exe                  1272 Console                    1    80,572 Ko"
