Client server runtime process & csrss.exe

Question

Windows 8.1 64bit,  9/30/2014

i have 2 client server runtime process running, is it normal? when i click on them & chose open file location both show csrss.exe as source, so it should be normal?

so if open file location shows csrss.exe located in C:\Windows\System32 with both, then its normal?

Task Manger under Detail Tab i see 16 csrss.exe running & all are running under System, is that also normal?

today there is 26 csrss.exe running

Answer 1

u have no idea what happened, i got both Process Monitor & explorer, i messed up double clicked on csrss.exe & that opened a new csrss.exe in task manager under my user, then i tried to kill the process, but it only suspended it, then i was thinking maybe after restart it lets me remove it totally from task manager, i made restart & what do i see when i open task manager? i see only 2 csrss.exe running, LOL sometimes messing up fixes the problem

maybe this what some call zombie processes, they were in use once & when the process stopped they were stuck?

but all csrss.exe seemed legitimate, & no infection

but csrss.exe is not the only process that has more then 2 running & some over 10, one i counted it is 25

ok this are gone to, maybe this were connected to csrss.exe issue, but i have 10 svchost.exe, this should be normal?

some processes disappeared, example LogonUI.exe is no longer running, i had 25 LogonUI.exe running before, with restart it booted, i hope that PC will start tomorrow to, i hope i did not mess up something & it wont start, or i messed up PC security, made security holes

Answer 2

One solution is to stop looking in Task Manager, that is what Nelson did when he placed his telescope up to his blind eye.  I hope you have no more problems with csrss.exe.

Answer 3

does LogonUI.exe really run right new? is it just not showing? if its not running then i would have error message or problems with display? it would be funny if tomorrow i have all the 26 csrss.exe back

is LogonUI.exe running & just hidden, was it normal that LogonUI.exe was shown in task manager before? or is it  normal when its hidden? will it effect gaming? cant test, no games installed right new

Answer 4

I thought LogonUI.exe was something to do with logging on?  It might not need to run all the time.  At the moment, I am logged in to Windows and don't see it listed in Task Manager.  I do have a Winlogin.exe running.

Answer 5

what i read about, LogonUI.exe it has something to do with welcome screen & win graphics (it is also mentioned its connected to log on), maybe it means it means welcome screen

LogonUI.exe implements the graphical user interface shown when a user is asked to log in to the local machine. This is a core component of Windows and should be left alone

if i understand this correctly

it should not be listed in task manager

before LogonUI.exe runned from PC start to shutdown all the time & 25 LogonUI.exe were running

but ur 98% right, it is connected to-log on, but it seems to be connected to few things more then just Log-on, from what i read

when i looked screen shots from win7 it was on task manager, guess its normal for win7 & older

u know what happens to notification icons when u restart Win Explorer, also what happens to icons of programs that are uninstalled, i think u do, what i did & what happened to the processes as a result seem to be the same as the thing with Explorer restart, like task manager got reset like notification area with Explorer restart

its good to know that there is at least 1 user that does not have LogonUI.exe running, it makes it less suspicious
