To many this might seem like an odd question. I mean itâs pretty easy to see if your mail program or word processor is running, right? Well, yes. But thereâs so much more you donât see. Todayâs operating systems are quite complex and doing nothing your machine might have a dozen different processes running.

In the Windows 9x world (Windows 95, 98 and Me), CTRL+ALT+DEL brings up a dialog box that lists almost all of the processes running. I say almost because portions of the operating system itself might not be represented. Thatâs by design since in Win 9x that dialog isnât really there to give you information but rather to allow you to terminate unresponsive programs.
In Windows XP (and its predecessors Windows 2000 and Windows NT) the system includes a built in âTask Managerâ. There are many ways to run it, but my favorite shortcut is to right click on the clock in the task bar and select âTask Managerâ. It too will show you a list of applications running which may be very short much like under Windows 98. However under the Processes tab youâll find a list of all processes running on your machine â there will be many more, especially if you select the Show processes from all users checkbox. (Hint: you can click on the columns in Task Manager to sort the output by that column which is particularly handy when you want to see whoâs using the most memory or CPU time.)
Given the difference in size between the list of applications running and the list of processes running it begs questions like âWhy?â And âWhatâs that difference between the two?â.
A simple answer is this: a process is a single running program and an an application consists of one or more processes. If youâve got Microsoft Word running youâll see âMicrosoft Wordâ in the application list and winword.exe in the process list. All those other processes? In a sense theyâre running as part of the operating system âapplicationâ.
But what are they? Well thatâs going to vary a lot from machine to machine based on two things: the software installed and the hardware installed. Certainly obvious items might include your instant messaging client, or other programs you use and know about. However when you install some software packages they may cause additional processes to run on your machine even when youâre not running the application. Examples include Real Player or QuickTimeâs update services, a fax programâs receive monitor, or a virus scannerâs real-time virus scanning process. The same applies for hardware, many hardware drivers include additional processes that run all the time.
Thereâs no one answer for determining exactly what each process running on your machine is, however I do cover many of the steps you can take to figure it out in this previous article: Whatâs this program running on my machine?.
When i open task manager the processes tab is just plane grey and does not show anything. Do you no what the problem is and how i could fix it?
Hmm unfortunately, I have the exact same problem, any fix ?
I have seen reference to it only as the result of a virus; SdBot. My advice: update the virus signatures and scan again. ALSO, I *only* saw reference to this from Sophos.com â I would hope the other virus folks have this one, but if not, perhaps Sohpos is worth a check. (Iâd be interested in hearing the results.)
On my wifeâs Sony laptop (PCG-GRZ610) whenever I open task manager (Windows XP), by whatever methor, I get only a single unlabled pane (not even the blue label and red X at the top) with applications running, and no tabs to allow you to see processes running.
Iâve never seen this behavior on an XP machine.
Any ideas?
Thanx

I would like to find out how to interrogate the
list of âprograms runningâ from within a C or Basic program. This way I could determine, for example, whether PRFILE32.exe had already been launched or needed launching. This would not be a problem for programs that only allowed a single instance of themselves to be active.
Dear sir ,
I am facing a problem in slow opeartion of the system in WIN 2000 and its fast in WIN XP⊠i have deleted all temp files as well recycle bin,,,, can you help me out
how do i know what is supposed to be running on my computer
Hi Leo,
I have installed procexp form sysinternals and I use the Windows Task-Manager frequently. However I am a little unsure about what exactly are the several columns concerning memory for the processes telling.
How can I determine the overall memory that a process consumes? Do I have to add colums together?
In procexp there is a Virtual Size colum that seems not to correspond to any colum in taskmanager. It shows very large values. And the worst: Nowhere on the net could I find a detailed explanation for both programs.
Can you help?
Memory Management is so complex these days, thereâs no simple answer anymore to âhow much memory is it usingâ.
In process explorer I use âWorking Setâ as a measure of how much physical memory the process is currently using, and âVirtual Sizeâ the total amount of memory that the process is using, both real and virtual.
I hoping if you could tell me how to eliminate any hindering/ unnecessary processes from starting? thanks, Kishon Monteith
Hi,
I donât like the idea of running as Administrator, so I have an âordinaryâ account that I normally use. Thatâs a member of the âPower Usersâ group. But I can only see my own processes on the Task Manager.
The âShow processes from all usersâ box is greyed out.
How can I set up my account to view all processes?
I AM STATE COMMANDER FOR THE DISABLED AMERICAN VETERANS.BEING NON PROFIT AND ALL OF US VOLUNTEERS MAKES IT DIFFICULT GETTING HELP FOR OUR COMPUTER..I WOULD LIKE TO KNOW IF I WOULD HAVE ANY PRBLEM OR IF AANY WOULD OCCUR IF I STOPPED ALL PROCESSES RUNNING ON MY TASK MGR.THERE ARE ROUGHLY 73 PROCESSES RUNNING AND MY COMPUTER IS VERY VERY SLOW..I WOULD APPRECIATE YOUR HELP
No â stopping all processes will crash your machine, as some of them are requied. I would follow the instructions in the article and related articles to attempt to identify what each process is, and whether or not you need it before just killing things.

I currently run windows xp on my desktop. I have 1 primary user accnt (administrative level) and 3 secondary user acnts (limited/guest level). I use the adminstrative acnt 95% of the time. My computer is slow so iâm trying to optimize memory by elminating some start-up programs and certain processes, however, when I run âmsconfigâ and make my changes, I get an error message âAccess Denied. You may need to be logged on as an Administrative user to make the neccessary changesâ.. Iâve double and tripled checked that my primary user acnt is an âadminstrative levelâ and that i was attempting to make the changes while logged on to this acnt.. any suggestions on how to fix ?

WHAT PROGRAMâS DO I NEED TO RUN IN TASK MANAGER,,I RUNING XP PRO
I can see what is runningâŠbut seeing it isnât helping me at all. My âVirtual Memoryâ seems to max out. I was gonna up it, but itâs at 1000 already..and on this puter, at least, thatâs the max, it says. I can tell what is running, but I donât know what to do with them. For instance, it has âIEâ ⊠in TWO places with very, very high numbers. I wish I knew what to do for this. I get soooo much âgrindingâ sounds when I just want to open ONE screen. Does anyone know how to help me?
I have windows XP.
ThanksâŠ

Very good quick reference, thank you.
Hi â for the past week, something starts running after midnight and it causes the blue âscreen of deathâ â is there a way of trying to find out what is starting up at that time?
10-Nov-2010
After I had a HD crash and replaced it I re-installed the OS. Iâm a gammer and I play BF2142 âa lotâ, or did so to say. Now when I play after a few minâs the screen jumps around and the whole thing stagers worce then a drunk.
Iâve ran just about every spyware and virious program, reg repair and any other thing I can think of and nothing showes up. If I stop or pause the game everything seems to return to normal. Iâm now useing Norton Internet anti-virious and have tried everything I can think of to locate whats going on but as soon as I enter the game Norton seems to stop logging the processes. As soon as I pause the game everything returns to normal. Issue is that it runs great for about 8 minâs and then goes to itâs knees for about 4 minâs then it repeats itself. At other times I get a message that says program not responding and then Iâm asked if I want to close it or wait. sooner or later it respondes. On the internet some IPâs seem to take forever to load or I get a âNo linkâ message. Any Ideas? Iâm running Quad AMD 64âs at 2.8 ghz, Vista 64-sp2 fully updated. I have 8 gig of mem and plenty of video etc. This thing ran really fast before no matter what.
Hi there! I agree with another commenter. I can find out whatâs running, but the file does not give you enough information to determine WHAT IT IS, and exactly what itâs doing. I ask because my grand-daughter has just discovered the Internet, and since she has been using my computer it has, all of a sudden, slowed down. My computer is a Dell, only 13 months old, and I keep it cleaned, inside and out. Any suggestions? Thanks in advance
