    Csrss.exe is running client/server subsystem and a necessary Windows process.

  Because the computer is not correctly behaving as expected, I suggest you run a virus scan to verify the infection.

  Method 1:
  

  Run a scan antivirus on your computer.

• I tried each posted end and can't do the stub.exe or the setup.exe to run. The Task Manager shows the file is running, but absolutely nothing happens.

  I used to have firefox installed. The last update ran for hours by saying he had applied. I uninstalled firefox, and now I can't install it again. I think I tried everything. Download the stub file or the configuration file, but they do not run. I tried to create a profile using the idea of % appdata %. Nothing happens. Need serious help.

  Before I posted my question, I did all this except that I do not restart after uninstalling firefox. However, I have restarted several times since. I don't let my computer started if I do not use it. Secondly, somehow, I must have deleted my profile. Following the instructions, I could not find.

  I don't care. I tried something different. I restored my computer to a point of restoration later in January. And now, I had an icon of firefox once the recovery is complete. However, he wouldn't. Said that he could not find XPCOM. I used the control panel to uninstall firefox. Didn't happen. But, I tried the full download of the page "Download firefox in your language". It worked, it worked! Yay!

  Thanks to you who responded to this specific question and to all those who have responded to similar questions. I think I've tried them all. Restoration has been the thing that has done the trick for me. Now, I'm better set a new restore since what I am entitled to firefox doing this response point. Thanks again.

• Window 7, I have 100 processes running using the Task Manager

  what I do with this mess and should not kapersky make up for it?

  What is it? If theyre not malware then Kaspersky will not do anything.

  Use something like ccleaner, go to tools / startup. Click at the bottom right. Copy and paste what happens here. Do the same for the Tools/uninstall

  So we can see what is installed and what is start-up

• My computer takes an exceptionally long time to open and close. I have to delete svchost.exe process system via the Task Manager to stop the system. Problem is recent.

  I recently used wireless net via Cisco router. However I don't know if the problem is with it.

  If you install the new software try uninstall and see if problem is resolved or not. Also try to restore back your software once before the problem happens. Try defragnment and disk performance checking, cleaning disc and scan your PC with antivirus or Microsoft Safety scanner online:

• Google Update is running in the Task Manager, even if I don't have Google chrome open

  Original title: Googleupdate.exe * 32

  Windows 7 HP 64 bit.  (sp1)

  Google Update is running in the Task Manager, although I have not Google chrome opened.  My pc is running slowly, my network is slow.  Its bad enough I can't install programs via a disc more (which didn't need internet connection or speed), but to have windows and other services that run in the background continuously, who do not have something productive and I cannot control drives me crazy.    I need to disable or stop the services, tasks, programs that run several times and are not necessary.  Some do not stop little matter what I do or restart even if disabled.   I ran antivirus, malware software software and nothing shows ever.

  As an administrator:

  I disabled (via the services)

  1 Google update service (gupdatem)

  2 Googe Update service (gupdate)

  But I still Googleupdate.exe * 32 running.   I check and these both are disabled.  So is there a service control for programs and services 86 bit 64-bit and 32-bit?  And how to get there?  Or is it in software?

  How to disable the GoogleUpdate.exe. service * 32?

  In dealing with this problem after installing or using a google application and service "Googleupdate.exe * 32" which is causing the problem, you can contact google for assistance.

• 29 Firefox fails to come out properly and continues to run in the Task Manager.

  It is a continuation of a thread found here:
  https://support.mozilla.org/en-US/questions/997448 by Compumind.

  I pointed out that I had the same experience, especially at the opening of the email links in Thunderbird. I reported also that forced me to go back to 28 FF.

  Moses responded by top wire and suggested:
  (1) download a fresh installer of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

  (2) the release of Firefox.

  (3) rename the folder

  C:\Program Files (x 86) \Mozilla Firefox

  TO

  C:\Program Files (x 86) \OldFirefox

  (4) run the installer you downloaded in the #1. It should automatically connect to your existing settings.

  I followed these instructions carefully but no joy. When installing 29 FF, not only refused to leave (using "exit") and continue to run in the Task Manager up until I killed him after the opening of links in Thunderbird, but I find that he refused to come out after a simple navigation and links.

  Moses had asked that I didn't answer in the original thread, so I re-post here.

  In my view, that there is a serious bug. With Firefox 28... no problem don't except a minor that I have indicated here:
  https://Bugzilla.Mozilla.org/show_bug.cgi?id=1002089

  Yet once I am obliged to 28 FF, although I miss the nice interface and security patches, I need to have a browser that works properly. My wife never even saw the Manager of the tasks before so that's the problem.

  In addition, "guesses" made with this post, the only other thing usual outside that I do, is to have a security policy about cookies (accept by default... I make exceptions for cookies I want to keep and have several that are "allow only for the session.") I also FF the value delete history of navigation at the exit, but that takes a fraction of a second.

  I look forward to when this matter can be addressed successfully and I am able to use 29 FF (and out properly... I can't wait for my wife to follow all of these instructions and it often close manually in the Manager of tasks... or what I want to do this.)

  Good luck for all Mozilla projects. Having installed 29 FF twice and then back return 28 twice, I'll wait and see how this plays out. Please don't send me the standard "start in safe mode", 'restart with disabled modules', 'reset Firefox' stuff (the last time that completely destroyed my browser). I don't think that is what is happening.

  Moses added that there is a problem with the e-mail notifications passing by, so take your time, friends.

  I think now (temporarily) this bug or problem has its roots in "history leaving Compensation."

  I made the leap after a few game with 29 PortableFirefox and reading the blog post linked here:

  [https://support.mozilla.org/en-US/que.../997918#answer-566755]

  .. .and installed 29 FF on my previous FF28 on my box. I unchecked the "clear history on exit" which was only to delete my history, not cookies or anything else, cor - el. My setting should not accept cookies unless I make an exception. Until the FF developers find a way to do this is functional, I'll just have to manually delete the history.

  Furthermore, John99, you want to maybe privacy.sanitize.sanitizeOnShutdown set to 'False', not 'true' If you want to stop the automatic deletion of the history at the exit (attempt).

  I've been running for about 6 hours. without experiencing the bug 'suspended '. So, I can live with that for now until this bug is fixed. It should be fixed... browsers are supposed to be able to do things like that.

  On the other hand, I could find things go wrong... but so far I'm not having a problem.

  I for several hours and will let you know later if things change.

  Kind regards

• is it possible to set the level of priority permanently running in the Task Manager?

  Hello!

  1. My question is anyway to change the level of priority at all times by a program running in the Task Manager?
  • For example; I am using a software called xpadder that is for players for the games which are rather old and do not support the for windows xbox controller so I want to change the priority level of this software in the Task Manager, as I don't have to change the priority level from the top on normal or high normal etc whenever I run...

  So a little help would be really grateful :)

  Windows does not support this setting, sorry.

• Iexplore.exe process still running in the Task Manager

  I was see multiple iexplore.exe processes in the Task Manager when I'm not in IE, so to trouble shoot it I uninstalled IE, run several different scans/squared (which found nothing) and iexplore.exe is still appear in the Task Manager. I guess that it is some sort of virus since I uninstalled IE and it is always showing to run. No idea how to do the trick of it? I am running XP.

  IF IE 8 was present in the control panel > add or remove programs, then when you have uninstalled it from there, you have restored the previous version of Internet Explorer, in other words, IE 7.

  The best way to confirm this is to start IE and then click Help > topic.

  There is malware that disguises itself as iexplore.exe.  If you see iexplore.exe or Iexplore.exe in msconfig or in the Task Manager after Windows startup, but you did manually start Internet Explorer, you probably don't have a problem.
  What antivirus applications you scan with?

  If you haven't already done so, I suggest to do the following:

  Run a scan virus online with the eSet online scanner (may require a download if you are using a version of Internet Explorer)

  Download, install, update and run MalwareBytes AntiMalware (free)

  Download, install, update and run SUPERAntiSpyware

  You can uninstall all the latter after their use, if you wish.

• I seem to have in dual processes that run in the Task Manager.

  In the Task Manager, I see the same process running several times.  Example: under user/Admin""(My name as) ","Local Service","Network Service"and"System"." "  These really duplicates and they slow down my system?

  Are they duplicates?  Perhaps.

  They slow down your computer?  Depends on what you're trying to do.  Anything that takes your resources take the pool available for other applications.  However, if you do not run low on resources (your CPU has a lot of horses for what is needed and you're not missing memory for most) - then it probably isn't as much of a downturn as just all of the resources actually get used.  You won't slow until that run out you of resources and try to open something else.

  If you worry about it?  N ° except if you have been compromised (you have a virus, worm, Trojan horse, malware any) and this is what is running - the system is as it should.  You are not running a single-user system - even if you are the only physical user.  Service accounts, etc. are there for the functionality of the machine as a whole.

  Windows XP...?

  I have some tips that might help you optimize this system...

  Search for malware:

  Download, install, execute, update and perform analyses complete system with the two following applications:

  • MalwareBytes (FREE)
  • SuperAntiSpyware (FREE)

  Remove anything they find. Reboot when necessary. (You can uninstall one or both when finished.)

  The less you have to run all the time, most things you want to run will perform:

  Use Autoruns to understand this all starts when your computer's / when you log in. Look for whatever it is you do not know usingGoogle (or ask here.) You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.

  You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory. This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

  Do a house cleaning and the dust of this hard drive:

  You can free up disk space (will also help get rid of the things that you do not use) through the following steps:

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.
  -Select TOOLS - Internet Options.
  -On the general tab in the section 'Temporary Internet files', follow these steps:
  -Click on 'Delete the Cookies' (click OK)
  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
  -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

• What is 'Quickactionbox' appliction? He is constantly provide in the list of applications that are running in the Task Manager on several occasions.

  

  Here you can see the problem. What is this thing?

  Hi Benjamin,

  Thanks for posting your query on the Microsoft Community.

  According to the description of the problem some application named QuickActionBox is running and showing in the Task Manager.

  If you think that this application is not known to you and you think that's not important, then you can uninstall it in the list of programs. But before you uninstall this application, I recommend to create a system restore point and try to uninstall the application so that if this application is important, then you can come back to this point again.

  To create restore point, you can see the article mentioned below.

  A restore point is a representation of a stored state of your computer's system files. You can use a restore point to restore system files from your computer to an earlier point in time. Restore points are created automatically by the restore of the system each week and when System Restore detects the beginning of a change to your computer, for example when you install a program or a driver.

  Create a restore point

  You can uninstall a program from your computer if you no longer use, or if you want to free up space on your hard drive. You can use the programs and features to uninstall programs or to change the configuration of the program by adding or removing certain options.

  Uninstall or change a program

  Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.

• Windows 8 does not not log on screen, all black dekstop, explorer.exe, disc missing from the Task Manager

  Hey. I am a newbie in this forum. And I really like to make my PC more 'me' even though my parents and brother told me that my PC did not differ from how difficult. But, I still like my PC... ^ ^
  But my PC encountered a problem in my birthday (March 8, ehehe just FYI). Its a terrible birthday gift: (...) Oh, there. Its all started when I accidentally install a skin pack or win 7 in my PC 8 victory. There is nothing wrong with installing proggress except a notification which inform on win 7 Starter has not installed correctly. :( Well, I ignored, first. But after I have it reboot, my dekstop went all black but it still can open the Task Manager. And then I try the system restore. It did not work properly. The only thing made worse. Somehow, my "(le seul compte dans mon PC) DELETED account." In fact, the log on screen consist only of the ease of access and power button with backgorund optomistic. Where are the data of the user, I mean a place where we inserted the password? XC its make me super bad mood. And after some restoration system with various restore points, I restarted my PC in safe mode successfully. Yippie, its worked perfectly in safe mode. I created a new account in safe mode. I thought that my problem more but no. and the bad news is that there is only one user account (a new one) in the journal on the screen! It'll be better I have the new account very well work, but it didn't! The dekstop always all black with no taskbar and it's the same problem as the first.
  I am not really confusing. What should I do? Should I remove a skin pack safe mode? or reinstall win 8 in PC COUNTER? Or do something that you already know the guy?
  Help me. I am so irritated by this problem. In any case, I want to ask one last thing, you prefer something after me or just think it was a charitable organization? Well, I just want to know. And I'll do my best to show my appreciation once you help me. I am so TROUBLED even if today is my birthday! I want a big anniversary with neither party. But its seems no big birthday. Please, help me. His will probably be my MOST BEAUTIFUL GIFT to a person who I know in internet. If you need something detailed about my problem, ask me. I need your response. :") SURE ME MY CRAZY MOM, IF SHE KNEW IF I AM WRONG IN MY PC AGAIN.

  Oh, there. The explorer.exe does not start in normal mode, but it works fine in safe mode. Also, I discovered that the disc is missing from the Task Manager. :) Help?

  Wish you a very happy birthday, Damaris.

  Of course, I can understand the situation you're in right now, and it's a shame. I will be happy to answer your query and try my best to offer my help as a gift for your birthday.

  Let me ask you;

  1. What happened when you tried the system restore?
  2. What was the last time that the computer worked well?
  3. What security software is installed on the computer?
  4. Remember to no particular change in the computer before the show?

  The issue may be due to any dispute of third party software, virus or any system or missing files / corruption. Let's try the methods below and check the status.

  Method 1: Since you are able to start the computer in safe mode without any mistake, I you suggest to start the computer in safe mode and then perform the clean boot to avoid software conflicts.

  Step 1: Start the computer in safe mode (as you are able to start the computer in safe mode with the steps you tried).

  Step 2: Perform the clean boot

  To help resolve the error and other messages, you can start Windows by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  Put your system to the clean boot state helps determine if third-party applications or startup items are causing the problem. You must follow the steps in the article mentioned below to perform a clean boot.

  How to perform a clean boot in Windows

  Note: see 'How do I reset the computer to start normally after a boot minimum troubleshooting' to reset the computer starts normally after troubleshooting.

  Method 2: Run Microsoft Safety Scanner

  The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

  Microsoft safety scanner

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  Note: Data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.

  Method 3: Run the tool File Checker system in case where any system files are missing or corrupted.

  System File Checker is a Windows utility that allows users to find corruptions in Windows system files and restore the damaged files.

  Enter in the right edge of the screen and then click on Search. Or, if you use a mouse, point to the corner bottom right of the screen, then click on Search. Type the command prompt in the Search box, right click invite, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click allow.

  At the command prompt, type the following command and press ENTER:

  sfc/scannow

  Note: Not close this command prompt window until the audit is 100% full. The results of the analysis will be posted when this process is completed.

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

• Firefox is running in the Task Manager, but only opens a window.

  I can't get Firefox to open a window. I tried firefox-p (Profile Manager) and firefox-safe (safe mode), but nothing works to open a window. I uninstalled and reinstalled, but that solves nothing. I haven't changed anything recently, so perhaps there is a update (?) Here's what happens:

  I try to start Firefox, and the Task Manager indicates that Firefox is running. It employs about 32 k of memory, but the window never opens.

  I click Firefox again. Manager tasks indicates 2 Firefox process now. The second is to use about 4 k of memory. Running Firefox repeatedly adds additional tasks to Firefox, each using about 4 k of memory.

  After about a minute, the additional tasks of Firefox (the 4 k ones) start closing 1 by 1. I am now down to only 2 Firefox process, using 32 k and 4 k of memory, respectively. As far as I know, these processes will last forever, until I have shut them down manually. If I run Firefox again without closing the current process, it creates another 4 k process, which finally closes itself. If I close all the processes manually, I can start over from scratch. Meanwhile, Firefox never opens a window, or give a clue showing that it is running, with the exception of the processes listed in the Manager tasks.

  bdemmon said

  I deleted the one in my USER folder without change. There are a couple more in various C:\Mozilla\Firefox\Profiles files, so I deleted those too, without change.

  It's a custom location. Normally, the profiles are under AppData\Roaming, I think you already know. There is a shortcut:

  %APPDATA%\Mozilla\Firefox\
  

  This folder must contain a profiles.ini file (.ini file extension may be hidden), which shows the names and paths to your profile folder (s). If you check in a text editor such as Notepad, this file contains sound data?

  If this started right after an update, it could be a problem with security software, put an end to the commissioning (rules of program control) or program files has been corrupted.

  You can check your firewall and other security software for program restrictions.

  To meet possible corrupt files, I suggest:

  Clean reinstall it

  We use this name, but it isn't about deleting your settings, this is to ensure that the program, files are clean (no incompatible or exotic code files). As described below, this process does not disrupt your existing settings. Don't uninstall NOT Firefox, that does not need.

  (A) download a fresh Installer for Firefox 43.0 https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

  (B) the release of Firefox (if any).

  (C) to rename the folder of the program as follows:

  (Windows 64-bit folder names)

  C:\Program Files (x86)\Mozilla Firefox
  

  TO

  C:\Program Files (x86)\OldFirefox
  

  (Windows 32-bit folder names)

  C:\Program Files\Mozilla Firefox
  

  TO

  C:\Program Files\OldFirefox
  

  (D) to run the installation program that you downloaded in step (A). It should automatically connect to your existing settings.

  A cleanly reinstalled Firefox starts up normally?

  Note: Some plugins can only exist in this OldFirefox file. If it is missing something essential, present in these files:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins

• Firefox won't work, even if current running in the Task Manager.

  We have about 5 users having Firefox refuses to open. In the task manager the firefox.exe is running. When we run as administrator, it works sometimes, but runs faster. We tried the ESR 38.2 Firefox and that worked for a day or two. I deleted their profiles and installed Firefox fresh with no Add-ons, even a day or two later, it opens. We turned off hardware acceleration, no change. The only thing I can think that I have not done is to clean the registry.

  5 users = all on the same PC?
  Or what with workstations and profiles on a server?

  Any type of configuration customized for when Installer Firefox?
