    Hello osamanaiem56,

    Thanks for posting on the Microsoft answers Forum.

    I recommend that you look at the solutions of the following missions:

    If this does not help then try the following suggestion:
    Right click on command prompt and run as administrator. Type the following command:
    WinMgmt /verifyrepository
    If the system returns "referential WMI is not consistent", run this command:
    WinMgmt /salvagerepository
    The first time you run this operation fails. (It will assign orders to stop services leading to failure. "This may take a few minutes for the services to stop). Run the command again. You may in fact need to run 3 times before finally runs and ends on its own.
    Reboot your system.

    If please reply back and let us know if it helped to solve your problem or if you still need help.

    Hi 1pinktink,

    Welcome to Microsoft answers forums!

    a. What is the exact error message that you receive?

    b. don't you make changes to the computer before this problem?

    c. what anti-virus program you installed on the computer?

    This problem may occur if there is a conflict between windows defender and the security software installed on the computer.

    I suggest you try the following steps:

    Step 1: Disable security software, follow the steps mentioned below

    Note: Activate security software back once the test is completed.

    Step 2: The System File Checker (SFC) utility allows administrators to perform an analysis of all protected resources to make sure they are the correct version. Whether SFC should find all incorrect versions in one of these protected resources, SFC will be replaced by the correct versions.

    You can still run a SFC scan on the windows vista computer. To run a scan suite SFC as follows:

    a. Click Start, in the start search bar type cmd, right-click on the command prompt icon in the box programs and then click Run as administrator.

    b. at the command prompt type sfc/scannow , and then press ENTER.

    Step 3: Install the latest updates for windows defender

    To check updates in Windows Defender, follow these steps:

    1. start Windows Defender if it is not already open. To do this, click Start, click programs, and then click Windows Defender.

    2 search for new definitions. To do this, click search for updates now

  • Windows Explorer has stopped working vista 64-bit

    This is a random error that continues to be. I wonder if I want to seek a solution, when I do, it seeks a minute then quits or restart the program, when I do closes. It's random, seems to happen with windows internal programs, it happens more with I click, right happens again and again, but I'm going to work if there is more then a why to open a program like: go to control panel and double click on Device Manager, I get Windows Explorer has stopped working, but I can't get to the system hardware tab Device Manager and it opens fine.  I can do a restore and I don't know that I don't have a virus or spyware on my computer. I can't say at this point when it started, cause I just thought it was a freak thing.  Maybe something to do with the UAC.  There must be an easy fix for this. Please help, going nuts about it.


    The problem is probably AVG which has caused a lot of problems lately for 8.x and 9.x.

    Frankly, I would delete it. Download but do not install the replacements until AFTER you remove AVG
    and restarted.

    For ALL - download - SAVE - go to where you put it-right-click on Reboot - RUN AS ADMIN - when you have finished

    AVG removal tool


    Here's what I use and recommend:

    Avast and Prevx proved extremely reliable and compatible with everything I threw at them.
    Microsoft Security Essentials and Prevx have also proven very reliable and compatible.

    Avast Home free - stop any shields is not necessary except away from Standard, Web and network is working.

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (Sometimes you have to temporarily turn off with the little icon to the left of the + bottom right of IE)

    Avast - stop home - free - all shields you do no need except leave Standard, Web and network running.
    (Double-click the blue icon - details look OK. - upper left Shields - those that you do not cancel).

    Or use Microsoft Security Essentials - free

    Prevx works well alongside MSE or Avast

    Prevx - Home - small, fast, exceptional CLOUD free protection, working with other security programs. It comes
    a scan only, VERY EFFICIENT, if it finds something to come back here or use Google to see how to remove.   <-->  <-->

    PCmag - Prevx - Editor's choice, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever suspect malware, and that would be unusual with
    Avast and Prevx running except a low occasional (not much), updated cookie and then run it as
    a scanner. I have a lot of scanners and they never find anything of note that I started to use this configuration.

    I hope this helps.

    This error message comes just out of nowhere I do not install anything or make updates when this issue was raised. I tried to restart the computer, but it did not help.

    I checked for viruses, but none came.

    In addition, I used the command line to find the problem and found a few corrupted files, it has been unable to remedy.

    Details of SFC are:

    I don't know what to do from here.

    I don't want to reinstall all of Vista. In addition, Vista is PREINSTALLED on my computer.

  • Windows Explorer has stopped working error - I can't right click a folder on the desktop.

    This is my brother's computer, and they do not arrive in his account, only mine.  I have administrator rights, but it seems not to matter. This problem occurs only occasionally.  For example, I can right click on this text, copy it, then paste it.  However, if I go to the desktop and try right click on a folder to rename it, I get the error.  The error indicates that Windows Explorer has stopped working, when it says that it restarts, then the Office updates really quick. None of what I found in the forums have worked again this is why I started a new thread.  I think it might be a problem with the registry, then someone can please help me quickly find a solution?

    Note: I can not run as administrator command prompt because I can't right click, so I can't run sfc/scannow.

    We are volunteers here for the most part.

    It's a shame that we don't know anything about the distressed system but it was MS Answers owners have chosen to implement this community - do not ask basic system information when a new question is asked that make problems a lot time and frustrating.

    But now they way they choose to turn things around here.

    Maybe this will help you with your system of unspecified of brand and model with the release of unspecified Windows and Service Pack and unspecified install antivirus/antimalware:

    When the Windows Explorer (not Internet Explorer) is wrong (especially when right click), begin to suspect third-party add-ons explore extension.  You can also see some errors of NAT (DEP, Data Execution Prevention).  DEP errors are reported when XP will be threatened by a program and Windows stops threatening program.  Windows should never feel threatened by the Explorer Windows (or Internet Explorer) to less that some add-on is the cause.

    Those who would be the Explorer extensions that do not belong to Microsoft.  This means that extensions that you have added.  Solution Explorer extensions are generally well and installation of certain applications will install extensions from Explorer solutions for you, give you a choice and sometimes they can be added without your knowledge when you install the new software.

    Solution Explorer extensions are sometimes added as a new right-click option, you see on folders and files (like the scan of this file, open that file, play this song).

    If there is something in particular that you do during exploration that you know will be the cause of the problem, which will help focus on the problem and the help that you suddenly know, when you have found and corrected.

    If you can get there when you want it, make an adjustment and then there is no message the next time you don't do anything, you do, you have found and corrected.

    First of all you need a way to see what modules explore you have installed now and a way to turn them off (not uninstall them) so you can understand that we are at the origin of the problem.  You can have a lot of extensions not installed Microsoft don't even know you about.

    Download ShellExView here to see what Explorer extensions you have loaded:

    ShellExView does not install anything on your computer, simply of runs and displays.

    After you launch ShellExView (shexview.exe double click) and acknowledge the security warning, adjust the column widths, so you can see everything clearly.  Under Options, choose "Mark non-Microsoft Extensions" and extensions not Microsoft will be pink, clear, but on some systems, which is a difficult color to see, so click on display.
    Choose the columns and move up or move down in the column of Microsoft is narrower upwards (Mount) so you can see on your screen without having to scroll left and right.

    Click on the header of column called Microsoft (it can be the way out of the right side of the screen) to sort the display (by clicking on the column heading in Microsoft) so all non Microsoft extensions are at the top and easy to see.  They will say 'No' and be marked in pink because they are not extensions Microsoft, something like this:

    Non-Microsoft extensions would be things you have added (non-Microsoft) and are what you should be suspect.

    If you see extensions which do not have anything that is listed under Description, Version, product name, company or have special names that looks like they might be letters and numbers just randomly, you might want to look at these first.

    You can also Google the name of a suspect add-on and see if there is any success on the Explorer accidents or mistakes DEP and what other people have done about it.

    You can Google something like:

    Windows Explorer crash

    You must complete your suspect on behalf of adds on.

    See what kind of search results hits you get and are looking for solutions or situations that sound like yours.

    I'm not a defender of trial and error, but I can't think of another way to do...

    Right click and disable the non Microsoft extensions one at a time (or maybe in small groups of 3-5), keep a list, so you can enable them again later if you wish. The result of the change is immediate and no reboot is necessary.  Test your failure condition (right click).  If the Explorer starts to act normally, you'll know that some extension you just disabled in this group of 3-5 is the culprit, then you can start to enable them one by one until the Explorer fails again.

    If you recognize all the extensions that have been added or recently downloaded, start with these first.

    Disabling the extension does not uninstall the extension - it is just disabled.  You can always enable it later, so keep track of things by writing them down.

    Disable them one at a time or in small groups (to make things go faster) until your right click does not generate an error, then restart and test again to be sure.   You have disabled the last extension would be suspicious.

    You can also disable all non-Microsoft extensions, restart, test your fault condition and allow them one at a time until you find the one that generates the failure condition.

    If you have a large number of extensions, you can disable them is small groups, 3-5 at a time instead of 1 at a time until your system starts to behave.

    When it does not, you will know that the problem is one of the extensions of this small group and you can enable members of the Group at a time until the problem returns, then the problem is with the last extension that you enabled.

    The hope is that you will find extensions that is causing the problem and then you can figure out what on this subject - either uninstall it or see if you can get an update of the author of the extension of their web page.

    I have not your problem, but I can when you toggle extensions, the extension is immediately disabled, so disable an extension does not seem to require a restart, but if you think that you have found the problem, I reboot and repeat the test in any case to be sure the problem disappeared.

    If you post your non-Microsoft extensions list, maybe someone will recognize it as a potential problem.

    If you find the offending extension that's the problem, please let us know what it is that I can add to my list!

  • HP20: Windows Explorer has stopped working, followed by windows explore restarts

    Hello everyone, a few days my computer began to behave strangely. When you try to download some pictures using Chrome, windows Explorer has crashed, and a pop-up will appear showing the message: "Windows Explorer has stopped working". A few seconds after that, the entire desktop up-to-date and another window poped by displaying "Windows Explorer restarts... ».

    The cycle of two windows appearing repeatedly. I restarted the computer as soon as it shows the office, the same thing happens again, to infinity.

    I was able to restart the computer by using the security mode, it works just fine. I've disabled most of the software at startup, except 360 total security anti virus. It has not solved the problem.

    Does anyone have a solution for this? Thank you very much for any help!


    Hi old_geekster, I tried what you said and it did not work. However, I then found the original source of microsoft where you got this info from, and they mention here on a corrupted video driver as a source as possible. That was the problem in my case: radeon tried to update earlier this week, but I was in a hurry and it did not properly. I tried again and it worked now!

    Thnaks for your help, even if not exactly what I needed, it solved my problem!

  • "Windows Explorer has stopped working" if I open Control Panel

    Guys, could someone help me please?

    When I open the Control Panel, it says "Windows Explorer has stopped working" and then it restarts Windows Explorer. When I right click on any folder it says "recording of the UI language is not valid" 5 times and for a split second, it says "Corrupted registry" then it works. But I am unable to use the control panel.

    I have Windows Vista home premium and Norton Antivirus.

    Can someone help me please?


    The error message says something about corrupt registry.
    So, it seems that this issue would be related to incorrect or damaged registry entries.

    If the registry is damaged, your operating system will not work as it should and can feel such or similar problems.

    I m using the CCLeaner to clean the registry and other system files.
    It s a free tool and you should try it.

    If this does not work and if you notice the same question so I would recommend reinstalling the OS using the Toshiba recovery disc.
    In most cases this will help you fix this registry

    My M70 lost (I will follow soon!). Windows XP has stopped working, registry problems. I finished by using the Toshiba Recovery disk and reformat the hard disk. Said again there is some registry problems and crashing.

    One had similar problems?


    Hi Phil,

    If your laptop is always report registry errors after having re-installed the operating system from the recovery disc, then it is likely that your hard drive has errors. The Windows XP registry is composed of several files (or urticaria), and the installation process will always be located in the same area of the hard drive.

    I think that norton or mcafee may have been preinstalled as trial versions, but I've never actually used them. Unfortunately I can't use the windows Explorer, so I can't check if they are still there.

    We will cover all the possibilities.

    1. download each of the tools for deletion below, save it to your desktop:

    Norton Removal Tool:
