access denied on the C: drive due to the destruction of user name accidentally safety on the properties of the c: drive

By chance, I deleted all the names of users and groups in the security properties of the C: drive

shortly after that I tried to access the C: drive and discovered that access was limited to it.

I tried to use the Security Editor, but I'm also locked down because I don't have permission, even if I'm running the active user in administration settings.

It is very annoying because I have most of my computer files on the C: drive, and I am unable to run application shortcuts from the desktop as the directory of all the shortcuts applicaions lead on the C: drive, which is is not accessible.

So far, I tried to disabled UAC and other services concerning the name of user and groups, but also "access denied"...

I'm not able to run CMD and RUN.exe of normal mode, but I can not in safe mode with command prompt,

I therefore believe that any possible solution must be done under mode safe mode with CMD.

I also tried to follow the instructions, but I had no success because the instructions was for someone with a vista and some of the directories mentioned files there is not applicatible for Windows 7.

http://forums.techguy.org/Windows-Vista/831578-cant-regain-adminstrator-access.html (post #10)

I heard that formatting the drive can bring back the factory settings and the previous user, but put names in form is not an option for me, I never run'ed a backup of the C: drive or its contents, thus losing all that data would be catastrophic for my financial and emotional state.

Is their way of bringing user names I have both in the security properties of the C: drive?

Hi Xerovoid,

You can try the steps below.

Step 1

A. Click Start > computer

B. right-click on the C: drive, click Properties.

C. click on the Security tab

D. click the Advanced button > owner > Edit

E. make sure the replace the owner of subcontainers and objects box ischecked

F. click apply, Ok

G. wait until it changes ownership. (may take a while)

H. check if the problem persists.

Step 2

If the above does not help you solve the problem then try the system restore on your computer.

    Windows Update forum is one of the three forums that doesn't have different forums for different versions of Windows (Internet Explorer and the game are the others).  With this in mind, we ask that you postat LEAST the following information.  If you don't know how to find some of the information and then post what you can and let us know that you need help to find information.

    Minimum information to validate:
    Version of Windows and Service pack level. (Windows XP Home Edition, SP3; Vista Home Premium, SP1; Windows 7 Ultimate, etc...)
    Post also if you use 32-bit or the 64 bit version of Windows.

    Update the number of the last update installed before any problem.  If you do not know the number of update, then give the date that the update has been installed.  The number of updates update failed.

    Error code updates failed or if you think an update caused a blue screen, give the blue screen error codes.

    Other information to validate:
    Measures already taken to correct the problem and the results of the measures.

    If the question is never happened before with other updates.

    A few other useful parts are:
    What program antivirus you use, if it is up-to-date, and there has never been any other installed antivirus program.
    If your version of Windows has been upgraded from a previous version or if it came with (or clean installed with) the version you are currently using.

  • I get an error, access denied to the C:\Users\myuser\AppData\Local\Temp

    Original title: access denied to the C:\Users\myuser\AppData\Local\Temp

    Hello

    I have a problem with the Windows 7 C:\Users\myuser\AppData\Local\Temp temp folder. Sort randomly, I lose access to this folder, in the sense that if I open a cmd terminal and I try to cd to that folder, it gives an access denied error (at least that I start cmd as administrator). I noticed in the list of permissions on this folder does not appear the SYSTEM. I read somewhere that this is the problem, so I added back, and then it worked. Unfortunately it disappears every day the list of permissions, and I have to put in place every day which is annoying. Do you know what could cause this problem? How can I see which changes these permissions?
    Thank you

    Hi Razvan,

    Thanks for posting your query in Microsoft Community

    According the information you have provided, I understand that you found error access denied when using certain commands to the command prompt. I will certainly help you in this matter.

    1. have you logged as administrator?

    2. do you have an antivirus software installed?

    Some commands that you run at a command prompt, you need the administrative privileges for the good functioning of Windows.

    See the link.

  • "Access denied" error when updating driver

    My monitor is an HP w2207h (screen 22 "HD flat).  I get "Access denied" error when you try to manually update the driver by using Device Manager.  When I use the installation of HP or Windows Update utility, I just got a message that an error has occurred.  I've recently updated my NVIDIA driver using windows update (VISTA 64).  On reboot, I get a message asking me to select a driver for my HP flat screen monitor.  When I try to install the driver by using the auto option or by downloading manually from HP, I get an "Access denied" error message.  I am the administrator on the computer.  Can you help me solve this problem?

    It is alittle bit of a lenghty process, but it should help to solve the problem. Follow the steps in this KB http://support.microsoft.com/kb/315539 to show the devices 'hidden' in Device Manager. Browse the list of drivers installed for the graphics card and remove all drivers that are "grayed out" then uninstall the drivers for your monitor. Restart the system and try to install the driver at that time here.

    What can be produced is installed the drivers can interfere with the currently installed driver and this should allow the system to update the driver correctly.

  • Access denied on external hard drive.

    I have an external drive, which works perfectly well. But I've just updated from vista to W7, and now I can not access the disk from that specific computer. I get access denied. On the properties, all users have full access. And the funny part is on my other computer, with the exact same OS, the drive works perfectly. So, I expect that there is a setting that I didn't know.
    Is there someone with good ideas on how to solve this problem?

    Hi I tried your instructions below to restore all my administrator permissions full on my external hard drive.

    1. click on Start , click all programs , and click Accessories .
    2. right click on command prompt , and then click run as administrator .
    3. in administrator: command prompt window.
    4. type
    takeown /F (external drive letter) and press ENTER.
    5 type
    CACLS (external drive letter) /G Administrator: F and press enter

    After that I followed these steps, my computer Windows 7 says that the drive is not accessible.  I plugged it to my old XP computer, and it also says "access denied."  I have a huge amount of important files there and I need to restore access, but I can't find an answer for how to cancel the steps I followed.  Please tell me how to reverse the steps I did your earlier suggestion.

  • "ERROR: access denied"on the partition does not work no security and takeown tab.

    Hi assistants.

    It is my last resource to solve my problem, hope that someone can understand. Any help is appreciated.

    I'm unable to takeown to my hard drive using one of the following:

    • Run cmd as admin takeown /f l:
    • Log in as administrator, cmd, takeown /f l:
    • Takeown /f l,: run takeown in Safe Mode (with command line),
    It always returns "ERROR: access denied."

    In the beginning, I have removed all the user/group permissions via right click-> properties-> Security-> edit and he urged something on the legacy, so I followed this and removed everything. (Little I didn't know that it can't be undone...)

    Now when I right click on the drive and make appear the properties, there is no security tab and left click says access denied.

    Sorry, I'm just ideas. Here are the options I have for you:
    (a) see if you can do something when the machine with your repair CD Windows 7 starts in a Repair Mode command prompt.
    (b) save the file elsewhere, and then format the partition.
    (c) let me take a look at your machine (because it is four eyes see more than two).

    If you want to learn more about option c), send a note to pegasus_fnlATyahooDOtcom.

  • Access denied to the second disc

    My hard drive went wrong, so I bought two new albums: SSD for the OS and a few applications and a regular hard drive for data. I pulled the old drive, threw the new ones, reinstalled Windows on the SSD, and everything was good! I have created a few directories on the HHD, downloaded files in there and then I rebooted to finish a few things from Windows Update.

    When I logged in, I could not open the phonebook on the HHD containing my downloaded files. "D:\ is not accessible. Access is denied. "This has constantly produced with the second disc.

    Some info:

    • Windows 7 Pro 64-bit
    • C: drive is a NEW SSD drive with an operating system installed on it
    • D: drive is a NEW HHD for data
    • I connect with the user during the installation, I created. This user is in Admin group.
    • As far as I can tell, I have no problems with permissions on the SSD
    • A lot of people have this problem with the old disks after upgrade or reinstall - this is not the case here! These discs are new.

    I tried the things:

    • Granting of permissions/access my user group is part of the
    • Granting permissions/access directly to my user
    • Granting a group ownership of the directory my user is part of the
    • Granting ownership of the directory to my user
    • Do the foregoing to various combinations of input drive root, parent directories, etc.
    • Reformat the drive several times - this solves the problem for a while, but he returned after a few reboots

    Granting permissions or take ownership usually results in an "access denied" message I can perform these functions if I log in safe mode.

    Does anyone have any ideas or suggestions? I am completely frustrated and confused at this point. I have full access rights and have even files, but still receive "access denied" errors

    I reinstalled the latest Intel storage drivers and the problem seems to be resolved.

  • Access denied to the d ' training

    Hi I know this has been posted often enough here, but I already tried this:

    Here you go:
    1 restart in Safe Mode.
    2 log in under an administrator account.
    3. click on start
    4. type the three letters cmd and press ENTER.
    5. type the following commands and press ENTER after each:
    takeown /f D:\/a r d y
    ICACLS D:\/t/c/accorder administrators: F System: F everyone: F
    (Answer "Yes" when prompted "Are you sure?")

    during the execution of these actions I get access denied errors config.msi and system volume information.

    I can't download files on drive d or install some programms on this, but I can copy files to it very well and open the files of it. I really don't want to format this drive, if it can be avoided.

    Hello

    I see that you are getting the error message access denied.

    Quick questions:

    1. Installation of operating system?
    2. Is d: drive your recovery disk?

    You can click with the right button on the "run cmd.exe as Administrator" and then repeat the steps you mentioned in your post.

    Note:

    The system volume information may still get access denied, which is normal. It is not recommended to change it.
