Windows 7 has become my comments login and I'm locked out of admin

Hello

I've been running W7 Pro 64 bit very happy for two months. When I installed, I made a user account for me with admin privileges (I'm the only user on this machine). All of a sudden yesterday I noticed that I could not do some things and on investigation found that W7 has become my admin account a guest one. Same account name, icon, the user files, but no right! I did nothing to cause it, as far as I know, it just happened. I don't think it's a virus, Kaspersky certainly is not report anything.


I tried to boot from the DVD and by defining the built in Administrator account, but that the command window told me that the command executed successfully, when I restart I see no administrator account. Because I'm the only user I had previously defined netplwiz to connect automatically and I can't disarm that - I just get a window saying 'entry password administrator to run netplwiz' but there is no password box, probably because that there is no administrator account on the system.


I seem to be completely locked out from changes to the admin of my system. First thing I will do when I get the machine working again, is to create an alternative admin account to use if it never happens again, but for now, I'm completely stuffed.


Can someone help, please?


Thanks in advance for your suggestions.

UPDATE: I booted in safe mode with command prompt and run lusrmgr.msc to view accounts. Administrator account is here, just can't see on login screens. I thought that the administrator password should be blank (or perhaps the same one that I put in place with my initial admin-level account), so I tried shift-right-click netplwiz and selecting run as another user, and then typing in Administrator and white as well as a selection of passwords possible. No joy. It does not accept any combination of names of users and passwords.

So, how to use the administrator account?

Aaaaaargh!

I have fixed my problem on Windows 7 guest user.  The problem is after I added the computer successfully in my area, I decided to change the name of the computer. So I changed the name and the past of the domain to the working group. After rebooting I connected under the no original domain account, I created, but it was no longer a member of the administrator group and has been labeled as guest user account type.  I had not enabled the administrator account.

The solution: press F8 at startup for Advanced Startup Options.  Select the option 'Safe Mode with command prompt'.  I was given the opportunity to log on as an administrator, and I did.

I entered my orders, first to change the admin password then command to activate the administrator account:

"password net user administrator"-password the password to use.  (Password must meet complexity requirements)

"net user administrator / Active: Yes.

Computer restarted and I is presented with the option to connect as administrator.  Connected and managed to create a new account and add to the domain.

    If you encounter any problems with your external hard drive, this could be the problem.

    Well, don't know how it happened, but it works.

    Last night I went on the Web site of WD and downloaded

    1 EssentialEliteFirmwareUpdaterv1.032_1.0.7.4
    2 WDSmartWare_Software_Updater_For_Windows_1_0_12

    After I did it, I unplugged all of my other drives and I tried everything again with the missing disk, but it still does not.

    This morning, I reconnected all of my readers, and he started to read the missing disk.

    The version of the driver file is now

  • Windows 7 has lost all my settings and started looking for XP

    I have a new laptop with Windows 7 (64-bit). I'm about to install the software, I need for work and customize the settings. Everything worked up to now, when happened the following.

    -J' installed software (nothing special, for example (from a reliable source) existing communication software)

    -J' restarted the computer

    -All my settings for the taskbar and toolbar are lost (they disappear). The button (which is instead of the XP Start button) effectively changed to start button (looks like the XP Start button). The translucent window headers changed to those not translucent (as I'm used to XP). The bar of tasks/toolbar settings won't save any more (even if I register, they go back to an earlier version)

    How can I go back to 'Windows 7' and get my settings? What could have caused this strange behavior?

    I did this before on my own just see if I liked better. I did not so I went back to the Windows 7 look. In your case, there are a few different scenarios that can cause this.

    1. your theme has changed without your consent. -You can fix this with a right-click on your desktop and go to personalize . Change your theme to one that you have registered or by using the Windows 7 default labeled "Windows 7" theme. From there, you can simply add your images to customize your wallpaper.

    2. your Visual effect have been replaced by 'adjust for best results' .

    Open the menu 'Start' and right-click on computer . Go to Properties .

    Near the top-right corner of this window, you should see "advanced system settings" , click on it.

    Click the Advanced tab. Under performance , click settings .

    From here (depending on your graphics card), choose either ' let Windows choose what is best for my computer ' or ' Adjust to improve the appearance '.»» Click OK .

    3. Finally your graphics card driver.<->

    Is not as likely to happen by simply installing a program, but it's not of the unheard. Windows 7 will come back to that look older if somewhat your driver is corrupted and windows is still trying to allow you to use your computer. If you uninstall or damage your driver (ex installed a new graphics card) your computer can use graphics embedded gives you the possibility to use some of the nicer features of Windows 7 like the transparency and Aero Peek.

    Again, this is not as often, but if the other 2 suggestions above do not alleviate your problems try to reinstall your graphics card driver.

    http://support.AMD.com/us/gpudownload/pages/index.aspx-> for ATI Radeon

    http://www.nvidia.com/download/index5.aspx?lang=en-us-> for Nvidia

    If you are not sure of this graphic card you have click on your Start Menu , go to the search box and press Device Manager type enter. Click the arrow next to display adapters .

    A drop down menu should appear showing you graphics card. Go to one of the sites above to update or restore your drivers.

  • My Windows XP has problems with shlwapi.dll

    My Windows XP has problems with shlwapi.dll and there are plenty of sites to download, but they all want money, why don't misrosoft not has an answer for this problem. When I try to update to internet explorer 6 to explore 8 then the error always pops up saying: you have a problem with shlawpi.dll and he can not continue... Very very frustrating.

    In general, it is not a good idea to download dll files.   See, for example, http://pcsupport.about.com/od/findtheproblem/qt/dll-download.htm

    If you explain more in detail what your problem is, including providing the full text of the error without paraphrase, it is likely that someone in the appropriate Microsoft Answers forum will be able to help.

    Because it seems that your problem is related to Internet Explorer, you are more likely to receive help if you post in the forum Internet Explorer, where there are already many threads dealing with issues of shlwapi.dll on IE: http://answers.microsoft.com/en-us/Search/Search?SearchTerm=shlwapi&CurrentScope.ForumName=ie&CurrentScope.Filter=&askingquestion=false

    If you look through some of these threads, you can find the answer to your question without further delay.  If not (or if you just want to watch), do not forget to include not only the text of the error message, but also the version of Windows XP, you have (Home, Pro, Media Center) and its service pack (start > run > winver > OK).

    And, based on this thread - with what seems to be your exact problem - also include responses to the following questions (there no answer, certainly because the OP has NOT provided to the request for information):

    1. what application or anti-virus security suite is installed and is your current subscription?  What anti-spyware (other than Defender) applications?  What third-party firewall (if applicable)?

    2. do you have a free trial Norton, or a test of free McAfee [a] come preinstalled on the computer when you bought it? (No matter if you have never used or activated).

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager
    http://www.Vistax64.com/tutorials/193584-Device-Manager-install-driver.html

    If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
    Updates, that leaves about Windows updates but it will not install the drivers that will be generally
    older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
    get new manually if you wish.

    Refer to these discussions because many more excellent advice however don't forget to check your antivirus
