Windows 7 Home Premium - all user accounts have disappeared after the update of Windows...

My Windows 7 Desktop is really watered.  After a Windows automatic update, none of the user accounts appear in the login window.  Only a generic connection where you will need to enter the user and the password are displayed.  And when I enter the user name and password, I get a message that they are not valid.

Here are a few additional pieces of information:

1. I tried to restore to the point before the update, but it fails.  I get a message that there are missing files.

2. my other restore points I had before the update are no longer available.  I don't know what happened to them that they do not appear on the screen of restore points.

3. I can't log on to the computer at all, none of the accounts work.  I can get to a command prompt by using the repair disk, and I can see all the folders for the users.  So everything is intact.   Something must have happened to some system files and thus connect is not possible.

4. users appear in the list of profiles in the registry.

5. no windows service start because none of the users are no longer valid.

6. I tried sfc/scannow, but I get an error "already waiting.

7. I tried to add users on the command line using net and they are successful but even when they do not appear on the login screen and I can't manually type in these user accounts - I get the message that they are not valid.

I tried searching online and I'm still not able to connect to the computer.  It has been 2 days of downtime.  What happened to my old restore points?  And why doesn't my restore points created by the work of windows update?

I want to just restore from factory default, but I'm afraid I'll lose data in particular, all of the files currently sitting in the user folders.

Any advice would be much appreciated.

1. I tried to restore to the point before the update, but it fails.  I get a message that there are missing files.

-> Which files are missing? Can you give an example?

2. my other restore points I had before the update are no longer available.

-> This happens after the automatic updates.

5. no windows service start because none of the users are no longer valid.

-> How to tell you, because you were unable to connect?

7. I tried to add users on the command line using net and they are successful but even when they do not appear on the login screen and I can't manually type in these user accounts - I get the message that they are not valid.

->, I guess you have done this so that in the WRE (repair Windows environment). It is a ghost environment that disappears that you restart the system. Drive X: is a virtual, not a real disc.

I want to just restore from factory default, but I'm afraid I'll lose data in particular, all of the files currently sitting in the user folders.

-> Many people are unaware of the need for regular backups (for example, weekly) until they are suffering from a major disaster.

Suggestions

Going by your description, I suspect that your existing accounts are irreparable. They need to be rebuilt. User data appear to be safe.

Option 1. Use the console commands then in WRE to save all the files of the user on an external hard drive. A disk 2.5 "500 GB in a USB enclosure costs less than $60,00. After having tested the files on another machine, perform a destructive factory restore.

Option 2. Start the computer with a boot of Ubuntu CD, then its GUI allows to save files to the user. It takes time to burn such a CD, but the copy process is easier. When you're done, do a factory restore.

Option 3. A somewhat complex process allows you to create a new admin account, and then use this account to create new user accounts. You must then manually configure each of them (for example Outlook) and move their records of the old data to the new profile folders.

There is also a method to restore old files registry of a set of backup files are a few days old. In your case I wouldn't consider as it would create a disjoint system: the registry files refers to a set of files that have been largely modified by the update.

Post again if you need more detailed instructions for the option that you favor.

  • My office has just done a repair XP after a hardware change and now all user accounts have disappeared and he asks the administrator password when connecting!

    We have a unique system of Windows XP that run the software of engineering for certain calculations. All other systems running Windows 7, but what a XP system because it's the only thing that our calculations software runs on.

    CPU of the XP computer died on us and we had to replace the card mother and CPU. After the change of equipment, following Microsoft's OWN guide on the running an XP repair, we ran the system repair and got all the way to the login screen (no blue screen not as before repair). However, none of the accounts are there and he asks an administrators password. The system has NEVER had a password to our knowledge, it was built in the House, and all simply by clicking on the Administrative login asks for a password.

    What can we do? We needed this fix before today and wait for the repair of the system to do. Is it possible to enter the system to run the software? We tried the SafeMode (all forms) and they all will ask a password after Windows loading.

    It's so frustrating.

    (PS I have been building computers for nearly 15 years and have never had this happen)

    Thanks for the quick response. I looked into the system with a "start-up" program All original profiles seem to still be there. I don't know how to make them appear well. Can you direct me or tell me, how to make profiles see the place?

    The biggest problem, outdoors is not be able to sign more, is that the engineering calculation software is locked to this PC. It can be installed anywhere else without having to pay for a VERY new (I think that thousands of dollars) expensive key or a new version of the software.

    :(

    Yes, it's a problem.
    I believe you can use a UBCD4Win CD or Hiren Boot CD to locate and right click on the files you want to change. And then, if you properly in your repair facility, you change the attributes after you're done.
    Some guides are better than others. And here's one that I like:
    If necessary, hire a PC Tech. It's much cheaper than buying a license that is thousands of dollars!
  • I deleted several accounts of users, but after that I have restart the laptop all user accounts have been restored?

    I deleted several user accounts and need to restart to changesw can take effect, but after that I have to restart the laptop then all user accounts have been restored?

    Hi GhettoBoy,

    How do you delete user accounts? Is it just C:\Dosument and settings users or accounts under the control panel? If you don't want to keep all these account data, you can try to delete the profile of click Start-> settings-> Control Panel-> system-> Advanced-> user profile and select the profile and remove. Also check under 'User accounts' in the control panel to remove the names of users.

    I hope this helps.

    All my pictures have disappeared from the PSE Organizer 13 (after I've updated).  The files are all on the hard drive.  When I try and import them, said organizer that they are already in there and I cannot proceed.  When I select a keyword, get the message "NO MEDIA to DISPLAY.  I may be dense, but I find the search function of the Forum to be nearly useless, unless I just happen to enter the Exact name of a subject.

  • Vista Home Premium product key is not accepted after the repair, in which the computer was stripped of the same Windows software

    When my ET1161-07 came back from repair, it was so empty of software that even my "copy of Windows is not genuine", as it appears in the lower right. Due to this fact, I have no protection, either. I followed the instructions on the screen to type in the product key code that I found on the sticker on the casing of the machine (I had him bought at Costco, with preinstalled Vista Edition Home Premium, with no backup disk included), but the box would not accept even the next character to come at some point, to Midway. As a result, my window of Activation of Windows said I typed in the product key is not valid for activation, and I have to either buy a new online, or type a different product key or contact Dell to help solve this problem. Could you please help me with this? Fortunately, Istvan

    Hello

    First thing I would do is to take this computer to the place/person fixing it and demand that they fix it properly.

    We don't know where they got the Vista disk/license since they were installed.

    See you soon.

  • All my posts have disappeared from the Inbox.

    I realized there is a similar problem posted, but proposed solutions don't work here and the details here are different.

    All messages have disappeared from the Inbox. The sent box is fine, but deleted from the Inbox messages do not appear in the Recycle Bin.

    A search of the Inbox for messages of size > 0 allows me to see the messages and respond to them.
    If I move a message to another folder the moved message is invisible but believes it is search.

    Deleted messages are in the trash folder, but is not visible. A search in the trash finds them.

    Messages in the search boxes reuse (response, delete), but try to delete a selected message in the search box list has no effect.

    I found a solution. I can't take credit, but I tell you that I was almost embarrassed the simplicity of the solution and the problem.
    AT & T ConnectTech technician admitted that when I could left click and select the message in a tab, it was probable that nothing was clicked in the "select to display columns" in the top right of the CT. He clicks on a selection of articles and automatically that my messages appeared.

  • Some user icons have disappeared from the Office

    I use a Sony Vaio laptop running Vista business with Service Pack 2.

    Earlier today, most of the icons on my desktop disappeared. Who else is shortcuts in the folder C:\USERS\PUBLIC\DESKTOP.  Those who have disappeared are those of C:\USERS\MYNAME\DESKTOP.  When I look in this file by using Solution Explorer, all the files are still present. It's just you display the icon on the desktop that is missing.

    I am connected to my usual account that has administrator privileges.  Office properties are set to "Show desktop icons" and "snap to grid".

    Earlier today, I installed an update of AVG Internet Security and performed a full scan, but can't say for sure if the disappearance of the icons has coincided with this.

    It seems that the system is linking the visible office with the files in the Public folder, but not those in my personal file.

    I tried to restore the system to the earlier dates, but this did not restore desktop layout.

    Can anyone tell how to recover? Help will be very appreciated.

    Hi Jessen

    Thanks for your reply.

    In fact, it became obvious that the registry has been damaged.  I restored the registry to a previous state by using a backup, and that solved the problem.

    Thank you for your suggestions.

    Hello.

    After upgrading my OS Windows Anniersary Update 10 last week, my Beats Audio Control Panel disappeared. The audio is not yet, but the EQ settings I had set by beats do not seem effective. The IDT drivers seem to be installed and updated according to Device Manager.

    Thank you

    • Download the Audio driver from the Support page of the drivers of your computer for Windows 10

    Uninstall the driver from Device Manager > restart (or search the hardware changes) >

    If the driver is available in your file system, it will try to reinstall it at startup / login >

    Check the results

  • Lost all sound from my computer after the updates

    Driver Audio original was ahead AC 97 Audio for VIA (R) audio controller.  During updates, this changed to C-Media AC 97 Audio Device. Now I have no sound.  When I check in the properties for C-Media I get the message "this device cannot start [Code 10] any ideas how to get back my sound."  Thank you

    If you still get the wrong driver of WU on your sound card, hide the update.

    You go to the website of the manufacturer (sound card) and get drivers.

  • Is it possible to add the Win7 Home Premium 'Administrator' user account so that it can be selected during normal connection? I want to be able to log-in as Administrator without going the route of the F8, as in XP.

    I need to be able to log in as 'Administrator' to the normal screen log-in, ranging from the road to F8 vice. I can find no option for this, not even NET USER to the CMD window. If it is possible, perhaps via a registry change, I sure would appreciate the info. Thank you

    Good day to all! (I hope yours goes better mine has)

    When you try to access my internet postage program, I got a message that it was unable to initialize the printer.  When I checked the list of Printers and faxes in Control Panel... I find 4 all printers who WERE there yesterday... are now gone.

    (This excerpt shown below is extracted from the Microsoft support page & described EXACTLY my problem)

    • When you click Startand then click Printers and faxes to try to view your printers, no printers appear. This problem may occur even if you have a printer installed.
    • When you click Add a printer, or when you try to print, you may receive the following error message and cannot add a printer:
    "Operation could not be performed.  Printer Spooler service is not running.

    I tried several times to use "Fix - it" Microsoft online service, and he could not solve the problem.  I just kep saying me he couldn't solve the problem.  It is absolutely No. MS supports available unless you have at least $59.00 or more to pay for trying to help!  "Terminal" and valid on a model of disability very limnited former fighters from one month to the other... I could not certainly not even begin to afford no paid... help unfortunately.

    I am NOT computer saavy and I don't any idea as well WHERE to start... much less HOW to solve this problem!  Unless I can get this printer spooler service, or something else... running... I can't even begin to try to re - install a printer I have.
