There are many guides on line dealing with regaining access to a system
Use any Windows bootable disk, enter the repair, command line.
In c:\windows\system32\
Rename utilman.exe utilman.bak
Copy cmd.exe utilman.exe

Allow system to boot from hard drive.
At the login scree, hit the ease access, this will bring up a command window running with system level privileges
Net user you could either add a new administrative user, or change the password of the existing one.

Optiplex came with CD, to reset to factory default insert the OS cd, boot from it and wipe.

i inherited the pc -not the cd

Try Pogo Stick on a bootable USB key to reset the password

1. Restart your computer
2. While the computer restarts, press F8 to open the Advanced Boot Options menu
 If the Advanced Boot Options menu does not open, wait for the Windows logon screen to appear. Then restart your computer and try again
3. Select Repair My Computer using the Arrow keys and press Enter to open the Windows Recovery Environment
4. On the first System Recovery Options window, click Next to select the default option
5. Check if you can login with Administrator User (most of times no password is set for it).
6. On the Systems Recovery Options window, click Dell Backup and Recovery
7. In the Restore System window, select the backup file that you want to use to restore your system from the drop-down menu and click Next

Dell may have a recovery partition, boot the system using other bootable media including Windows 10 using mediacreation to setup a bootable USB and see if that is the case? Try as you turn on bootup, hit f10/f8 to see if the utility partition/tool comes up that avails you with an option to reset the system to factory default.

790 is likely out of warrantee, but using the service tag, you can check the warrantee status on Dell's site.

You could try and  purchase the Dell Windows 7 recovery CD ....
Try the guide I provided thou it will get you access I to the system, it will not provide you with an option to reset the system to factory default unless there is a recovery partition to which you can trigger the system to reset.
Dr. KlahnPrincipal Software EngineerCommented:
First check the System Service Tag at support.dell.com.  Enter the Service Tag number, at the next page select System Configuration from the menu at left.  Click Components below the Original Configuration tab.  Look to see what operating system originally shipped with the box; it should be W7 Professional if you want to reinstall W7.  (Dell dropped all support for other versions of W7)

By way of example, for an Optiplex 780 "421-2350 : Windows 7 Professional Downgrade to XP Professional SP3, Media, Optiplex, English" would be appropriate.  This indicates that W7 Pro can be reinstalled from Dell media without a COA and that you can legally download the Dell W7 recovery DVD image at

There is a site dedicated specifically to reinstalling Windows 7 on Dell systems.  Best to read it, as there are numerous traps along the way when reinstalling W7.

James BunchSystems EngineerCommented:
Dell also has a Recovery OS tool, link below, that you can use the service tag and download an ISO file of the factory windows and drivers that was deployed with the machine. You can use this as a "Nuke" option if you need too but will lose all data on the hard drive, which if you inherited it like you stated it shouldn't matter.

One important piece you need to make sure you have before using this option is to get the Windows key, typically on the sticker on a computer that has whatever version of Windows it was deployed with. Without that key, you can only install a trial version of Windows and will have to acquire one within 30 day if you want to keep the system up to date.

arnoldCommented:
Do you have a bootable USB with Windows 7,10,8 to boot the system and access the filesystem via a repair console?
You have to see whether you have a recovery partition,
Try escape during the system startup to access the utilit menu

If there is a recovery partition, directing the system to boot from it will reset the system to factory default....
nobusAuthor Commented:
arnold you said "At the login scree, hit the ease access, this will bring up a command window running with system level privileges"
i don't get that, only a screen with 6 choices for selecting narrator, increase, letterype, contrast etc..

Dr Klahn i see w7P32/64 - take it that means PRO, but what about 32/64  ?
and using the download software - what do i select: extract or install ?  https://www.dell.com/support/home/us/en/4/drivers/osiso/recoverytool/WT64A
is that tool bootavble or not?
arnoldCommented:
You have to do the things I advised, boot the system using another Windows boot media, get into repair console, rename utilman.exe to utilman.bak
Copy cmd.exe to utilman.exe
All of these are in the c:\windows\system32 path

Once the above change is done, when you boot the system from the harddrive, hitting the ease access will bring up the command window where you can use net user to add a new user and the add this user to the local administrators group met logalgeoup administrators /add username

Once you do that in the command window, you can return to the login screen and enter the credentials for the newly created user.

If you are OS reinstall will clear..
If you are not, you would need to repeat the earlier process to copy bak the utilman.bak to utilman.exe ...
arnoldCommented:
The drivers do not. Care which version of Windows 7. They apply to Windows 7 32/64 home, ultimate, pro, business etc.
nobusAuthor Commented:
arnold - i have a recovery partition - verified
but it is hidden - so i can't boot from it (that's what i want to do all the time)
i don't believe you need to be able to boot into windows for restting the software - that would just be silly - no?
and i don't understand your last post  - or it is simply wrong
nobusAuthor Commented:
anyone knows a method for facttory restore this pc so it starts from the recovery partition ?
this is what i get when i boot to safe mode> repair your PC
5if you know a way to get past it - that's also fine !
nobusAuthor Commented:
arnold, you posted:
Net user you could either add a new administrative user, or change the password of the existing one.
can you postan example of how to edit the password, or add a new user as admin ?
arnoldCommented:
net user /add newusername *
you will be prompted to provide a password for this user, unless you provide a password instead of the asterisk (*). This by default will be a standard user.
net localgroup administrators /add newusername
this will add the administrators group to the newusername's membership, i.e. make newusername a member of the administrator's group (builtin/local system)
login with newusername and password entered will grant you access onto the system and you will be able to elevate rights to admin level when needed.

have not tried, depending on the setup, changing a password would invalidate/lockout access to some file ie. if efs or other security settings are there.

Using a new admin, may provide for the use of a tool that will when running on the system identify what the other local user's password is.
there are no guarantees that the password would be identified, but it offers an opportunity to try which the changing of the password on the account will definately prevent/eliminate/

i added a new user and administrator
however, when booted, i only see this
lhow can i login to the new user??
arnoldCommented:
Hit ease access,
After you add, you need not reboot, the user

Hit ctrl-alt-delete to bring up old login option and enter username/password.
nobusAuthor Commented:
arnold - hitting CTRL+Alt+ del does nothing  ? ?
arnoldCommented:
after you add the user, run
net user, does the new user appear in the list?
then run the below
net localgroup administrators
does the new user appear in the list?

the system may have something else setup, that clears the user?

you could use net user
then
net user <one of the listed usernames> *
and create a new password for the account...
then see if you can login with that account and the new password.
nobusAuthor Commented:
here's what i get :  
ni created the users ikke and norbert
below it says that the task finished with 1 or more errors
but you see it in the administraters list

butt how do i login ? on norbert?
arnoldCommented:
net localgroup administrators

Are you able to login with either Ike or norbert

if you reboot the system after the addition and on the display you do not have a listing of all four?
Dr. KlahnPrincipal Software EngineerCommented:
Side note:  You probably should enable Administrator just in case you need an untouched, known-working priv account at some time in the future.

https://www.petri.com/enable-the-windows-7-administrator-account
arnoldCommented:
in reference to Dr.Klahn suggestion

net user administrator /active
will enable the account, but without a password, the account will only be accessible/usable under safe mode bootup.

Boot the system in safe mode, and see if the two accounts you added are there and functional.
try running the net user ikke /Active and the same for norbert just in the event the creation of the account automatically came up as disabled......
nobusAuthor Commented:
but how do i login ? on norbert? is the command
net localgroup administrators norbert passwrd    ?
btw - you may notice that the account to which  i don't have the password - is not shown in that list DK-COATINGS/LIES
arnoldCommented:
The display of the button is the name of the user, it can be different than the username

It displays two users, and you have two users Ikke and Norbert

Create a somenewuser  literally. Set a password, add this user into the administrators group and see what the result is.
nobusAuthor Commented:
so you mean in the above blue login pic - just select other user ?
when i do that i get     "at the moment  there are no contact servers available to process your login request"
arnoldCommented:
Create a new user that is not listed there.
Set its password
Add the user to the local administartors group.
Login using this user.
nobusAuthor Commented:
how will that help?  it is exactly what i've been doing ?
arnoldCommented:
you may have been creating a user that already existed. creating a specifically unique user to see whether the system has a software that on reboot kicks out users from groups,
when you add a user, you should be able to hit ctrl-alt-del (possibly hit delete twice while the two other buttons are depressed in order to get the old style login prompt where you can type in a username and password.)

as long as you can loginto start+U, or go through start+R utilman.exe you can bring up the command window running with system rights, where you can add the user to the administrators, group.   yous hould be able to login following the addition/creation of a user. without the need to reboot the system.

try when you are at the login screen and use the ease access, in the command line run
diskpart
list disk
select disk 0
list partition
list volume

if there are more than one disk,

Lets see if you have three partiions
100MB or so for the boot sector/uefi
most of the space for C:\
2-10GB for the recovery

you have to gain access into the system, without regaining access, getting the restore media from Dell is your ..
nobusAuthor Commented:
i already have the restore media ready made
here the partitions:
pp
but tell me how this helps me??
arnoldCommented:
If you have restore media, why are you not booting from the media, and wiping the drive and installing?

Accessing the system is only needed if you need to pull data off, or attach the drive to another system.

Looks strange, the partitioning looks as though it is an XP not Windows 10.


List volume which partition is the c:\ ?
nobusAuthor Commented:
why ?  ver y simple -  because i want to learn how to do it, in case i get one where it has to be done - not for data or anything
arnoldCommented:
The information I provided is to regain access to your system in a situation where the administrator password, or other password is forgotten or lost or locked because of a worm/virus......

The restore to factory relies on the system manufacturer and whether they provide a recovery partition. In some cases, during hitting F9, F11 gets the system to boot up into the Manufacturer utility that provides for a factory reset provided the recovery partition is present and has not been altered by a user who overwrote the manufacturer data with their own system image backup. Had a situation such as this, where the user used the recovery partition to store the current image which by iteself is not an issue, the issue is the person elected to delete the manufacturer provided image. The options when performing the backup was not complete meaning the image was not bootable.  Some use ctrl+F9 or F11 to get into the recovery......

The dell recovery and backup tool, is usefull but still relies on the existence of the recovery partition.

Were you able to gain access to the system? From my understanding of your posts, you have not. Creating users, etc. did not seem to have gotten you onto the system in a capacity where you could try the recovery option if available.

In windows 8/10 the F8 includes an option to restore the system to .... but would still require the recovery partition onto which the system will boot and follow the BootPE/WindowsPE image and reset the system to the factory image or the image present there if it works......

Dell at times includes a recovery partition,
nobusAuthor Commented:
i have the dell recovery ready - that's not the point
i want to try to access the system first - it has NOTHING to do with recovery or data
i just want to know HOW to get past the login
arnoldCommented:
What happens when you make the change as I suggested with utilman.exe.
on boot, you create a new user, and grant that user administrators rights.
what happens after that?
using alt-ctrl+del(twice) do

try net user <newuser> /active just in the event the user gets created disabled

The computer could have a restriction that prevents creation of new users that leads to the user account being disabled/deleted on reboot.....

Based on your image, the computer appears to be a member of an AD domain.

1) are you able to gain access to the system as a user of any level?
2) if you are, and you elevate the user's right ...
nobusAuthor Commented:
>>  what happens after that?  using alt-ctrl+del(twice) do  ==>> as i said - nothing at all
1) - no
2) - i can create an admin level - so i can't elevate it (i can also delete it

strange thing is the NORMAL, inaccessible user is NOT displayed with net user
arnoldCommented:
if you are able to access the system even with a standard user, you can use the utilman.exe (cmd.exe which runs with system level rights) to extend either this user the right to elevate or when elevating enter the created user with admin rights and password

First thing is first gain access to the system by whatever means you have.
once you are logged into the system, your control is limited to this system only, you can not piggy back to reach other systems in the environment.
nobusAuthor Commented:
why do you say that first paragraph?? iposted that i DO NOT have access anyway
or do i miss something there?
arnoldCommented:
My guidance to use the utilman.exe is to establish a local login that you can use to gain access to the system. You keep saying that you are creating a user, but it does not show up on the login screen. I asked whether this is/was a domain based computer to which I do not know whether you answered.

If you want to reset the system to factory default and if you do not need to pull data, why not use the recovery media you have to reinstall the system.

Perhaps I am missing what the end goal you are after.  In a prior comment, if a system recovery partition exists on this drive, using the ctrl+F9 or F11 right after the system is turned on might be all that you need.

The issue if this is a domain joined system, it will enforce its rules ........
It may have software from the Domain that shields its from being accessed.
nobusAuthor Commented:
i guess it is a domain computer - but i don't know for sure
i'll post my previous post again :

i have the dell recovery ready - that's not the point  - and i'll do that when i have exhausted other options
i want to try to access the system first - it has NOTHING to do with recovery or data
i just want to know HOW to get past the login
nobusAuthor Commented:
we're at a standstill it seems
while you could not give a solution, i'm happy with what i learned
arnoldCommented:
The point it is unclear what it is you are trying to achieve other than the end goal is to do a factory reset (either from within the OS if such an option exists on the system, or through a recovery console, or by booting the system from a recovery media)

You should set forth the criteria of the situation as the starting point.

i.e. my computer rebooted, and now I am unable to login, I did not have a password on my account, now it asks me for one.
or I forgot the administrative account password and I need it to install an application I need. This is a stand alone computer.
nobusAuthor Commented:
you should NOT be co,ncerned about my goal - i have posted it several times now -what is unclear?
in the Original question - all what you ask is posted - i suppose you skipped it, after reading the title
arnoldCommented:
I did not miss it, initially I addressed your no password. Then I addressed your restore to factory default.

I could ask the exact same question as you posted.
One post addressed the regaining access
One post addressed trying to invoke the manufacturer recovery option if exists.
And finally, having the recovery media on-hand you can restore the system to factory default, excluding recovery partition, especially if you delete.
nobusAuthor Commented:
but why adress the recovery - since i said i have it ready ?  keeps cluttering the thread with nonuseable comments
arnoldCommented:
Could you try to get into the recovery console using ctrl+F9 or ctrl+F11?
ctrl+F8 , F8 safe mode will not get into the recovery.
nobusAuthor Commented:
ctrl+F9 gets me to startup manager , with the only selection windows 7
ctrl+F11 windows error repair, with options safe boot, command prompt
