Windows 10: No admin rights - deleted all admin in registry editor

My sister had a secondhand laptop which had another person as the admin account. I didn't know that she followed a youtube video on how to delete the admin account in the registry editor. Before doing that, she created another user and set is as admin. Unfortunately, while deleting the admin account folder in the registry editor under the SAM folder, she also deleted the one she created. Now, when she logged in using the original admin account, she can't do anything with the laptop except for google chrome which still works. She can't use the start button/menu, view files, install programs and format the disk. I also tried doing system restore but I can't create restore points. It just says that there is a machine error. The laptop doesn't read the bootable usb for windows reinstallation.


What can we do? If we take it to the repair center and reinstall windows, will it create a new admin even if the folders were deleted in the registry editor? Please drop some advice. Thank you so much!

admin rights keep disappearing!?!!

Hi guys,

I am actually having a problem at work that our IT department hasn't been able to figure out. I am supposed to be a member of the admin group. We are on a domain. The problem is that everytime I reboot the computer I loose my admin rights(no longer in the administrator group) and just become a normal user again. I have tried googling this and didn't get to many results.
I believe IT is just giving me local admin rights, not admin rights for the whole domain.

Any suggestions?

EDIT: It is on Windows XP Pro.

 

admin password?

You can reset the Admin Password using Windows XP repair; See Here for step by step.

Go Back Windows 7 - error - must delete admin account

HI

Again I appreciate your effort to assist - but sadly again this does not solve my situation

I have time left on my 30 days - the return to windows 7 option is working but stops at the point of getting ready telling me I have to delete the Admin account (I apparently created this as a part of the upgrade process)

None of the instructions given allow me to - I have deleted the account in the family & other users section

There is no option to delete the admin account (that I can see)

I was given these as alternative suggestions - but they don't work either

Method 2

Please go to the registry editor and do the following steps:

• Click +, to open run command. Type "regedit" and click enter.
• Create a back of the registry. Click on Hkey and go to the File Tab, press Export and save it to your desired your location.
• Go to the provided path HKey_LocalMachine\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList.
• In the profile list you will find a few SID's please find the one related to the deleted user account and delete it.

To know which sid is related to the User Account you wish to delete just go to a particular S-1-5series and on the right side look for ProfileImagePath, you will notice c:/users/User_Account_Name.

- when I highlight the account the delete button is greyed out

Method 3:

If you have enabled Built in admin account, please follow the steps below to disable Built in admin.

• Press Windows + X key.
• From the jump menu select Command Prompt (Admin).
• Type net user administrator /active:no and hit enter.
