How to disconnect my computer if I can’t remember domain login credentials?

You don’t really need the domain account credentials to remove your computer from a domain. The authentication provided by your local administrator user should be enough. Please use those when your system asks for passwords while applying the methods above.

Can I convert the domain account to a local account?

Microsoft used to provide the Windows Easy Transfer tool, which you could use to convert domain accounts to local ones and vice versa. However, Windows 10+ no longer include this feature. You’ll have to use a third-party app if you want to convert your account.

But, it is possible to copy files and user registry settings to a new local account. Then, deleting your domain user will provide a similar result to converting the account. Follow the steps below to execute this method:

  1. Create a local account.
  2. Then, restart your PC and log in as a different local administrator.
  3. Open Run and enter systempropertiesadvanced.
  4. Look for User Profiles and click on the Settings button under it.
  5. Click on the domain user and select Copy To.
  6. Choose Browse and navigate to the profile of the new local user. Then, click Ok.
  7. Now, select Change. Then, click on Advanced.
  8. Click Find Now to see a list of users. Select the new user and click Ok. 
  9. Click Ok on all windows to close them while applying the changes.

Is it possible to remove the Domain group policy from my system?

Domain group policies can force many restrictions on your computer. However, it is possible to remove such restrictions using the Registry Editor. Here’s how you can do so:

  1. Enter regedit on Run.
  2. Navigate to the following keys and delete them:
    • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft
    • Computer\HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft
    • Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy Objects
    • Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies

Warning: Manipulating registry entries can break your computer. So we recommend making a system restore point before deleting those keys.
