Hi
Robert Hdez,
Perform the following workaround to enable the default administrator account and set the password.
Enable the Default admin account by running the following command:
1. Go to start and type cmd.exe
2. In the program pane right click on cmd.exe and choose run as administrator.
3. Type the following command in the command prompt:
net user administrator /active:yes
4. You should see a message that the command completed successfully. Log out, and you’ll now see the Administrator account as a choice.
Once you have enabled the default administrator account set windows password. Follow the articles below for help on that:

Hope it helps.
Thanks and Regards:
