New Administrator Mishap

Did you get the admin account established before you deleted the default one?

You can always use the "hidden" one if you need to. Hope this helps.

Built-in Administrator Account - Enable or Disable

I don't know a way around the wizards running when you open programs without looking at it (and thinking some more) but you should be able to create another admin account and get everything working again. Use the hidden one if you have to....then disable it when you have everything working the way you want. I did about the same thing one time on XP. I just had some inconvenience for a few days.

Hi,

If you have somehow managed to delete your last/only administrator account it will not be possible to activate the Hidden administrator account, as this requires administrator rights to action.

However, as a fail safe windows should automatically activate the hidden administrator account in these circumstances, but only in Safe Mode.

You could try booting into safe mode, (tap F8 after the initial POST but before windows starts to boot), hopefully this will give you access to safe maode as administrator which will allow you to create anothor administrator account for day to day use.

The problem with the Net user options is that they require administrator rights to run. If they could be run as a standard user then anyone could use them to change the admin passwords or to enable the administrator, thus removing any security in the system.

as a last resort fix you could try this disk ....

Offline NT Password & Registry Editor

You will need to download the ISO and burn this to disk using a suitable ISO burning program. This disk will allow you to rebuild your users

   Warning

this is a Linux live disk that you should not use if you are at all unsure of what you are doing. read and print out the instructions and have them to hand during use as inproper use of this software will make you system unusable

That NT Password & registry editor DOES work. Just to confirm Barman's recommendation. I had to use it on Vista on a computer I was fixing, It's not for the faint of heart but it works.
