Windows 7: Locked myself out of administrator level - help!

Locked myself out of administrator level - help!

Hi all,

My problem occured when I modified my only administrator user account to auto-logon via 'netplwiz' (I also added a full name account to the account as well).

Finished changing this, then I realise I'm now been demoted to a Guest account, and stuck at this level!

I can not activate administrator for any playing I can do so far.

Any ideas without a reinstall (I'm on a system without a CD/DVD drive)

It will work...........................

EDIT: I may have jumped the gun..........didn't read it clearly.

I've got the NTPasswd working fine & booting on USB.
I can promote Guest login to Admin, but I can not promote my own login "Craig" to Admin. Craig <> Guest I suppose.
I removed the password from Craig and tried again, still no luck.

Have you tried logging in as the Global Administrator? ::
Go to Start/All Programs and right click the command prompt.
Type Control UserPasswords2.
Click Advanced.
Click Advanced again.
Select Users.
Select Administrator and untick the the box “Administrator is disabled”
Now log out and login as Administrator.

If you find, because of a “lower” edition, or level, of Windows 7, you cannot open the window above, do it this way:
Shut down the computer for a cold boot. Tap the "F8" key as you are booting.
Select "Safe Mode with networking" from the boot menu.
Log into windows Vista with your personal account that holds the administrator access.
Open a command window (START--->RUN--->CMD.exe). At the command prompt type the following "net user administrator /active".

Log out and log back in as administrator.

hi davehc,
I tried all options you discussed, all came up administrator password required (with no window to type it LOL), on in the case of DOS window (safe mode) "Access is denied"

I'm going back into ntpasswd having another look!

On the second method, right click the Command Prompt and select "Run as Administrator", before proceeding.

After my previous message I found a fix, and now working at admin!!

My story goes... while I was still in safe mode, I tried switching between users, and found I had the choice of the guest account (not seen before, that had been promoted to admin with ntpasswd).
ANother strange issue, looking at users my orginal user name "craig" had disappeared, and I could not add again (windows error of "invalid characters"??).
So there a few issues on this side... and that's why it called beta I suppose LOL

thanks for your help.. & cheers

Locked out of administrator privileges
I am new to Windows 7 after having used XP for quite some time. For security reasons, I used XP with the "Administrator" account just for program installation/windows update and then used a second user account that was a "power user" (i.e., not an administrator). I tried to do the same with...
