This is Very Easy one + tricky one....... just Follow these steps!
what you need: Command Prompt and Task Manager.
what you do:
Open Cmd Prompt [Start>Run>cmd.exe]
Look at your clock (on yer desktop) and convert that time into 24 hour (for the 12 hour people). here is a simple chart
12:00 AM = 0:00
1:00 AM = 1:00
2:00 AM = 2:00
3:00 AM = 3:00
4:00 AM = 4:00
5:00 AM = 5:00
6:00 AM = 6:00
7:00 AM = 7:00
8:00 AM = 8:00
9:00 AM = 9:00
10:00 AM = 10:00
11:00 AM = 11:00
12:00 PM = 12:00
1:00 PM = 13:00
2:00 PM = 14:00
3:00 PM = 15:00
4:00 PM = 16:00
5:00 PM = 17:00
6:00 PM = 18:00
7:00 PM = 19:00
8:00 PM = 20:00
9:00 PM = 21:00
10:00 PM = 22:00
11:00 PM = 23:00
12:00 PM = 24:00
For Example: right now my time is 11:20 PM which is equivelant to 23:20
in cmd prompt type: at (your time (24h) + 1 minute) /interactive "cmd.exe" then hit enter
Saying my time is 23:20
I would type: at 23:21 /interactive "cmd.exe"
it will say a new job added with an id=1 or something to that extent, wait till that time, a new command prompt should open up, if not try again, increasing the time you type by 1.
in task manager find/kill explorer.exe in the process's, your gui will disappear
close the command prompt you have written in, leaving the new cmd prompt (that was run at the specified time) open.
the cmd prompt open should be pointing to: [Homedrive]WINDOWSSystem32 (Replace homedrive with a letter ie C, now type: 'CD ..' (minus the two ' )
The command prompt should now be pointed to: [Homedrive]WINDOWS (Replace homedrive with a letter ie C, Now type: explorer.exe this will re-open explorer under the system account, click start and look at the username.
if at school, you can now >>>>> add/remove/edit admin passwords, add/remove/edit admin accounts, change groups<<<< >>>> whatever you desire<<<<< (Will not work with network based groups).
