Specs: Windows 7
Feeling embarrassed.I was experimenting with
cracking my own password which worked with
only 3 digits. I then used a 9 digit password
and attempted another crack. I have now been
locked out of my own computer. How do I
regain control please? PS I have attempted to
load pressing F8 in safe mode, still no joy.
Feel a fool, sorry.

Ok, here is a rather crazy exploit that will work. First get yourself a Linux LIVE CD. (If you don't know how to get/burn one of those I wouldn't try this anyways). I would use something like Ubuntu that auto mounts your drives for you.
-Next, navigate (in linux) to your windows drive C:\Windows\System32
-find the file named sethc.exe and rename it to sethc.exe.old
-copy cmd.exe and rename the copy to sethc.exe
-reboot into windows
-when you get into the login screen press the shift key 5 times, and a command prompt window will show up that has admin access. you can now use this to change your password from the command prompt.

'lost password self inflicted'

sorry, I don't buy it, with the amount of laptop thefts today, I notice people go to all lengths to crack passwords.

If your quest is legit, good luck

So an easy way to change your password back Rogskill is to use the command:
net user username newpassword
also when you are done you probably want to go back into linux, delete sethc.exe and rename sethc.exe.old back to what it was so you no longer have a backdoor into your system ;)

Many thanks for your replies so far. I have managed to
produce the Command Prompt. I am still mystified however
as to exactly what to type into it? Any further ideas anyone

So close and yet so far as they say.

Many thanks Roger


I guess I can understand your point of view. Perhaps all I am
really guilty of' if anything is naivety, I did after all use my own
name and email address. I respect your point of view and ask
for any assistance that anyone can offer.

When you get a laptop that is second hand you are suppose to wipe it and reinstall Windows every thing else is hacking because (unless specified by previous owner or search warrant) you are NOT allowed to access their data.

Ok, that said, if you want to do things the right and legal way and you either have the systems disk that came with the laptop or went out and purchases a new Windows Systems disk, then all you have to do is run the systems disk and chose to delete the partition when it asks.


If you really want to hack the system then Google Hacking Windows. There are 1000 ways to do it. I can think of 3 easy ones right off the top of my head but can not say them because of forum policy.
