Mk. so this trick only works with windows operating systems. DONT BE SCARED! Master recovery (at startup you press the button to interrupt the operating system loading such as the ESC button. You want to recover your system so F11 or something) will not restore your computer to its previous password.
It will remain the same. It will only recover what you deleted, uninstalled, and other dangerous changes to your computer. But here, I will guide you. If you have HP Support computer, select the center panel and go into command prompt. In the command prompt, type exactly:
cd C:\Windows\System32
copy cmd.exe cmd1.exe
rename sethc.exe sethc1.exe
rename cmd1.exe sethc.exe
exit
then click on all the cancels (this will restart your computer).
on a Normal Computer (that does not have HP Support), try the master recovery (follow same procedure until you get to a desktop and window) when it asks you about using system restore, click NO. When the error message appears, click on see details, scroll all the way down and click on the text document link (ending in .txt). The text document comes up. Click on File then Save As... Up pops another window. DO NOT SAVE YET! Browse to C:\ (or the letter of your main harddrive. you can always tell when it contains the folders with the names
program files, windows, and users) then click on windows then click on System32. Find cmd.exe (It looks like command prompt, all black with C:\ on it) then right click on it then select copy. Find sethc.exe (a blue ball that you see at the login screen that says accessibility tools) and rename it to something else like sethc1.exe. THE FILE EXTENTIONS ARE VERY IMPORTANT! Find your copy of cmd.exe (like cmd-copy.exe or cmd(2).exe) and rename it to sethc.exe, and click on cancel, and get out of there. You may realize that sethc.exe is triggered (even on the logon screen) by pressing the shift button many times in succession. So trigger sticky keys (that's the official name of sethc.exe) by shifting too much, and you get a command prompt instead. So type in the command prompt:
net user
And you get a list of all the users that are active on the computer. Pick yours. I will represent it with USERNAME here in my example:
net user "USERNAME" *
And it will reply:
Type a new password for USERNAME:
Confirm new password for USERNAME:
And you reset your password! See if you can log on now! If you can, great! now you need to go and really recover using master recovery because you don't want anybody else doing that on your computer and trolling you. Hope this helps
