In 2012 i had posted about Change Windows 7 password, Click Here to Read
So what about windows 8?
There is Easy of access menu on Login Screen, Why renaming sethc.exe with cmd.exe doesn’t work?
Because its metro style UI and microsoft has kept sethc.exe for normal UI and
it uses Utilman.exe for Easy of Access menu on Login Screen.
So Use same method used in Windows 7 and instead of sethc.exe use Utilman.exe
What Should I use for renaming this files?
Any other OS from which you should get access to drive containing Windows Directory
e.g. 1) Alongside installed or Bootable Pendrive Linux Distribution
You need to mount drive where target Windows is installed (generally C:)
2) Windows Installation Disk (CD/DVD/Pendrive)
In windows 8/7 installation disk go to repair and advance option and Command prompt
and simply press C: to jump to C drive and check using dir command if you are in correct drive
now you have access to target windows drive
1) Go to Windows/System32
2) Create backup of Utilman.exe as Utilman_backup.exe
on Linux : mv Utilman.exe Utilman_backup.exe
on Windows: move Utilman.exe Utilman_backup.exe
3) Copy cmd.exe as Utilman.exe
on Linux : cp cmd.exe Utilman.exe
on Windows: copy cmd.exe Utilman.exe
Now you are half done.
but don’t you think that we should probably restore target’s previous password when we are done? we don’t want he/she to get know that we actually had access.
but, we don’t know password, encryption algorithm and all.
Let’s backup whole password storage folder and restore it when we are done, right?
so where’s it?
1) Backup config folder
Linux: cp -r config config_backup
Windows: xcopy config config_backup
IMPORTANT: Don’t move anything from config folder
windows checks config folder before boot and will not start if finds some problem in config folder
Now Restart Computer and boot into Windows
and login screen click on small Easy of Access menu located at lower left corner
Wow… command prompt is open.
now use following command
net user bhushan *
Command Prompt will ask for new password. Enter and you are done.
use username you want to change password instead of bhushan, its my username.
I don’t know users on this computer?
go to C:/Users
this lists down users of current OS
Public is always there, don’t consider it.
3) Now type exit to exit command prompt or something else you are comfortable with to close it
4) Enter your new Password and Enjoy
5) Don’t forget you have to restore Previous password
Boot same as 1st step and just copy file from config_backup to config
To remove all trace. restore Utilman.exe and delete its backup.
