+====== Windows - Reset windows password from linux ======
+.  Put the livecd in the cd/dvd drive and boot your windows machine from the livecd.
+.  Once booted, open the terminal and check for tool named "chntpw".  If not there, you can install it using:
+<code bash>
+sudo apt-get install chntpw
+</code>
+.  After the tool is ready, mount the windows partition. Use "fdisk -lu" to check which partition should be mounted.  To mount /dev/sda1 (assuming your windows partition is on /dev/sda1), use below command:
+<code bash>
+sudo mount /dev/sda1 /mnt
+</code>
+.  Find the SAM file on the windows partition.  Usually it is located in Windows/System32/config.  Run the chntpw on the SAM file.
+<code bash>
+cd /mnt/Windows/System32/config
+</code>
+List all users in the SAM record.
+<code bash>
+chntpw -l SAM
+</code>
+Interactively edit the user's credentials.
+<code bash>
+chntpw -i SAM
+</code>
+.  Follow the wizard of chntpw and clear administrator or any user's password that you want to access.
+.  Save changes and restart machine.  You can access the windows without password for administrator and users that you have cleared their password.
+<WRAP info>
+Make sure you take out the livecd, otherwise the machine will boot into it instead of windows.
