Forgotten your Windows 7 password?
It is every Windows users nightmare: one day you try to log in and every attempt is denied. Whether you have forgotten your password or it has been changed or you need to get in and don't have the password, there are some tricks to break in.
Using no software or tools:
The first method to try is a bit of a Windows hack.
Take the battery out if you have a laptop and plug in the mains
Start windows and then whilst it is starting up, pull the power out to force an automatic startup repair on the next boot
When it restarts you will see the Windows Error Recovery
If you see a screen which gives you the safe boot options, just keep trying and eventually it will give you the above screen
Select Launch Startup Repair (recommended)
Windows will then load files and begin the startup repair service
Wait for a few minutes, sometimes it can take a while, for a box to pop up saying "Do you want to restore your computer using System Restore?" and then click Cancel
Wait for another 5 to 10 minutes for a pop up to appear saying "Startup Repair cannot repair this computer automatically"
Click on View problem details
Select the final .txt link, usually addressed "X:\windows\system32\en-US\erofflps.txt"
Then, on notepad (viewing the .txt), go to File > Open
Go to C:\Windows\System32
Change Files of type: to All Files
Find sethc.exe amongst the files
Rename it to sethc1
Then find cmd
Right click on cmd and select copy, then rename cmd-copy to sethc
Close notepad and press cancel on Startup Repair to restart Windows
Let Windows start normally and wait until you see your user profile log on screen
Press shift 5 times quickly to open your renamed cmd.exe - now you can use the command prompt before logging on
In cmd, type net user to see a list of users
Choose your user and reset their password by typing net user USERNAME * (where USERNAME is the username taken from the list)
Type a new password for the user or just leave blank and press enter
