How to Lock PC temporarily when Someone enter wrong password

Hi Friends !!!
Today I'm going to show you "How to Lock PC temporarily when Someone enter wrong password".  Most of us saved our Important data and files on our computer. If we away from our PC, somebody may try to login into our system by guessing the password.


To avoid this situation we can lock our PC temporarily by using "Windows Security Settings". By using this option, our PC will lock automatically if someone entered wrong password more than 3 times. This will make hard to guess the password to the particular person. If the person entered more than 3 wrong passwords, PC may get lock for next 30 Minutes.



How to do this


Click on Start button
Type Local Security Policy in Search programs and files box.
Now Click on "Local Security Policy"

From left window pane Expand Account Policies
Then Double click on Account Lockout Policy 
After that Double click on Account Lockout threshold

Now a new window will appear. 

In that window give the value after how many invalid password login attempts you want to lock your PC.

Now click on Apply.
