Intro: T-Structables: How to Lock Your Computer
How many of you out their have had someone snoop around your computer while you were away? Well, even if this hasn't happened to you, you can't prevent this from happening without downloading or installing anything. In this instructable, I will show you how to securely lock your computer to prevent intrusions.
Step 1: Illusion Setup
Basically, to lock your computer, we will present any user who tries to access the computer with an illusion. We will make it look like the computer is fine, but nothing will be click-able. To do this, we must first take a snapshot of the screen.
Exit all open windows, and press the Print Screen (PrtSc) button on your keyboard. Now open up paint and press Ctrl+V on an empty canvas. Your screen shot will now pop-up! Save it to anywhere you like with any name.
Next, set the wallpaper to the picture file you just saved. You are now half-way there! Wasn't that easy?
Step 2: Removing the Interface
Now that your desktop looks like a normal interface, we have to take away the actual interface. This is actually quite simple.
First, open task manager. Now click the processes tab. Now scroll and find explorer.exe. End this process, and your computer will be locked and un-accessible. The user can still Ctrl+alt+delete to task manager, but from there, they won't know what to do; you will.
To bring the interface back, Open task manager and go to the applications tab and press the "New task..." button. In the box, type explorer.exe and press "ok". The interface will now re-load!
There are ways to prevent task-manager from opening, and instead, asking the user for a password. I am not permitted to share how to prevent Ctrl+alt+delete. If you wish to know how, message me.
Step 3: Finished!
I'm sure this is not the only way to lock your computer, but it is the way I do it. And if you don't like the way I do it, don't criticize me on the way I do it. Instead, share with me how you would do it, because I would love to hear how you would do it =)
So with your new knowledge, rig your computer or laptop correctly and prevent unwanted intrusions. Thank you for viewing!
