Dude. Print screen, paste into paint, crop and save as jpg, upload. That's what the button is for.

you should simply use the "lock" button in windows next to the "shut down", "hibernate", "sleep" and "restart" buttons. why so much hassle.

I'm glade this program helped keep nosy people and anoying family from messing with your computer. On my laptop I use my micro sd card in its adaptor because its small and hidden/ easy to remove if needed.

It is a nice find, but it is not really computer security. It is basically just a way to lock your desktop which can be done by setting a password on a screensaver app. It is only going to keep people out of your pc if you are within sight of your pc.

is there a way to circumvent the protection if you lose the usb?
Reply 9 years ago on Introduction
yes set the program to not start at startup, then if you lose your key just open program and creat a new key( just to make sure delete the old key incase someone stole it). In the payed version you can un-cheek the task manager box then if you lose the key you can press control alt delete to open task manager and close the service
