Does the child constantly press the CD-ROM open button? Knocks on the keyboard, sending abracadabra to your blog? Closes the program window, should you just turn away?
Freeware
Toddler Keys can: disable the Power button;
lock the door of the CD-ROM drive;
block the keyboard separately (you can continue to use the mouse, fighting off the tenacious children's fingers :));
or block the entire computer.
IMPORTANT remark: the program does not seem to know that there are other keyboard layouts, passwords are not entered in the Russian layout, and it is impossible to switch it. Therefore, I recommend using numbers as passwords.
