Am I obligated to break the computer, in compliance with my deceased husband's will, or is it permissible for me to use it for my children's educational needs, given that I previously broke the satellite receiver and the mobile phone, and I have another mobile phone and satellite receiver in the rented apartment?

This bequest must not be carried out and is impermissible, because it entails squandering respected wealth. These mentioned items are used for both permissible and forbidden purposes and have considerable value. After the death of the inheritor, they become the property of his heirs, and bequeathing their destruction harms them. A bequest that includes something forbidden must not be carried out. It can be forbidden if it harms the heirs, according to the hadith (definition): "Harm in a bequest is among the major sins." The computer must not be broken; rather, it must be used for the needs of the children.
