Computers, etc

1. Why does'nt anyone check installations ...

When software tells me do you want to make a backup? I click No and continue I don't expect to see a message box that tells me:

"Now backing up"

2....or tasksheets?

Tell students to "do task XX". Only to find it dont work, never has worked and unlikely to work in future....

3. Why do we need sooooo many usernames and passwords?????
