But something should not be stopped to be used when the company that produced
it stopped supporting it. It is useless to throw away old things because the
company that produced them decided to do so regardless of people's needs.
It is the case with Windows 2000, MS-DOS, Windows XP, Visual Basic 6.0 (for
which there are still books sold and it is still used), Qbasic (which is still
used by some people, I myself used it ), Windows 98 (still used in some Internet
Cafes here as they do not want to buy any more software).
Sometimes it is useful to revive "dead" or unsupported software.
