I recently followed instructions to update software from Toshiba for my Satellite P70 A laptop running windows 10.  Their instructions were faulty and it caused a problem, now my laptop won't recognize the CD/DVD Rom drive because of "code 19" configuration info in registry incomplete or damaged????  I called Toshiba, they just want a lot of money and a promise to fix it.  I tried several fixes for the problem listed on the internet, none of which worked.  Any ideas where to go next?
