- Word and Excel have autosave options in Tools>Options. See the help if they are not self-explanatory. Or have a look at
- Access will save any change in it's database as soon as it's done. No problem there.
- Don't know about Powerpoint, but says it has also.

And no, things not saved are lost if the program quits. But you can set the Autosave option to 1 minute if you prefer so.

Hope this helps.
