Last Friday, I tried to help a guy who had inherited a 486 DX/2-66 running Windows 95 (on 12 MB RAM!). The scenario was that a lot of important documents had been deleted from the computer sometime between the previous and current owner. Thanks to undelete (is that commonly available in DOS around version 6-7?), I managed to bring back a bunch of documents, but none that matched what we were looking for.
However, within less than 15 minutes of working in Windows 95, I managed to bring up several unrecoverable blue screens of death. I had forgotten how crash prone it is.
