I remember beta testing Windows 95 when it was code-named Chicago. Back then, I was running MS DOS 6.22 and running Microsoft Windows for Workgroups 3.11. I also beta tested numerous versions of Windows 98 when it was codenamed Memphis, Windows 2000, Windows XP, which brings us to this century where I beta tested so many versions of Microsoft Windows Vista (or, Longhorn) that I can’t even recall. I watched as Microsoft scrambled to try to meet the security disaster that were plaguing Windows XP. Some of you may not recall, but Windows XP was such a disaster in terms of security that it was rare to find a computer running a default copy of Windows XP, without a ridiculous infestation of spyware of some kind.
Back in the DOS days, I rarely used Windows 3.11 for hardly anything. I would use DOS to copy files, defragment my computer, browse BBSs, send e-mails, write batch scripts, just about everything. In fact, even when I switched over to using Windows more often I would still go back to DOS to do simple copy commands because it was easier for me to just write out the commands longhand. I used a hex editor to check executables for viruses because I didn’t have any antivirus software at the time. I guess my point is that Microsoft has had more than enough time to make a working security model for Windows.
