We had a computer in my 6th grade class and it had 3.1 on it...I remember going over there every day and having to close a couple hundred windows...in-which I would actually use it for something...(paint) only to have it die normally...but other than that is was my first computer to use
BTW I was a student in 6th at their age as everyone else...The teacher had no clue even how to turn the thing on...so I spent most of my time during recess messing with it and became proficient fast...so after that it somewhat became my "pet" in the classroom
There have been many Microsoft OS "Product Families".
DOS went through a ton of revisions from 1.0 all the way up to 6.22.
Windows versions 1 and 2 were just silly shells on top of DOS.
Windows 286 and 386 began a new family. The familiar entries in that family are 3.0, 3.1, and WFW 3.11 (Windows For Workgroups).
Windows 95, 98, 98SE, and Millennium are another family.
Prior to WFW3.11, MS had been working with IBM on the OS/2 project. There are various iterations of OS/2 with Microsoft branding that you might find floating around. But eventually half the technology from OS/2 made its way into Win95, and the other half into Windows NT...
Windows NT went through revisions: 3.1, 3.5, 3.51, 4.0 (which has had 6 Service Packs).
Windows 2000 is in essence NT 5.0, and XP is in essence 5.1. (Much as we love it, it's just an incremental improvement from 2000!)
Vista is NT 6.0, totally new kernel. Windows 7 is... yeah I'd really call it 6.1, but the marketing types make these decisions now, so it's 7!
I could get deeper, into where the kernels came from and what was introduced when, but... there's no point really.
It's staggering do to economy, not due to businesses abandoning Windows for other OS.Most software and hardware used by businesses is not yet obsolete and fine for their needs.The extra spending to upgrade from XP to W7 is not cost efficient at this time.Businesses will eventually upgrade due to advances in hardware/software that XP will not be compatible with, that is if they want to improve efficiency and keep a competitive edge.
I think it really depends on the size of the company and what market they are in. For large enterprises security is the driving force. XP was behind Vista and far behind W7. Smaller companies with lower threat and resources will continue to "leave well enough alone" but enterprises will end up spending more by not upgrading.
