Well I have done a few, Windows 3, Windows for workgroups 3.11, Windows 95, Windows 98, Windows 98SE, Windows XP, Windows 7 and now Windows 10.
Also a few Unix systems along the way during my military service.
My memory is a little sketchy prior to windows 3, but I also had an Amstrad PCW (Personal Computer Word processor) and an early PC with an Intel 8086 processor, twin 51/4" floppy disks, no HDD and a ridiculous amount of memory may have been as little as 128KB.
On my last trip in the military (early 1993) I went to Hong Kong for 30 days as part of a team replacing an old IBM 2900 main frame computer (large air-conditioned room) all the ancillary equipment data storage drives six of them each about the size of a washing machine.
All this was replaced with an HP 3000 desktop system and an external data server, in the room that the systems manager used to sit.
I bought a new motherboard, 8286 (or possibly 8386) CPU and some Memory chips (massively different to today) to upgrade my PC when I got home. Much cheaper in Hong Kong.
