My primary laptop has Windows 10 on it, and my shared desktop (which is actually a laptop being used as a desktop) has Windows 7 Professional on it. I still use both, but I would say I use my laptop a bit more now.
Mines where:

CPM (just a bit to play)
DOS 6.0 + Windows 3.0
DOS 6.22 + Windows 3.11 (my first "main" computer)
Windows 95 OSR2
Windows 98 SE (excellent for a gaming computer for the time)
Windows XP (THE best OS I know)
Windows 7 (pre-installed with my then new notebook)
Windows 2008 R2 (my current one)
Linux Ubuntu (toyed with a VM to see how is it)
Windows 8 DP (just a few tries to decide I do NOT want it)
React OS 0.31 (I would replace Windows entirely with it if it were more stable and faster)

My first computing was on Fortran 4 on a TDC-12 Computer while I was in college during 1976-1984. I used to carry a large box of punch cards for the college project. During that time I used Casio programmable calculator also.

Then Basic on Tandy TRS-80 (Z-80)
Later on used Basic on lots of Sinclair Spectrum (Z-80A) models.

Did some work on Z-80 assembly programming.

Then upgraded to a PC (8086 with 640 KB RAM and 40MB HDD with RLL and MFM technologies) with MSDOS 2.2, 3.0, 3.3, 4.0 in the later 80s. I still have lots of floppy disks both 5.25 and 3.5 ones but no disk drives. Kept them for sentimental value.

In this period tried to understand the concept of expanded memory paging!!! (now extinct).

In those days my favorite programs were Norton's Commander and Utilities like Unerase, NDD etc., Lotus 123 and Quattro Pro. I tried to get into Dbase 3 and 4 but till now I could not get a hang of the database management systems.

On windows platforms
Windows 2.0 in 1989
Windows 3.1 in 1993
Windows for Workgroups 3.11 on DOS 6.22 and Novel Netware in 1995
Windows 95, 98, NT4 Workstation, Server in 1995-2000
Windows 2000 Workstation and Server and Advanced Server, XP (Skipped ME and Vista altogether.) and 2003 Server during 2000-2011.

In this period collected few hundreds of CDs/DVDs.

XP was the longest used OS (2003-2011) till date.
Windows 7 2011 (Though started late, one of the best windows so far.)
Windows 8 not tried yet.

In the meantime put my finger in
Unix in 2000
Linux (Red Hat)
Solaris 7.0 and 8.0 in 2000-2001
Pupply Linux
Belenix (Open Source Sun Solaris)
VMWare Workstation etc.

Presently using Apple iOS on an Ipod and Iphones.
Android ICS 4.0.3 on an Asus Transformer TF300T (One of the best Android tablets).
Today, I got the Android 4.1.1 Jelly Bean update from Asus for my tablet.

When I remembered all these OS's I have used till today, it was quite a nostalgic journey of computing in the last 36 years.
