In 2008 to 2013, we had a LCD and a CRT monitor with a personal computer that had Windows XP, then in a new year when I was 7, I got a HP Pavilion DV6000 Entertainment PC and it doesnât connect to the wireless network and I use a network cable.
Windows 3.1
Windows xp, its the best!
Windows 7, my favorite OS ever made.
xp vista and 7
technically mine was Windows 2000 =P
XP.
Very late to the party, but it definitely has to be Windows XP and Windows 7.
Windows XP was the very first OS I was introduced to, because it was the first time I used a computer, and I filled that thing up with Dora the Explorer trial games from shockwave and wildtangent pretty fast.
I also used Windows 7 a lot after that, and it pretty much became iconic for me.
I even remember installing Windows 10 on my very first Windows 7 Laptop I owned personally back when the Free Windows 10 Upgrade started, and the laptop had a lot of problems after that.
lol itâs funny
mine was xp and still have it, just that i formatted it
(canât edit this one anymore, so i remake itâŚ)
Back then i was born thereâs a PC running Windows XP (SP2, at the time)
Also i use Internet Explorer back then, until switched to Google Chrome, Firefox, Edge Chromium, Opera GX and again to Mypal/Pale Moon-based.

Windows Embedded POSReady 7 (installed in June 11, 2020), broke for some reason, and transformed to Windows XP (partially)
Windows Vista (not installed Extended Kernel, installed March 22, 2020), unused since then and might want to reinstall

2020 (second gaming PC):
Windows 8.1 (installed on July 21, 2020), needs to reinstall because Aero Glass wonât run on startup and instead its Queued (checked in Task Scheduler) for hours and its still wonât run.
Windows Vista (installed July 22, 2020)
