definitely love win 7.. win me was my fav before that.. I didn't like XP and I think most people didnt but now say they like it just because vista was so much worse it made xp look decent.
What? You liked Windows ME? No way. Back when I had that junk OS, literally not a day went by without me getting a BSoD for some stupid reason, like ME not appreciating sound or video drivers, etc. I heard that even Bill Gates admitted that ME was Microsoft's worst OS ever. It didn't even need my help to crash itself.
As for Windows 7, though, it's fantastic. I never want to see XP again. I love the new taskbar system, with the window previews and auto-grouped programs - it's clean and seriously easy to use, plus I can look at another window without actually opening it.
I also really like how the start menu keeps track of recent files within the individual programs that open those files (i.e. MS Word keeps a list of recent *.docx files opened). It's a huge improvement over the original Recent Documents folder, which I never used.
I love how I can hide system tray icons. That particular feature has been needed for a decade now.
I love how I can actually turn off UAC. Unlike some people, I know what I'm doing and don't need to confirm it 3 different times.
I love how Windows 7 handles network services and wireless networks. On XP, you had to create a network before adding a wireless connection, and if you named that connection incorrectly, your wireless peripherals (printer, NAS drive, whatever) wouldn't work. Windows 7 sets up the network automatically as soon as you get internet access through your network's router, which probably saved me a huge headache.
The OS is also very responsive, and doesn't seem to get bogged down by its own system processes after a few days of not being restarted. I admit though that I still don't like how in both Vista and 7 that Ctrl+Alt+Delete doesn't just immediately open the Task Manager. While I've not yet seen it in Windows 7, Vista had an issue with occasionally failing to open that dialog box, which of course made it impossible to get the Task Manager open.
So yeah, I like 7.
