I was (for many years) running XP (I didn't run Vista at all). However, I ran XP in "Classic" mode, so it looked like Windows NT.
I wouldn't mind switching Windows 7 to look like Windows NT, too - the new UI hides some of the things I want to see. Took me a while to find "Add/Remove Programs", for example. Not impressed by the new Control Panel, either.
One of the first things I do on a new installation is to switch off the hiding of file extensions (HATE that!). I turn on viewing hidden files, and operating system files. I'm a low-level systems developer, so I like to know where things like BOOTMGR and NTLDR are located. Windows 7 annoyed me by moving the BCD off to a hidden partition (don't worry, I can get access
So if you think the OP is living in the past by wanting to see Windows 7 looking like Windows XP, do I qualify as worse for wanting to see Windows 7 looking like Windows XP looking like Windows NT?
