IMHO, my top three favorite versions of Windows are Vista, 7 and XP. Vienna is most memorable to me because it was my first version of the operating system that came with a Packard Bell EasyNote LS11HR laptop (at that time, it was a very good laptop with 6 gigabytes of RAM, an i5 processor and some kind of video card by Radeon (or what), definitely not I remember, but the sites said that this is a gaming laptop). There were very good and pleasant times, as I remember all this with pleasure, nothing lagged, everything worked perfectly, and this interface... It hooked me with something. But this "something" keeps me still. But! Now you ask why I put Vista in the list of my favorite systems? Because I have been using it since 2017, and this is a cool thing that I will not reinstall for at least a few years, since I really love it, and with the release of the extended kernel from @win32, I definitely will not move until then, until the creator of this thing can, for some reason, add new functions, and the programs will no longer connect to servers or something else. Also, I really love her interface, it is even better than in 7, which I also love, and I will never forget, I just want stable work from my computer, and with Vista it became possible. Yes, I still have this laptop, it is running Windows 7, my dad uses it, since the discrete video card for some unknown reason stopped working, unfortunately. But now I use a computer with modest specifications, but they satisfy me: GTX660 Palit, Xeon E5440, 8GB DDR3. It works perfectly on this hardware. Also, I fell in love with XP, I used it until 2014-2016, then I moved, as mentioned, to Vista. I used it because it was very stable, and then it was just interesting for me to explore it, but yes, those were interesting times. Moving on to what I hate, it's 10. I used it for a few months, but then switched back to 7, but after a while already on Vista. I do not want to use 10, since it simply wastes my perfomance of pc to nowhere, for some unknown reason: 2-3 gigabytes of RAM, when on Vista there is only 1 gigabyte, I also don’t particularly like surveillance, which is very much on 10, ex. And I also just don't like the Metro interface, I don't like minimalism, it's just not mine
