For me windows 10 is best then windows 7
WIndows XP and all older OS have never been good. A lot of issue, bugs, poor security/firewal, not great for multi-taskings, very limited options. etc. WIndows 7 was massive improvement over it in every possible way. All all older OS were pain to use and not user friendly.
WinXP was the most intuitive OS Microsoft made. It had bugs, but so has every version including 10. At least with XP I don't ever remember an update that screwed up your system the way it has with 10, and more than once.
Win7 was decent. Win10 is spyware. I use it for gaming and that's it. Otherwise I use Win7 on an older machine and for the machine I game on, when I'm not gaming, it runs Ubuntu (2 OSs on one PC), and since I like the MATE DE, which is an offshoot of Gnome 2, it is far and away the best desktop experience for me personally and for all the software I used from Windows, it either runs it or there is replacement software I use. I don't use Microsoft Office for instance for about 5 years now. My wife's machine runs it though on Win8.1 (which at least isn't spyware), and I'll use it because of Visio. I could run replacement software for it under Ubuntu but I've used Visio now for about 15 years so I'd rather stick with it.
The only Win versions that had a good File/Windows Explorer is Win98, ME and XP and XP was the best. Later than XP have behaviors that are stupid. I can at least load Windows classic shell over Win7 and fix the stupid behaviors of File Explorer, but the creator of that software gave up on Win10 because it changes too much.
Honestly Win10 is about the worst thing you can put onto a business system because you need consistency. You can't have employees get frustrated because the way the machine is configured gets changed by the OS.
Finding settings in Win10 is total GARBAGE. A tiled interface isn't good for a PC. It really means you get an ugly DE since you have HUGE buttons staring at you. Win10 pushes its store at you and requires much more customization for me to tolerate it for every day use. Updates can screw up your settings. Right clicks are much less powerful (options) than with XP.
With XP, you got almost everything from clicking the start button. What a NOVEL idea. Find almost everything from a single click! Then the quick launch bar which was easier to customize
I used to say I like Windows because it stays out of your way, but Win10 has been the most invasive piece of CRAP, and if I didn't need it for DX12/DX12 Ultra, I wouldn't touch it. But hey, it got me off my butt to try Linux and I discovered that I like Ubuntu MATE way more than Windows, any version, well, other than the default file explorer, but the neat thing about Linux is you can import many tools, so I actually have 2 file explorers on the system, and one comes with a bulk rename utility. Pretty convenient. Now it's Linux, or for me it's really Ubuntu that stays out of my way and lets me get to the things I want to do without bothering me. It's also faster than Win10 and is better for multi-tasking than any Win version. It also moves files faster. I'm one click away from everything I do on a normal basis, and it doesn't take up screen space since everything is on a taskbar. I could also go through a menu system like what XP gives. I can even launch settings from a taskbar. It also gives a 2nd bar (one top, one bottom) which gets out of your way and it shows open apps, so if you're running a lot of apps at once, you don't get an overly crowded taskbar if you're the kind of person who pins a lot of stuff to the taskbar.
I think that sums up my issues with Win10, and the best part about it for me was leading me to Ubuntu MATE.
