Windows 10 inconsistency

[grandPotatoe]

So when Windows 10 first came out I was one of the few people who told everybody and their dog to install it because it was sooo great. Fast forward a year or so and I feel betrayed.

All PCs below run Windows 10 and every PC runs it differently.

My laptop, which has a 120GB 850 EVO and a Core i7 in it runs smooth as butter.
Laptop 1 with an i5 and a HDD also runs good considering it is a HDD.
Laptop 2, a bit weaker processor + HDD runs terrible. So unresponsive that it is unusable.
Desktop 1 - i5 + HDD runs okay, intermittent unresponsiveness.
Desktop 2 - AMD Phenom X4 9550 + (cheap chinese) SSD, somethimes ok, somethimes 10 min boot times + unresponsive

Desktop 3 - AMD APU + HDD, unresponsive

Now that is what I call inconsistency. Also these systems are not too old, and the hardware in most of them is more than capable. My question is what the hell is going on? Windows 7s performance was reflected on the underlying hardware. Windows 10 just seems to do a dice roll regarding its behavior. Also, most of the time disk usage is in unreal territory when idle. Any suggestions?

Edit: 

I would also like to note that, Prefetch-Superfetch and Indexing is disabled. Windows Defender is disabled. Show me tips about Windows is disabled. Many background services are also disabled.

Windows 10 runs many background processes which can use up disk performance and CPU power. It's not exactly a light operating system. Try turning off many unnecessary startup and background processes in cmd and Task manager.

welp. I have no clue. I run a brand new HDD from Toshiba and an i3 6100 and Windows 10 runs absolutely fine for me.

That is what bothers me. I see no pattern in performance.

That does sound strange. Are they all your PCs? To be honest the only way you can compare the OS on all the different hardware is to wipe them and do a clean install, which obviously is a huge amount of work.

They are all family PCs. And sadly I did a full wipe on all, not just once, and still.

Sorry to hear that.

I hope someone will figure it out, not only for me, but for everyone who has a similar problem

Never disable prefetch/superfetch if you use a HDD. 
 

It may be a good idea to run Procmon and check what those PCs are doing. If there's nothing unusual going on in Procmon, then check for driver problems (updating to newer ones or rolling back to drivers provided by the manufacturer). If those can't solve, check for fragmentation and HDD health, and then a memory test.

I will check for those (sadly only in a week), thank you.
