Why does the computer lag and lag?

Question

Windows

A week ago I still had an old laptop, now a new one.
Specifications of the old one:
dell inspiron 5558
intel core i3-5005U
ddr3l - 16gb
nVidia GeForce 920M, 2gb
ssd sata 256gb
hdd sata 500gb
windows 10 pro which version is described below
It worked and worked fine. Naturally, he did not pull out 4k. He was just slowly, but doing his job.
Specifications of the new:
dell g3
intel core i7-8750H
ddr4 - 16gb nvidia geforce
gtx 1060 max-q 4gb
ssd m2
500gb hdd sata 1000gb
windows 10 pro which version is described below i
'm sure it should be enough to watch videos on youtube, sublime and filezilla
The difference between the two laptops is huge.
But they have one thing in common. They are both dumb.
The first is logical, because it simply does not meet modern requirements.
The second - ....
And here is the question: - maybe I'm doing something wrong?
List of programs that are installed on both one and the second:
aimp
classicShell
faststoneCapture
FileZilla
notepad2
paintNet
preme for windows
rocketDock
sublimeText 3
tClock
vivaldi
win RAR
awesome photo finder
Firefox
KeePass
npp
Punto Switcher
putty
chrome
whatsap
skype
viber
telegram
office
All programs are installed from off sources.
Windows was activated via kms auto, which was downloaded from here https://myfreeproject.com/soft/81-kmsauto-net-2016.html
Office was once downloaded from torrents. Office also activate kms auto.
Windows was downloaded from here https://uup.rg-adguard.net/?lang=ru-ru

By occupation I am webdev.
The following programs are permanently open:

Programs from the list that are designed to work in the background:
aimp
classicShell

It costs extra. monik. On one is the entire list of permanently open programs including vivaldi, on the second, an additional monica - vivaldi (youtube is open)
I want to understand the reason, get to the bottom of the truth. I don't want to live impulsively and impulsively jump to conclusions.
When something on the site does not work, I find exactly that line of code, exactly that section of code in this line where there is an error.
And when I look at this line, I clearly see this error.
Then I edit this section, try again and see the result - the code works, the error has disappeared, the problem is solved.
I want to get the same result here:
If the computer lags because of some file, I delete it - the computer stops lagging.
If the computer lags because of some program, I delete it - the computer stops lagging.
If the computer lags because of the curve of Windows or it is the insider assembly to blame, I reinstall it to the assembly standards - the computer stops lagging.
Please don't throw words to the wind. You can say that the problem is in classicShell, for example, I'll go ahead and remove it. And I'll unsubscribe that after removing the lags still continue. But by this point, you don't give a damn, and you won't contribute to the further search for the cause. Then a person will come who will call me a moron and leave (according to personal observations, usually when a person does not have an answer to a question asked on a toaster, he does so). After you come another person who will say that the problem is in sublime text, I will go and delete it. And I'll unsubscribe that after removing the lags still continue. But by this point, he doesn't care anymore, and he won't contribute to the further search for the cause. Then a man will come who will call me a moron and leave. After him, another person will come who will say that the problem is in aimp, I will go and delete it. And I'll unsubscribe that after removing the lags still continue. But by this point, he doesn't care anymore, and he won't contribute to the further search for the cause. Then a man will come who will call me a moron and leave. After him, another person will come who will say that the problem is in windows, I will go and reinstall it. And I'll unsubscribe that after reinstalling the lags still continue. But by this point, he doesn't care anymore, and he won't contribute to the further search for the cause. Then a man will come who will call me a moron and leave. I'll go and reinstall it. And I'll unsubscribe that after reinstalling the lags still continue. But by this point, he doesn't care anymore, and he won't contribute to the further search for the cause. Then a man will come who will call me a moron and leave. I'll go and reinstall it. And I'll unsubscribe that after reinstalling the lags still continue. But by this point, he doesn't care anymore, and he won't contribute to the further search for the cause. Then a man will come who will call me a moron and leave.
As you can see, this will lead me to a dead end, as a result, I will reinstall programs and operating systems until my death on your impulse, but the result does not wake up and no one will be able to find “that line of code” in which the error.
Therefore, I will not remove classicShell because I understand that you are pointing your finger at the sky.
Therefore, I ask you not to point your finger at the sky, but to solve the problem.
It is necessary to understand exactly what is the reason and get the result.
It's not right now. The lags do not appear right now, they appear sometimes.
As it lags: desktop background images do not switch smoothly but abruptly (I have 50823 desktop background images, they switch every 10 seconds (I’ll make a reservation right away that I tried to turn them off, no, the problem is not in them)), when dragging windows, they are dragged very slowly when this twitching. When you open a program or explorer, he or she takes a very long time to draw, the interface is drawn. When you press alt + tab or other key combinations, the action that is bound to these keys is performed after half a second, a second. With very large lags at the time of typing, the letters are drawn with a delay.

Answer 1

The problem is classicShell. Delete it.

Answer 2

It is possible to advise to be at war with WMI (Windows Management Instrumentation).
But as this tooling gets deeper and deeper into the carcass of Windows, and there are more and more dependencies and restrictions, then you will simply lose and resign yourself.
PS Install Windows 7, it has less WMI. And if you remember about Windows XP ...
Or the second option, Sysinternals Process Monitor will help you. It's a pity he won't show all the WMI trash and waste.

Answer 3

The difference between the two laptops is huge.

Approximately the same laptops in terms of performance. The new one is a little better.
But there is also Windows 10 - a bigger load.
Not sure how much RAM.
The indicated tasks should be pulled without any special brakes, but you should not expect any performance from it either, this is a laptop.
Before solving the problem, you need to at least conduct a diagnosis. Do you really think that it is possible to treat by photography?
Look at the disk queue, memory usage, processor usage.
According to the symptoms, it seems that there is not enough RAM, although it can be anything. From faulty hardware to a miner in the system.
