Windows 10 working with 16GB RAM and a Core i7 2.4 runs beautifully , If you find it slow it can be for two reasons

a) You have a malawere that slows down the process. Or on the contrary you have an antivirus that inspects everything at all times and slows the device.

b) You run several very heavy processes at once, for example video editing and work with large Excel tables,

c) The machine works perfectly but you are a prisillas.

You should note if you do not have Windows updates downloading or installing, sometimes this consumes system resources which results in a slower operating system.

You have to analyse, which services are active and running, and analyse within these the consumption of microprocessor, and Ram. That will tell you clearly what is going on, go to the task manager. Ctrl+Delete. You can disable what you are not using and let the operating system load at boot time. Now on the other hand. Put in the balance on side A what you need to be loaded and on the other side what hardware you have available for use, there should be a balance, also always more hardware power than hardware consumption.

How can I make Windows run faster?

Note: If your computer is downloading and updating Windows, for example from build 1703 to 1803 or from 1803 to 1903 it will become very slow, leave it on overnight, let it do its job, if it asks for a reboot do it, in the end you will have a much faster and more stable computer.

I don't know what generation your processor is what is certain is that with exposure to smart phones and other devices that run on FLASH drives instead of hard drives like our computers do make our computers seem slow, I can assert to you that windows did not suddenly become slower, it is just pretending to be your phone while still using computer hardware, buy an SSD to replace your hard drive and I guarantee you will be much happier with your equipment.

The only thing you need to do is to disable the pagefile, I think Windows defender protection is very good, it beats most antivirus products.
