I am having a problem with Windows 10 Pro.
Disk usage is 100% or Memory is 100%
I have tried several solutions searched on the Internet, but it still remains the same.

It usually occurs with New Installation

Open Task Manager/Resource Monitor and check which processes use your resources the most.
I've seen antivirus scans/Windows Update loading the system after a fresh installation.

Hi
Besides the above, below reasons also cause the disk 100% usage:
  • Some bad sectors in Hard drive
  • Hard drive free space is very less
  • Page file is occupying full capacity of drive
  • Windows indexing is running
However, Taskmanager will show you what process occupies the resources, as Hello There mentioned.

On a new installation: it will be the indexing (search) service which runs at a low priority so it has almost zero impact on running the operating system.

Do you have an HDD or SSD? If SSD, make sure that the firmware is up to date.
Does it happen with all new fresh installs?
What happens if you reboot a computer/laptop?

Most probably it's a 5400 rpm HDD.
It wouldn't play nice with Windows 10. if that's the case, better go for SSD, if you still have replacement possibility.

So the system is showing that your disk is running at max speed, this is typical of a WIN10 system at startup, and can last upto 15 minutes.

It looks like you have a HDD, these devices have two measures of performance, MegaBytes per second (MB/s) and I/O operations per second (IOPS). for a 5400 rpm Disk that you will typically find in a laptop, you are looking at max 100MB/s and max 100 IOPS - BUT they are mutually exclusive.

Whatever WIN10 is doing you have run out of IOPS thats what the 100% means. If this lasts longer than 30 minutes, you need to take it to a repair shop for diagnoses, otherwise the best cure is to replace the HDD with an SSD (500MB/sec and 10K IOPS), something like a Samsung Evo

At which point? Right after you install the system? Them it might be Windows updates. After you install software like antivirus, MS Office, etc?
