Win10 slow performance, 100% disk usage, system Freezing and crashing. .. Fixed | ReAndroid Community

Presenting excellent fix for your Windows 10 computers facing issue with 100% Disk Usage.
Win 10 Issue 100% Disk Usage

Sometimes people can't understand why brand new Windows 10 computers are very slow, lags & freezes a lot and some time even crashes. In fact, I found some out of box computer behaving in the same way.

Some people start to think of such PCs as a piece of crap/lemon/junk.


I just want to tell you that it is a simple software issue.


Just open Taskmanager using Cortana and click on show more options, and you will see which services and apps are causing this trouble.

This issue has caused PC manufacturers millions & billions of dollars in product returns and servicing them. Because most of us don't even try to fix it. Whoever attempted to fix this problem, it cost them time and effort.

Let's now talk about fixing it!


Step 1

See if you have the Google Chrome browser on the computer because Google chrome is one of the slow performance reasons on win10.
Prediction service in chrome browser seems to be conflicting with Windows 10 services and causing 100% disk usage.
Go to the settings of Chrome browser then go to advance there you will find predictive options, just unchecked it.

Step 2:

Check if you have Skype installed on the computer :
Make sure you have exited Skype, and it is not running in the taskbar (if it is running in the toolbar, then quit it).
Open Windows Explorer and open the following folder:
"C:\Program Files (x86)\Skype\Phone\"
Now right-click the "Skype.exe" file and then click "Properties" and open the "Security" tab.
Click the "Edit" button and then highlight "ALL APPLICATION PACKAGES" and place a tick in the "Write" box.
Click "Apply" and then "OK" and then "OK" again.

Step 3:
Go running box by pressing Windows key + 'r' on the keyboard, now type in MSConfig click OK.
It will pop up a system configuration box.
In this box, go to services, there would be an enormous list of services.
You have to find out for the Superfetch and the windows search service, find them, and uncheck both of them.
To make it easier to find, you can simply type Superfetch really fast; it will take you there. Do the same for Windows search, but when you press the space-bar, it will disable Windows module service, which then you have to scroll up and enable again.
Click Apply, and then OK following these, it will ask you to Restart, perform the Restart.

Step 4:

In this step, you need to right-click on the windows icon, then select device manager in there look for ATPI adapter with green chip icon, click on the arrow left to it, underneath it you will see one option, double-click on it. It will pop up device properties box, go to details, in there from drop-down, select Hardware ID, now in the list make a note of first Hardware ID.
Now again, go to the RUN box, remove MSConfig from there, and put in Regedit.

In Regedit(Registry Editor), select "System>current control set>enum>PCI>," here, now look for the entry which looks like the Hardware ID we noted earlier (From "Device manager).

Now, <Hardware>> Expand Device parameters>" under which on the right side you will have MSI Support double click on it. You will see the value assigned to it would be 1 make it 0.

Close the Regedit.

Hopefully, it will resolve the issue if not, then create a new user's account and go to the settings>Account add new local account and try it.

Step 5 (Not for the customer who is using Windows 10 1803 Built, if not sure about it avoid step 5) Disabling Windows Defender.
Still not working then need to run PowerShell commands to reconfigure some Apps:
Windows defender: Found it to be conflicting with 3rd party antivirus apps so to disable it run PowerShell commands >

Set-MpPreference -DisableRealtimeMonitoring $true

Check if it makes a difference.
Try this Windows Defender Uninstaller (Not for the customer who are using 1803)Following the above command try this following commands on command prompt:
sc stop windefend
sc delete windefend
Then fix below registry:
Next, you need to grant full permissions to and delete the following registry key so the Defender Control Panel entry can be deleted:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
\ControlPanel\NameSpace\{D8559EB9-20C0-410E-BEDA-7ED416AECC2A}
3. Also, grant full permission and delete the Defender program registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender
4. Now delete the following folders:
C:\Program Files\Windows Defender
C:\ProgramData\Microsoft\Windows Defender
C:\Program Files (x86)\Windows Defender (for 64-bit users only)
After that is done, the Defender should be removed. Windows may complain that the Defender is turned off, but this will disappear after a reboot, or you can go into Action Center and tell it not to monitor your anti-spyware software.
Step 6:
Still not fix then run below PowerShell commands:

Use the Powershell command

  1. Press the CTRL + SHIFT + ESC hotkey combination to open the task manager.
  2. Click File, then, and choose Run New Task from the drop-down menu.
  3. Type PowerShell in the Open line of the create New Task pop-up window and click OK.
  4. Now right-click PowerShell from the taskbar and select Run as administrator from the pop-up menu.
  5. Now copy/paste the following command in the command prompt of the Powershell Window that has a blue background:

    Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

  6. Press the ENTER key. Wait for the command to finish then reboot your system.
If still running slow and task manager still shows 100℅ disk usage then try another PowerShell command:
Dism /Online /Cleanup-Image /RestoreHealth
Step 7
Go to the c:\Users\username\Appdata\Roaming folder and delete everything in there will fix the problem.
A small tip here: If you get any errors that Microsoft Windows can't delete some file, don't get confused; just simply skip that File.
Step 8
Check for multiple Antivirus installed on the system; if found, then remove one of them.
You can do it by going to Programs & Features.
Step 9
Create a custom data collector set to monitor and control the performance of your PC.  Check my other article for it. Click here.
Step 10
Reinstall Audio drive, especially if you have a Realtek Audio controller in the device manager.
You need to install it in a different way to check this link for it; this link is for the separate issue but uses the same techniques to install the driver, which required to resolve this issue. Click here to check it out.

Step 11


Download Windows 10 ISO from Microsoft reinstall the fresh OS.
I added too much info collaborated with different sources.
Believe me, the first 4 steps are generally required.

Note:  Above performing above steps and given content needs computer expertise on computer, and knowledge to back up the computer files and information. Ensure you can backup all your essential files and data; otherwise, you will lose them. 
If, after doing all the above steps, your computer is not working, kindly contact the device manufacturer and explain the situation; they will try following the above steps, but just confirm with them that you have tried this. You also tried doing the OS installation from the Microsoft Media Creation tool, and there is no Dell software or Third Party software installed on the system anymore. 
What Manufacturer should do in this case: As reinstalled Windows and still facing the issue, that indicates there is something inside the computer which is not working in sync with the HW and OS installed. They will certainly take the matter to there higher technical expertise and try replacing some Hardware components of the computer with the different Manufacturers, and it will eventually resolve the issue. 

Tips: Do remember that, after performing the above-suggested steps, if we are still facing this problem, then it means the HardDrive is weak for Handling Windows10. Report this problem to the Hardware Vendor and let them decide if they agree to proceed to replace the Hard Drive with the one which has better Cache Memory embedded into it.
