Task Manager


In this article I’ll be explaining about troubleshooting another very common issue in computer, which is showing 100% disk usage all the time in computer. I have note that this status is particularly true on laptops.

If your computer Task Manager shows 100% disk usage in windows 10, something is causing your hard drive to over-work. Your computer is now so slow it’s almost impossible to use.

While using the system the disk usage will go up to 100% for a few seconds or couple of minutes, then it will go settle down to something under 10%. If you consistently see a very high disk utilization, it means there is something else going on that is not right.

You can check your disk usage by opening up the Task Manager in Windows 10. You can either right-click on the Startbutton and select Task Manager or you can press CTRL + SHIFT + ESC.

This issues like as 100% disk usage occur all by itself. It is usually not a hard problem to fix.

If you have installed antivirus programssuch as Norton, Kaspersky, AVG, Avast Behavior Shield. You should temporarily turn them off or disable them to see if they’re causing your disk usage problem.

In this cases, Microsoft has its own default anti-malware, Windows Defender. It’s automatically enabled even if you also have other antivirus applications installed. Even if you disable your other antivirus programs, Windows Defender is always there for you while that definite time range.

So it is helped you to 100% disk usage in windows 10 or 7 or 8.

Method 5 – Disable MSI Mode

This solution is not more clear and probably won’t help majority people, but it’s worth declaring because Microsoft has specifically stated that this is an issue in Windows 10. Basically, it has something to do with AHCI, which is technical jargon you don’t need to know.

how to determine if this is your problem and fix it:

  • Open Device Manager, Expand the IDE ATA/ATAPI Controllers category, and double-click the AHCI controller
  • Go to the Driver tab and click Driver Details. If you can see storahci.sys stored in a path of system32 folder, then you are running the inbox AHCI driver.
  • Close the Driver Details window and go to Details tab. From the drop-down menu, select Device Instance Path. Make note of the path, starting from VEN_
  • Type regedit in the search box of Start panel, then hit Enter on your keyboard to run Registry Editor. Then go to:
  • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ <AHCI Controller>\<Random Number>\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties
  • The <AHCI Controllerhere refers to the name you see from step 2). 
  • The <Random Numberdiffers on different machines. 
  • Double click the MSISupported key and change the value to 0 Restart your computer after the change, then check your computer’s disk usage. if it’s no longer 100%, you’ve fixed the problem.

Method 6 – Reset Virtual Memory

When the RAM is not enough to perform a task, Windows will temporarily store files in virtual memory, then swap them back to RAM when required. 

How to reset Virtual memory?

  • Goto Control Panel and choose the Advanced system setting.
  • Go to the Advanced tab, then click Settings.
  • Go to the Advanced tab again, and choose Change… in the Virtual memory section.

  • Once you’ve entered your virtual memory values, click Set, then click OK to continue.

Method 7- Upgrade Firmware for SSDs

SSDs are fast and unless you have some program that is reading the disk all the time, it really should never be at 100% for more than a few seconds.

Here are a mentioned some of links to the SSD firmware updates.

  • Crucial

Final Words

Switch to ChromeOS

Windows is a very old technology. Sure, Windows 10 is new, but it’s still just the latest iteration of a decades-old operating system.

Windows manages installed software and hardware has always been a problem. If your computer shuts down unexpectedly, or a program installs, uninstalls or updates incorrectly, you can get ‘registry’ corruptions. That’s why Windows PCs always slow down and become unstable over time.

So the simplest way to solve Windows problems is to trench Windows altogether, and switch to a faster, more reliable, more secure, easier to use and cheaper operating system.

Google ChromeOS.

ChromeOS also like Windows, but instead of installing heaps of programs to email, chat, browse the internet, write documents, do school presentations, create spreadsheets, and whatever else you normally do on a computer, you use web apps.

You don’t need to install anything at all and you don’t have virus and malware problems. Your computer doesn’t slow down over time, or become unstable.
