9 Tips To Fix 100% Disk Usage Issue On Your Windows PC

Did it ever happen to you that your Windows PC is not responding except for the mouse and when you open task manager by pressing “ctrl+alt+del“, you discover your system drive running at 100%? This is mostly found in Windows 10. Yes, you heard that right. Theoretically, the most advanced and optimized version of Windows has this issue. The problem, in reality, is not that you are multitasking beyond the limit or performing CPU and GPU intensive tasks but an optimization issue or bug that has crept in lately.

Honestly speaking, I never noticed the similar issue on my Windows 10 PC but since many of you Windows 10 users have been reporting this, here are a few tips that might help you this issue on your Windows 10 PC. Many even reported that it not only affected Hard Disk Drives (HDDs) but Solid State Drives (SSDs) as well.

Run Full Scan To Search For Malware

Many have reported that applications like Google Chrome, Skype, SuperFetch, Media Players etc. gave rise to disk usage issues. Some even reported that while they only listen to music and having no other application running in the background, similar issue crept in. I don’t think the media player would be responsible for keeping your hard drive busy up to its full capacity. The 100% disk usage problem might have occurred if your system is infected with some malware. In these cases, the first thing that one should do is to run a full scan of his/her PC on Windows Defender or any other similar application. If threats are found, use the software’s recommendations to discard them, and reboot, before checking your drive performance further.

Issue With Google Chrome

If you are noticing that while you are using Google Chrome with no other application running in the background, your system showcases 100% disk usage issue, follow these steps:

  • Open “Google Chrome.”
  • Click on the three dots icon present on the top right corner of the screen.
  • Click on “Settings.”
  • Click on “Show Advanced Settings.”

  • Once you are done with the 3rd step, close all the applications and reboot your device. While restarting, it will scan your local disk drives and hence, can take longer than usual while booting in.
