Malware and viruses can significantly impact your system’s performance, including disk usage. It’s crucial to regularly scan your computer using reliable antivirus software to detect and remove any malicious threats. Keep your antivirus software up to date to ensure comprehensive protection.

5. Upgrading Your Hardware

If none of the above methods resolve the 100% disk usage issue, it may be time to consider upgrading your hardware components. 

An SSD (Solid State Drive) can provide faster read and write speeds, significantly reducing disk usage and improving overall system performance.


In conclusion, dealing with 100% disk usage can be frustrating, but with the right techniques, you can overcome this problem and enjoy a smoother computing experience. 

Remember to update your device drivers, optimize system settings, perform regular disk cleanup, scan for malware, and consider hardware upgrades when necessary.
