Disk usage stuck at 100% and everything is slow
Open Task Manager and look at what's using the disk. Windows Update, antivirus, or cloud backup. Once you find it, pause it or wait for it to finish.
When your disk is stuck at 100%, it means something is reading or writing to your hard drive constantly. This is probably Windows updating itself, an antivirus scan running, a cloud backup uploading files, or even malware. We'll find out what's using the disk and either stop it or wait for it to finish.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
Skip — I just want a technicianCommon mistakes to avoid
- Restarting immediately instead of checking what's using the disk first. You'll just see it happen again after restart
- Stopping an important Windows process thinking it's the problem. Stick to cloud backups, antivirus, and programs you recognize
- Not realizing that cloud backups running during business hours are the most common cause of this problem
