How to Fix 100 Disk Usage in Windows 10
Is your Windows 10 computer crawling at a snail’s pace? You might be facing the dreaded 100% disk usage issue. But don’t worry! With a few simple steps, you can diagnose and fix this problem. We’ll guide you through the process of identifying what’s causing your disk to max out and how to solve it, so your computer can go back to running smoothly.
Step-by-Step Tutorial: How to Fix 100 Disk Usage in Windows 10
You’ll learn how to identify and fix what’s causing your disk to hit 100% usage. Follow these steps to get your computer back on track.
Step 1: Check Task Manager
Open Task Manager by pressing Ctrl + Shift + Esc, or by right-clicking on the taskbar and selecting Task Manager.
Task Manager will show you which processes are using your disk. Look for any programs or services that are using an unusually high amount of disk space. If you find one, it could be the culprit.
Step 2: Disable Windows Search
Press Win + R, type services.msc, and press Enter. Find Windows Search in the list, right-click it, and choose Properties. Change the Startup type to Disabled and click Stop.
Disabling Windows Search can sometimes reduce disk usage because it prevents the indexing service from constantly running and using up your disk resources.
Step 3: Turn Off Superfetch
Open the Run dialog again (Win + R), type services.msc, and press Enter. Locate Superfetch, right-click it, and select Properties. Set the Startup type to Disabled and click Stop.
Superfetch helps preload apps into memory, but it can also cause high disk usage. Turning it off might help your situation.
Step 4: Update Your Drivers
Open Device Manager by pressing Win + X and selecting Device Manager. Look for any devices with a yellow exclamation mark and update their drivers.
Outdated or faulty drivers can lead to all sorts of issues, including high disk usage. Keeping your drivers updated ensures better performance and fewer problems.
Step 5: Perform Disk Check
Open Command Prompt as an administrator by typing cmd in the search box, right-clicking Command Prompt, and selecting Run as Administrator. Type chkdsk.exe /f /r and press Enter. Follow the prompts to schedule a disk check on the next restart.
A disk check will scan your hard drive for errors and fix them, which can sometimes resolve the high disk usage problem.
After you complete these steps, your computer should run more smoothly, and your disk usage should drop from 100%.
