Fixing 100% Disk Usage in Windows 11

Tired of your Windows 11 running slow because of high disk usage? Don’t worry, it’s a common problem and can be fixed! By following a few steps, you can easily reduce disk usage and make your computer run faster. Let’s dive into some simple yet effective ways to get that disk usage down.

Step-by-Step Tutorial to Fix 100% Disk Usage in Windows 11

These steps will help you identify and fix the issues causing high disk usage on your Windows 11 PC.

Step 1: Open Task Manager

Press Ctrl + Shift + Esc to open Task Manager.

Opening Task Manager will allow you to see which processes are taking up the most disk space. Look for any that are at or near 100%.

Step 2: Disable SysMain Service

Press Win + R, type "services.msc", and press Enter. Find SysMain, right-click it, and select Stop.

SysMain (formerly known as Superfetch) can sometimes cause high disk usage. Disabling it can help reduce the load on your disk.

Step 3: Check for Malware

Run a full system scan using Windows Defender or your preferred antivirus software.

Malware can cause high disk usage. A full system scan will ensure that your PC is not infected.

Step 4: Update Windows

Go to Settings > Update & Security > Windows Update, and click Check for updates.

Updating Windows can fix bugs and improve system performance, including reducing disk usage.

Step 5: Change Virtual Memory Settings

Open System Properties by pressing Win + Pause/Break. Click Advanced system settings, then Settings under Performance. Go to the Advanced tab, click Change under Virtual Memory, uncheck Automatically manage paging file size for all drives, and set Custom size.

Adjusting virtual memory can help in managing disk usage better. Set the initial size to 1.5 times your RAM and the maximum size to 3 times your RAM.

Step 6: Disable Windows Search

Press Win + R, type "services.msc", and press Enter. Find Windows Search, right-click it, and select Stop.

Disabling Windows Search can prevent it from indexing and using up disk resources.

After completing these steps, you should notice a significant drop in disk usage, leading to improved system performance.
