Quick Note Before You Begin

• Make sure your Windows 11 is up to date. Updates often include fixes for known issues.
• Check that your USB devices are properly connected and powered on.
• Have administrator access on your computer, as some steps require changing system settings.
• Create a system restore point before making major changes, so you can revert if needed.

Step 1: Restart Your Computer

Sometimes, a simple restart can resolve temporary glitches affecting swusb.exe. Restarting clears out system memory and refreshes background processes.

1. Click the Start menu and select the Power button.
2. Choose Restart and wait for your computer to reboot.
3. After restarting, check if the swusb.exe error still appears.

If the problem continues, proceed to the next step.

Step 2: Run a Virus Scan

Malware infections can cause swusb.exe to malfunction. Running a full virus scan helps detect and remove any harmful software.

1. Open Windows Security by typing “Windows Security” in the search bar.
2. Click on “Virus & threat protection.”
3. Choose “Scan options” and select “Full scan.”
4. Click “Scan now” and wait for the process to complete.

If threats are found, follow the prompts to quarantine or remove them. Restart your PC and check if the error persists.

Step 3: Update USB Drivers

Outdated or corrupted USB drivers can cause swusb.exe errors. Updating drivers ensures compatibility and smooth communication between your system and USB devices.

1. Press Win + X and select “Device Manager.”
2. Expand the “Universal Serial Bus controllers” section.
3. Right-click each USB device and choose “Update driver.”
4. Select “Search automatically for updated driver software.”
5. Follow the instructions and repeat for all USB entries.

After updating, restart your computer and test USB functionality.

Step 4: Check for Windows Updates

Microsoft regularly releases updates that fix bugs and improve system stability. Installing the latest updates can resolve swusb.exe errors caused by system issues.

1. Open Settings by pressing Win + I.
2. Go to “Windows Update.”
3. Click “Check for updates.”
4. If updates are found, download and install them.
5. Restart your PC when prompted.

Step 5: Run System File Checker (SFC) Scan

Corrupted system files can interfere with processes like swusb.exe. The System File Checker tool scans and repairs these files automatically.

1. Type cmd in the search bar.
2. Right-click “Command Prompt” and select “Run as administrator.”
3. In the command window, type sfc /scannow and press Enter.
4. Wait for the scan to finish. It may take some time.
5. If issues are found, they will be fixed automatically.

Restart your computer and check if the error is resolved.

Step 6: Disable Fast Startup

Fast Startup is a Windows feature that speeds up boot times but can sometimes cause conflicts with drivers and processes like swusb.exe.

1. Open Control Panel and go to “Power Options.”
2. Click “Choose what the power buttons do.”
3. Click “Change settings that are currently unavailable.”
4. Uncheck “Turn on fast startup (recommended).”
5. Save changes and restart your PC.

Step 7: Perform a Clean Boot

A clean boot starts Windows with a minimal set of drivers and startup programs. This helps identify if third-party software is causing the error.

1. Press Win + R, type msconfig, and press Enter.
2. Go to the “Services” tab.
3. Check “Hide all Microsoft services.”
4. Click “Disable all.”
5. Go to the “Startup” tab and click “Open Task Manager.”
6. Disable all startup items.
7. Close Task Manager and click OK in the System Configuration window.
8. Restart your computer.

If the error does not appear after a clean boot, enable services and startup items one at a time to find the culprit.

Alternative Method: Reinstall USB Controllers

If updating drivers did not help, reinstalling the USB controllers can fix corrupted driver installations.

1. Open Device Manager (Win + X > “Device Manager”).
2. Expand “Universal Serial Bus controllers.”
3. Right-click each USB controller and choose “Uninstall device.”
4. After uninstalling all, restart your PC.
5. Windows will automatically reinstall the USB controllers.
