System Health

Windows System Health

To check the system health on your computer simply follow the steps below. Run Windows Terminal (Windows 11), CMD (Command Prompt) or Windows PowerShell as administrator.

Deployment Image Servicing and Management (DISM) tool

1. Type in the following code and then press enter. DISM will run and verify any data corruption that may require fixing.

DISM /Online /Cleanup-Image /CheckHealth

2. Next we will run DISM with ScanHealth. This advanced scan may take several minutes to check and determine whether the Windows 10 image needs repairing.

DISM /Online /Cleanup-Image /ScanHealth

3. The next step will run DISM with RestoreHealth. DISM will connect to Windows Update online to download and replace damaged files, if it found any.

DISM /Online /Cleanup-Image /RestoreHealth

Free Up Space

DISM can also help you free up disk space on the drive. Before you tell it to do so you can analyse exactly how much space the component store is taking on your computer. The component store is where all your restore points are saved on your drive, which lets you roll back Windows to an earlier state where it worked.

DISM /Online /Cleanup-Image /AnalyzeComponentStore

To clean up and remove all historical updates except the most recent ones, so that you still have one version to roll back to, run the following command:

DISM /Online /Cleanup-Image /StartComponentCleanup

When it’s done you can run the analyse command above again to see how much space was freed up.

System File Checker (sfc) tool

4. When you have run the above tool (DISM) it’s time to run the SFC. This tool will repair corrupt files if it find any. After it has finished restart your computer and your computer should run much smoother.

sfc /scannow
