shadow copy service

The shadow copy service, also known as Volume Shadow Copy Service (VSS), is a core Windows component that enables System Restore to create and manage restore points. When this service is not running, disabled, or corrupted, restore points may fail to be created or go missing entirely. Common causes include disabled system protection, low disk space, or corrupted system files. Troubleshooting steps involve verifying the service status, re-enabling system protection, and ensuring sufficient disk space. Restarting the shadow copy service or using system file checker tools can often resolve issues. Proper operation of the shadow copy service is essential for reliable System Restore functionality in Windows 10 and Windows 11.
