What the checks cover
The four options address different parts of the running Windows installation. Select at least one option to enable Check.
| Option | What it checks | Repair behavior |
|---|---|---|
| Check component store | The health of the Windows component store used for servicing | Uses Windows servicing functions to restore the component store. |
| Check system files | Protected Windows system files | Uses System File Checker to verify files during the check and to repair them during the repair pass. |
| Check disk | File-system consistency on the configured system drive | Requests a file-system repair through the Windows disk-checking functions. |
| Check Windows recovery environment | Availability and version suitability of the recovery image | Attempts to restore a suitable Windows recovery environment. |
Choose the scope
For a general check, leave all four options selected. To investigate one reported problem, select the relevant area. The result describes only the selected checks; it is not a complete hardware or malware diagnosis.
The disk check concerns file-system structures. It does not estimate the lifespan of a drive and does not replace a hardware health test. The window of Check&Repair has no drive picker.
The tool runs the selected checks in this order: component store, system files, disk, then recovery environment. Some steps can take several minutes, and their progress can advance unevenly.
