How to Check Your PC's Health on Windows
A short health check every few months can catch problems before they become failures. Here is a simple routine using tools already on your PC.
1. Windows Security & device performance
Open Windows Security → Device performance & health. It reports on storage, battery life, apps and software, and Windows Time service.
2. Storage drive status
Go to Settings → System → Storage → Advanced storage settings → Disks & volumes. Select a drive and open Properties to view its health and remaining life on supported drives. A warning here is a signal to back up immediately.
3. Battery report (laptops)
Open Command Prompt and run powercfg /batteryreport. Windows saves an HTML report showing design capacity versus full-charge capacity. A big gap means the battery has worn down.
4. Memory check
If you see random crashes, search for Windows Memory Diagnostic, choose to restart and check for problems, and review the result after reboot.
5. System file check
Run Command Prompt as administrator and enter sfc /scannow. It scans protected system files and repairs damaged ones.
6. Temperatures and dust
If fans are loud or the case feels very hot, dust is a likely cause. See how to clean your PC safely.
