Speed up a slow Windows PC

Find what is slowing the computer and improve it safely.

1. Restart the PC, then open Task Manager with Ctrl + Shift + Esc and check which process is using the most CPU, memory or disk.
2. Open Startup apps in Task Manager and disable only nonessential programs with a high startup impact.
3. Keep at least 15% of the system drive free. Use Settings → System → Storage to review temporary files before deleting them.
4. Install pending Windows and driver updates, run a malware scan, then compare performance after another restart.

Follow the official instructions for your device or service. Back up important data before changing settings or attempting repairs.
