Restarting your PC is still necessary, but how often depends on your system. For Windows, a weekly reboot is recommended to clear memory and fix minor issues. Laptops should be shut down when not in use to prevent overheating, especially if stored in a bag.

A full restart resets the memory, clearing background processes and potential malware. However, Windows' Fast Startup feature can prevent a true reboot, so use the Restart option or hold Shift while shutting down. Always reboot after major updates to finalize installations.

The frequency ultimately depends on your usage and system performance.
