This is a difficult question to answer, as it depends on the version of Windows you are running, what type of hardware your PC has, and other variables. Generally speaking, it’s best to make sure all of your Windows updates are applied, especially any critical security updates. Additionally, you should check the manufacturer of your hardware devices (e.g. your graphics card or sound card) for any available driver updates. Finally, you should also look into third-party software solutions that can help with optimizing your system, such as system cleaners, anti-virus software, etc.
