New PCs often come with unnecessary software

Clean install of Windows, which will remove all preloaded apps and give you a fresh start.

New laptops often include trial antivirus, games, shopping apps, and manufacturer utilities because the PC maker uses one factory image for many customers. Some third-party apps are included through commercial agreements, while manufacturer tools may handle driver updates, battery settings, diagnostics, and support. They are not all harmful, but too many startup items can slow the PC and clutter the Start menu.

There is no Windows setting that can prevent software already included in the manufacturer’s factory image, because it is installed before the PC is delivered. 

Start with Settings > Apps > Installed apps and uninstall obvious trialware, games, and promotional apps that are not needed. Keep items related to the touchpad, audio, graphics, battery or power management, BIOS or firmware updates, and hardware diagnostics unless their purpose is clear. For programs that may be useful but do not need to launch automatically, open Task Manager > Startup apps and disable them there. This is often enough to improve startup speed without uninstalling anything.

A clean installation of Windows from official Microsoft installation media removes most manufacturer trialware and promotional apps. Back up files first, confirm that the PC has a digital Windows licence, and download essential Wi-Fi, graphics, and chipset drivers before starting. Windows should reactivate automatically once connected to the internet. Avoid unofficial “debloat” scripts and registry cleaners, as they can remove useful Windows or manufacturer components.
