The Windows 10 operating system utilizes a variety of measures in order to track your app launches so that it can boost both your start and search results. It can personalize the start menu based on the apps that you use the most on the Start menu as well as the search results. This way, the App Launch Tracking is definitely useful especially when you want to access your favorite and frequently used apps quickly in the Start menu and search results on your Windows 10 computer.
On the other hand, Windows 10 provides users with the ability to control their privacy settings in order to protect the privacy of users. Windows 10 users can either opt to enable the app launch tracking to improve the start menu and search menu or opt to disable the app launch tracking in order to prevent the Windows operating system from tracking that you open if you really value your privacy that much. Whichever setting you prefer, you need to change the privacy control settings as well as make some tweaks in the Windows Registry in order to turn on or turn off the app launch tracking feature.
Note: Keep in mind that when you disable the app launch tracking feature, the “Show most used app” setting will either be grayed out or labeled as “Disable” on your Windows 10 computer. Thus, if you want to keep viewing the most used apps, just re-enable the app launch tracking feature if you have disabled it.
