To know which programs start automatically with Windows when the computer is turned on, is important because if necessary you can disable the useless ones.
Unnecessary for the operation of the operating system and/or its security (therefore the main anti-virus excluded) such as Skype, messaging apps and other software not important.
This will lighten the loading phase of the operating system when you turn on or restart the computer, as after excluding these programs from the automatic startup Windows will take less time and resources to load and become operational.
If on Windows 7 and earlier OS, third-party software excluded, to see and disable third-party programs, you need to intervene from the “System Configuration” tool that is invoked by sending the msconfig command in the Run dialog (which in turn is called with the combination of the two Windows + R keys), on Windows 10 everything is easier.
Easier because Microsoft in the Task Manager, which is accessed quickly with the combination of the three keys Ctrl + Shift + Esc, has integrated the “Start” tab in which programs are shown that start automatically with Windows, with a lot of its impact on the startup phase of the operating system.
But since the version Windows 10 April 2018 Update, Microsoft has introduced in the settings a section dedicated to the management of programs that start automatically with the SO.
For as you can see in the above example in the figure, in Settings> Apps is now available to the “Start” in which are displayed in a sortable list them by name, “Start App” you will be able to disable or enable at will by intervening on the respective switch.
And as in the Task Manager, also in this case, but below the on/off switch, the impact of the individual apps on the Windows startup phase will also be shown: high, medium, low impact, no impact.
The greater the impact, the greater the possibility of a slowdown in the loading phase of the operating system, especially if the app and the high impact programs are more than one.
