DISABLE AUTO-START APPS ON START UP

Here are two ways on how to disable apps on start-up. By the way Start up apps are those applications/softwares that run when windows starts. These applications may lengthen the period of startup. So the more applications that run on startup. The longer a startup.
So you must atleast disable those startup applications which are unecessary.

1.Click on the Start Button and key in msconfig and hit Enter.

2. Click on the Startup tab.

3. Remove the check next to any items that you do not want to startup and click OK.

*Disabling auto-start applications with Windows Defender

1. Click on the Start Button and type in Windows Defender and hit Enter.

2. Click on the Tools from the top menu bar.

3. Click on Software Explorer.

4. Hit Show for All Users.
