Optimizing Startup Applications Using Task Manager

In many systems, unnecessary startup applications can slow down the boot process and consume valuable resources. By disabling applications that you don't need immediately upon starting your PC, you can significantly boost your system's performance. Here's a clear step-by-step guide to help you optimize your startup applications in Windows 11:

Access Task Manager

1. Open Task Manager: Use the start menu search to find and open Task Manager.

2. Navigate to the "Startup" Tab: Here you'll find a list of applications that start with your PC.

• What does disabling startup applications in Task Manager do?

  Disabling unnecessary startup applications in Task Manager frees up hard disk resources and can speed up your PC's boot process.
