After a few days investigating what was wrong with my laptop, and why it was slow.
So I conclude that there are some programs that are not important in my laptop running when not needed.
Servicer is a program that continues to run on Windows systems.

There are many services that often use a lot of resources. Apparently some of these services can be discarded and can be switched off without any problems on the system we use.

Here's a list of services that can be disable  :

1. Computer Browser
2. Error Reporting Service
3. Help and Support
4. Indexing Service
5. Messenger
6. NetMeeting Remote Desktop Sharing
7. Performance Logs and Alerts
8. Protected storage
9. Remote Registry
10. Routing and Remote Access
11. Secondary Logon
12. Task Scheduler

Want to try ?
a. Click Run or WinKey + R
b. Type services.msc and Windows Services window will appear
c. Turn off services that exist in the list above by right-clicking on these services select Properties, and change the startup type to Disable
