Nobody likes slow performance of their computer and in fact it feels more irritating if you have some good configuration system but still are facing the slow speed of the system. There are many steps that can be taken to reduce the impact of the problem as listed here.
Well apart from trying the steps what you can do is try using this tool called StartUpLite. The tool is developed by the popular Malwarebytes Anti Malware team. StartUpLite is a lightweight and simple to use application that allows you to speed up your system startup, safely and efficiently. The program allows you to disable or remove unnecessary startup entries from your computer. By using StartUpLite, you can dramatically help shorten your startup time with only a few clicks of the mouse.
I have used the Malwarebytes Anti Malware tool and was so impressed by its performance that I always recommend this to everyone. Similarly this tool is also worth a try and should be used if you are facing the slow speed of your system that used to be fast once.
StartUpLite is a free and small application that is supported on all versions of Windows OS.
