Have you been troubled with that computer performance is declining day after day? Though you have used software to check it, computer shows that there is no virus. What is the matter? In fact, since computer has been serving for you for a period of time, there are many junks piling in the computer but you just have not realized yet.
Do not worry about that. Many causes that lead to this problem can be find in this article. What you need to do is to read it patiently and follow the steps so as to optimize Windows performance.

There is a large number of swap files in the hard disk which is prepared for putting virtual memory and many applications may often use them. In this way, system has to read the major storage at every turn. Its speed is the main cause that has influence on computer running speed. Normally, Windows system can manage virtual memory automatically according to different requirement of various applications. However, such variable changes can add excessive burden to system and reduce its working speed. As a result, you had better set the maximum and minimum values of virtual memory so as to avoid altering that too often.
As for how to do that, you can right-click “My Computer” and click “Properties”. And in the “Advanced” tab, choose “Performance” dialog box and then set “Virtual Memory”. By doing this, you can improve computer performance by limiting virtual memory correctly.

Then you should check applications and drive programs. Some programs may slow down system speed when computer starts up. If you want to check the problems in this regard, you can start your computer under “Safe Mode”. Because it is the original starting method, it should be slower than normal ways. Actually, the safe mode booting way does not have to load too many applications and drives as normal one does. But if you find it is faster rather than slower, it is probably that certain program in the system goes awry so that computer booting is so tardy. So, you need to check them in order to improve computer performance.

What is more, excessive desktop icons can reduce computer performance as well. Every time when Windows startup and display desktop, it has to find and load desktop shortcuts one by one. The more shortcuts are there, the more time are needed. Meanwhile, some anti-virus software has the function to scan system which also wastes much time. As a matter of fact, if you have opened real-time monitor function of certain software, it seems redundant to scan system when booting. You can shut down this scanning function but should be on condition that you have opened real-time monitor. And, it is suggested that you can put the seldom used icons to a specific folder or delete them without further ado.

Now, are there problems in your computer in accord with one or more descriptions in this article? If so, you should take some measures to improve computer performance; if not, you also ought to prevent those problems so as to optimize Windows performance.
