It is really headache for every user that computer is running slower and slower. Except for being attack by viruses, there are other things deserved your attention. You can take some measures to free up disk space or clear up the junk.
And in this article, I would like to share my knowledge about how to improve computer speed. Here are some methods to help you as follows:

1. First it is to optimize the process of starting computer. Clicking “Start”—“Run”, type msconfig and then press “Enter”, in the tab, you can choose to cross out all the ticks except the “ctfmon”, click “Apply” and “OK”.
2. Delete all the unnecessary files or mends. Open “My Computer”—“Tools”—“Folders Options”—“View”—“Display all the Folders and Files”—“Apply”—“OK”. You can delete all the files of C: \windows\$….$ and C: \windows\i386\driver.cab.
3. Free up memory. You can release memory by choosing to the classic starting desktop instead of other ones without any background. Besides, you can delete the clip board, if you want. The classic starting desktop, background and clip board takes up much memory on the condition that your memory is really insufficient.

Moreover, you can set the virtual memory correctly. Right-click “My Computer” and then click “Properties”—“Advanced”—“Performance” to choose “Settings”—“Virtual Memory”, you can choose “Customize” in the tab. Usually, the maximal value of virtual memory is twice than that of beginning. And, you can enter into “Safe Mode” to use anti-virus software to scan the whole system.

By doing the steps above, you can not only free up space, reduce starting item, but also clear up junks useless files so as to speed up computer. If you think it is too complicated to do that manually, I recommend you to use other tool to help you.
