Open the 360 security guard and run the instant physical examination in the computer physical examination. At this time, 360 will automatically detect whether there are junk files or cached files in the system, and click one button to repair after physical examination.

In order to further clean up the system, 360 security guards can be used for "one-click cleaning", which can remove many useless files such as garbage, plug-ins, online traces, etc., and can also remove useless registry files, which can "slim down" the system.

Delete software that is not commonly used or unwanted in time. If you don't want to use the software, you should delete it in time, preferably forcibly, so that all programs can be completely deleted. For those that are not commonly used, you can view the Software Manager in 360- Unused Software and then clear it. For details, please refer to win7 Ultimate Edition.

After the above cleaning is completed, you can use the optimization master to carry out deep cleaning, open the optimization master, run one-click optimization first, and then run one-click cleaning. Note that in the process of one-click cleaning, don't forget to back up the registry prompted by the system, which is very important to prevent errors when cleaning the registry.

Because most systems are stored in the "C" disk, so don't install application software on the C disk, so as to avoid occupying too much system, affecting the running speed of the computer, and not conducive to the "slimming" of the system.
