The first method: use software to clean up. Open 360 Security Guard and select the "Computer Cleaning" option to clean all the following sub-options one by one (only one can be cleaned at present).

If you still feel dissatisfied, you can choose to move the system disk, open 360 security guards, and then click on the right hand side to enter the function area. If you haven't added the function of moving drive C, you can select Add to Top at the bottom, and then click Move. Just follow the requirements of the system.

The second method: use the disk program in the attachment to clean it. Click Start All Programs Accessories System Tools Disk Defragmenter to open a new dialog box, then select the disk to clean and click Defragmenter. After the cleaning is successful, "Disk cleaning is successful" will be displayed in the session status.

The third method: cleaning up my computer property. Double-click "My Computer", select drive C, right-click "Properties", open the "Properties" dialog box, select the "Disk Cleanup" button, open a dialog box, and click OK after the file type you want to clean.
