The computer has been used for a long time, and the operation speed is slow. It teaches you how to clear the garbage in the computer.

1. Click "start">"Program"Attachment", click "System Tools", click "Clean up disk", select disk C, confirm, select all "ports", and then confirm; click "disk fragmentation program" in "System Tools", which takes a long time. Please wait. Some programs have been deleted, but not completely deleted. The installation information is still retained in the computer's registry. If you do not delete these useless information in time, the Registry will become larger and larger after a long time, affects the system performance. You can use the following methods to completely delete it.

2. After multiple installation and reverse installation, the system retains a lot of useless DLL files and should delete them. Click the Start Menu, click Run, and type Regedit in the text box to open the registry editor window, open the HKEY_LOCAL_MACHINE \ SOFTWARE \ Micosoft \ Windows \ CurrentVersion \ shareddlls branch in sequence. On the right side of the dialog box, there is a number in the brackets behind the key value data. If the number is 0, the DLL file has become junk and deleted.

3. When uninstalling unwanted programs, select "Add/delete programs" in "Control Panel" to confirm deletion. This is the complete method of deletion. The deletion effect in disk partitions is poor, and sometimes some programs cannot be deleted. Even if the "Add/delete programs" in the "control panel" is uninstalled, some programs still have the names of these programs in the Registry and become spam. Open the registry editor window using the preceding method, and open the HKEY_LOCAL_MACHINE \ SOFTWARE \ Micosoft \ Windows \ CurrentVersion \ Uninstall branch in sequence. Each folder under the uninstall primary key corresponds to an application. When you open a folder, you can see the content of the program's reverse installation, including the program name displayname and uninstallstring. Find the program name you have deleted, right-click its upper-layer folder, and select "delete ".

4. Some programs that can run directly in windows without the uninstall program or without installation (copied to the computer), such as many small games. The Registry records the program running parameters. If you delete such a program, you still need to delete the useless information in the registry. Open the HKEY_CURRENT_USER \ Software branch in sequence. Find the folder of the corresponding program from each sub-key and delete it. You can also click "edit" | "Search" to find the sub-keys or key-value items that contain the software information one by one to thoroughly clean up.
