Fast Win7 system garbage also system a pure

A, the computer generated temporary data, history and so on spam data to prevent in the following folder; (default win7 system disk letter C)

1, "My Documents" in the garbage, placed in the C:windowsrecent folder, directly delete the useless data;

2, installation procedures, editing files generated temporary files placed in the C:windowstemp folder, directly to delete and will not affect the operation of the program itself;

3, delete the file thrown into the trash in the C:recycled folder, this folder is a hidden folder, usually empty the Recycle Bin, or delete the file using the shortcut "Shift key +delete", permanently delete the file, so that the deleted data will not be placed in the Recycle Bin, Save the operation to empty the Recycle Bin, of course, the data deleted is also more cumbersome to recover;

4, when you surf the Web site, Windows will be in the c:windowshistory and c:windowstemporary Internet Files folder to protect the Web pages you have seen and access records, and so some information, directly deleted;

5, once logged on the information, Microsoft will also retain cookies, these are stored in the c:windowscookies, direct AH delete can be.

Normally, if we use a computer to load and unload the software or change the settings, because some operations perform registry writes, these operations will also generate some garbage data in the registry and need to be cleaned up; (a registry operation is recommended for a registry backup to avoid faulty operating system errors.) You can enter ' regedit ' return in the Run window or the Start menu search box, and the Registry Editor will be opened.

The registry is an important database in Microsoft's Windows system for storing system and application setup information. The Win7 system requires access to hardware devices, which use drivers and even devices that are supported by a BIOS. No BIOS support device installation must need to drive, this driver is independent of the operating system, but the operating system needs to know where to find them, file name, version number, other settings and information, no registry of the device records, they can not be used.

The computer is used for a long time over time, the registry is often read more frequently, and will be left with a wide variety of information, such as missing shared DLL files, unused file extensions, type libraries, fonts, application paths, help files, discarded software, and so on. Some useless information will remain in the Register! However, if it is not very professional, we'd better not manually delete the residue information, so as to avoid accidental deletion caused system problems. It is recommended that you use a professional cleaning tool to scan and clean. For example 360, the computer housekeeper, Jinshan Guardian and so on many computer optimization software will provide the corresponding service.
