Win7 quick cleaning system garbage usage and skills

In the process of using the computer, there are always many system garbage data files. These system garbage data sometimes leaks our privacy and causes insecurity. Of course, too many junk files sometimes affect the system speed. Of course, the garbage must be cleaned up. What should we do?
Today we share with you the method of manually cleaning up garbage by Win7.
As we all know, there are two main places where Windows7 junk files are stored:
One is in the folder
> One is stored in the registry.
First, the garbage in the folder is: (assuming Windows is installed in the C drive, such as replacing letters in other partitions)
1, & ldquo; garbage in my document, placed in C: WindowsRecent In the folder;
2, install the program, the temporary file generated when editing the file is placed in the c:windowstemp folder;
3, the thing thrown into the trash when deleting the file is in the C:RECYCLED folder (hidden folder);
4, when you browse the website, Windows will keep the pages you have seen in the C:WINDOWSHistory and C:WindowsTemporary Internet Files folders;
5, once logged in Information, Microsoft will also retain cookies, which are stored in C: WINDOWSCookies.
Second, the garbage in the registry:
In the Windows system, the registry is a complex information database that records the settings and locations of 32-bit drivers.
When the operating system needs to access the hardware device, it uses the driver, and even the device is a BIOS supported device.
No BIOS support The driver must be installed when the device is installed. 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 to device records. They cannot be used.
Long-term use of Windows system, the registry is frequently read, always leaving a variety of residual information, such as missing shared DLL files, unused file extensions, type libraries, fonts, applications Program paths, help files, and obsolete software are all in the registry!
But we better not to delete these residuals manually, so as to avoid system errors.
It is recommended to use professional cleaning tools to scan and clean.
Clean up system garbage is one of the homework that every Microsoft operating system user must do.
Since it is homework, there will be a difference between someone doing well and someone doing poorly.
