How to clean up registry garbage
Master Lu Yong.
Why is there always garbage in the registry?
It is normal. As long as the computer is running, there will always be some garbage. Don't worry too much, it won't affect the speed of the computer too much, you just need to clean it up every once in a while.
How to clean up the registry thoroughly?
Cleaning the registry manually is a troublesome and dangerous thing. Cleaning the registry with software saves a lot of worry. Among all kinds of registry cleaning software, RegClean, a free software written by Microsoft, is the first choice.
RegClean does not need to be installed, and it is not easy to make mistakes at runtime. It is small, simple and easy to use. After starting the program, it will check the registry, click a button and fix any errors found. It can register the uninstalled software in the registry, which can be said to be more thorough than the registry cleaning software written by any third party. Let's take RegClean4. 1a as an example to introduce the usage in detail.
First, run RegClean.
The way to run RegClean is very simple. Just double-click the icon of RegClean, and a dialog box of RegClean will pop up. Then it will automatically analyze the registry and check for errors in the registry. This process takes about 30 seconds to 30 minutes, the length of time mainly depends on the size of the registry and the speed of the machine.
Windows registry records all kinds of configuration information needed for the normal operation of operating system and application programs. Due to the frequent disassembly and assembly of applications and various devices, various errors may appear in the registry after running for a period of time. RegClean analyzes various settings recorded in the Windows system registry, finds out the wrong key codes, and stores these key codes in Undo. Registration documents. RegClean can then delete these key codes from the Windows registry and complete the thorough cleaning of the registry.
Second, repair the registry.
After RegClean analyzes the registry, another dialog box will pop up. Just click the "Fix Errors" button in the lower right corner of the dialog box, and RegClean will automatically fix the errors in the registry. At this point, RegClean will create an undo. REG file, the file name is "Undo puter yyyymmddhhmmss. REG”。 RegClean writes registry information to this file, which contains computer name and time information. Then delete the wrong registry key from the registry. This dialog box will prompt you about the progress of this process. It is worth noting that although RegClean can fix the errors in the registry, it cannot correct all the known errors in the registry, nor can it recover the crashed registry. Therefore, RegClean is not a panacea. At best, it can only solve some problems in the normal registry. RegClean will not deal with the incomprehensible problems.
Third, quit RegClean.
If you don't want RegClean to fix these errors before RegClean fixes them, or RegClean doesn't find any errors in the registry, you can click the Cancel button in the lower right corner of the dialog box to exit RegClean.
If RegClean has fixed the error, you can click the "Exit" button in the lower right corner of the dialog box to exit RegClean.

Why does the registry always contain junk information?
For example, the registry of Windows system is like the central system of human brain. Every operation of the computer, including changes in software and hardware, opening files and logging on the Internet, will leave traces in this central system. Moreover, this central system is different from the human brain, that is, the human brain will remember and forget, while the registry will only remember and will not forget itself. So it tends to keep a lot of useless information firmly in mind-this is the origin of spam.
