Why does the computer have system junk every day and must be cleaned every day

In the process of using a computer, due to the continuous addition and deletion of software and Internet access, the hard disk is prone to produce all kinds of junk files, which continue to expand, which will not only swallow up the hard disk space in vain, but also drag down the running speed of the machine and affect our work efficiency. These junk files mainly include the following categories: 1. Temporary files generated during software installation When installing many software, you must first extract your own installation files to a temporary directory (generally the temp directory under the windows folder) and then install them.

If there is a negligent design of the software or a problem with the system, when the installation is complete, these temporary files will become not "temporary" and become a pile of junk on the hard drive, many times they will be represented in *The face of the tmp appears. 2. Temporary files generated during software operation Like the installation process, some temporary exchange files are usually generated during the software operation process, and some software leaves garbage even up to hundreds of trillions after running.

For example, some programs are created when they work, such as *old、*.Backup files such as bak, backup files generated when the hard disk is checked by antivirus software or system software, etc.

3. Legacy files after software uninstallation Because most software uses dynamic link libraries (DLLs), and the design of some of them is not very mature, many software is "easy to please God, but difficult to send God". When these software are uninstalled, they often leave some folders, *...DLL file junk.

4. Temporary files generated by surfing the Internet When surfing the Internet, the browser always sends web page files to the local machine, and these cache files not only occupy disk space, but also often leak personal privacy. 5. Some infrequently used chicken rib files, such as some application software's own help or tutorial files (often used. hlp, etc.), redundant font files in the operating system, etc.

At present, the easiest way to remove junk files is to build a batch program to delete junk files (you can get it from the microcomputer administrator, it is not recommended to directly from the Internet for security reasons**), run it every once in a while, you can ensure that the system is clean and clean.

There will be garbage without interruption, and it is recommended to clean it up regularly.

If you choose to turn on"Scan", Tencent PC Manager will perform an automatic scan when the computer is completely idle (that is, when there is no operation on the computer), regularly clean up the garbage in the computer, free up disk space, help reduce the burden on the system, and make the system run briskly.

1. Use disk cleaning software to clean up the C drive, which can free up about 50M-800M space for the C drive.

2. Turn off the sleep function, enter the powercfg -h off command in the start menu to turn off hibernation, the actual size of this file is the same as the physical memory, which can free up 1-3G space for the C disk.

3. Set up virtual memory: Computer Properties > Advanced System Settings > Settings (Performance) > >Advanced Tab" Change (Virtual Memory), set the C disk to no paging file, and then set the D disk to the size of the system management, after the change, only press the "Settings" button to take effect, and finally restart to complete the setting, this file defaults to the times of the physical memory, which can release about 2-4G space for the C disk.

4. Delete the automatic backup file, run the cmd program (in "Start > Program >Attachments"), right-click and select "Run as administrator"; Then, enter rds q on the command line, prompt to confirm whether to delete the destination folder, type y and press enter. For the backup file of the system, the longer the time, the larger it becomes, and it is normal to exceed 10G. It can free up more than 3G of space for the C drive.

5. Click "Clean Trash" on the main interface of PC Manager, confirm that the relevant garbage type is checked, click "Start Scan", and then click "Clean Now", if there is any garbage that needs to be confirmed to clean up, you will confirm it and then carry out a deep cleanup to achieve a quick and safe cleanup of junk files in the computer.

It is recommended to regularly scan and clean up the computer to give the computer system a clean and fast operating environment. After cleaning more, the computer caches garbage and uses the system disk** function, the computer speed has been significantly improved, and the system disk** can effectively clean up the useless garbage of the C disk, free up disk space, and the computer runs more smoothly.

Xiaobai teaches you how to clean the C drive.

Run as Administrator

Enter "powercfg -h off" in the command box to close "Sleeping files will be compressed".

Right-click Computer on the desktop and select Properties

In the Properties that open, select Advanced System Settings

In the "System Properties" that opens, click "Settings" in the "Advanced" tab

In Performance Options, select Change under the Advanced tab

In "Virtual Memory", check "No paging files" and press "OK".

Finally, find "WinSXS" inside the "C: Windows" folder

Right-click on the file property, and in the General tab, select Advanced

Open "Advanced Properties", in Compress or Encrypt Properties, in front of "Compress content to save disk space (c)" and then hit OK.

The above is the prepared method to clean up the garbage of the C drive.

The so-called garbage includes Internet caches, operation records, log files, uninstalled software remnants, etc.1These things back.

Scattered storage on the hard disk adds disk fragmentation, reduces disk read and write efficiency, and increases the risk of file loss;

2.The operating system will retrieve some records when you are operating, speeding up the search for files, and the more records you have, the slower the retrieval will be, and the operation will be more efficient in the future.

3.Uninstalling software remnants can sometimes lead to bug associations that cause some programs to run incorrectly!

That's probably all, anyway, it's better to clean up! It's just that there's no need to ask every day, according to your own frequency of operation, clean it up after a while, and sort out the disk fragments. Everything needs to be maintained!

Must be cleaned up. Computer junk refers to caches. Temporary files. physical virtual memory, etc. It is recommended that you clean up with a bat that you do yourself. I found that none of the Guardian software was clean.

It needs to be cleaned up because when you run some applications, it will generate a lot of file junk that takes up the C drive and makes the computer run slowly.

First of all, there is also garbage abroad.

Cleaning tool du (can zhi.)

Google it); As for whether or not.

Theoretically speaking, it needs to be cleaned up, and after cleaning, it is beneficial in terms of the speed of the computer or the space of the computer, but you have to choose the right software, you can use Microsoft's MSN and 360, I have always used this.

Yes, especially the registry, otherwise the computer will become very slow in the future... It is recommended to use Windows Optimizer, I use this, it is very easy to use.

Yes, because there are many kinds of garbage, such as a redundant registry, which has a big impact on the speed of the computer.

Browsing the web every day will produce some traces, traces will store a lot of garbage, if you don't move, it will invade some system garbage, and there are some file garbage, there will be garbage you put in the trash bin, those will also be classified as computer garbage and be cleaned up, in short, there are many reasons, you can consult or look up, more garbage will affect the flow, not to return to the garbage generated every day seems to be much, in fact, even one ten-thousandth of the storage capacity can not arrive, this is a problem with the storage unit, or clean up every day, I've been doing it for half a year, but it's a big unit, don't worry, it's good to clean up regularly!

Use the computer for more! There's cache, there's traces, there's something you don't use, there's debris, and so on.

Why won't my scans stop?
