About the win7 system takes up a large memory solution

win7 takes up a lot of system memory is already well known, after loading the win7 system, only the win7 system C disk takes up more than 10G. Many people want to reduce the space he occupies, but I don't know what methods can be used. In fact, many system files are unnecessary, or very sloppy! Today, I will tell you a way to halve the system memory.

Explain some of the unnecessary, very sloppy files

1. Start with the computer sleep and sleep mode

Sleep function: the computer does not take a certain time , into the low-power state, the working attitude is stored in the memory, the recovery can be restored to the original working state in 1-2 seconds. (very practical, but also the most commonly used)

Sleep function: is the working state That is, all memory information is written to the hard disk, taking 4G memory as an example, that is, writing a 4G file to the hard disk, and then shutting down. To restore the original working interface, you need to read the 4G file to the memory. (4G file reading and writing takes a lot of time, it is no less than normal boot, so the sleep function is very tasteless.)

What makes us even more shocked is that the hibernation function HIBERFIL.SYS (system file) is used Save memory state when sleeping. Will occupy the space equivalent to the memory capacity of the C drive (for example, 4G memory, this file is also 4G),

Since this is so ribbed, delete the hiberfil.sys hiberfil file!

Operation method: Run with administrator privileges (how to run as an administrator: right click on "All Programs" - "&" and "Options"", "Select" on the command prompt, select "Run as administrator" & C; Hit the following command: POWERCFG -H OFF This file is automatically deleted.

2. Smart memory

Memory plays a big role in the computer. I believe students with certain computer knowledge will understand it!

WINDOWS uses virtual memory technology (Virtual memory is to take out part of the hard disk space to act as memory. This part of the space is called virtual memory, and the virtual memory exists on the hard disk in the form of PAGEFILE.SYS.) Virtual memory is only a supplement to the lack of physical memory, so do not deify, virtual memory read and write performance (that is, hard disk read and write speed) only one-tenth of the physical memory performance, and high-frequency read and write operations on the hard disk damage Big! There may be bad sectors on the hard drive!

Under Win7 system, generally 512MB of memory, according to the actual memory usage, you can set the virtual memory to 512-768MB (the sum of memory + virtual memory is generally 256MB higher than the normal occupancy). 1GB memory, according to the actual memory usage, you can set the virtual memory to 128-512MB (the sum of memory + virtual memory is generally 256-512MB higher than the normal occupancy). Memory is 2G and above, you can generally disable virtual memory (software limited to a small amount of virtual memory, such as 128MB). Some people who do use a lot of memory, such as playing large 3D games, making large pictures, 3D modeling, etc., and receiving the system memory shortage warning, need to increase the virtual memory as appropriate.

Generally, you can disable the virtual memory first, restart the computer into safe mode (do not run a lot of programs at this time), and then defragment, reset the virtual memory after the completion, so that the page file does not contain fragments, read Write faster. Or use the PE /emergency disk to boot into the system, delete the page file, defragment the disk, and restart. Take WIN7 as an example, "Computer", right-click, properties, advanced system settings, performance settings. .., Advanced, Virtual Memory" changes. .., automatic management cancel, custom size, set, OK, exit restart.

3. Compress the system installation folder (C:/Windows/winsxs folder)

The C:/Windows/winsxs folder is the system installation folder (the chicken ribs in the chicken ribs), It can save more than 1GB of space after compression.

Operation method: first obtain the read and write permissions of the WINSXS folder (the default administrator only has read access to this folder), then select WINSXS right mouse button, regular --" advanced. ..--"Compress content to save disk space. The compression process takes 10-30 minutes, depending on the performance of the hard drive.

With the above three steps, your Win7 pure system should be less than 6G.

Although the space occupied by win 7 is very big, it is an indisputable fact. However, there are some ways to change this situation. However, everyone usually pays less attention to this problem. The method of teaching today is very easy. Go back and try it, I hope it will be useful to you.
