Question 2: How to clean up the virtual memory? Several solutions to the shortage of virtual memory in Windows Q;
I often hear people say virtual memory. What is virtual memory? Why does my computer always prompt that the virtual memory is too low after a period of use? Is it only by reinstalling the operating system that the problem can be solved?
A: Windows operating system uses virtual memory to dynamically manage runtime swap files. In order to provide more memory capacity than the actual physical memory, the Windows operating system occupies a part of the hard disk as virtual memory. When the CPU needs it, it will read the data in the memory first. When the running program capacity exceeds the memory capacity, the Windows operating system will write the data that needs temporary storage to the hard disk. Therefore, the memory size of the computer is equal to the actual physical memory capacity plus the size of the "paging file" (that is, the swap file). If necessary, the paging file will use all available space on the hard disk.
If your system's virtual memory is too low, you can right-click My Computer and select Properties → Advanced → Performance Settings → Advanced → Open Virtual Memory Settings. You can reset the maximum and minimum values, change the storage location of virtual memory according to the double value of 1.5~2 of physical memory, and set it to other large-capacity hard disk partitions, so that the virtual memory of the system has enough space.
There are three ways to solve the shortage of virtual memory:
1. The user-defined virtual content (automatic by default) is too small, so it can be resized.
2. The spare capacity of the disk where the system is located (usually disk C) is too small, but the running program is very large, and the virtual memory is generally created in the system disk directory by default. We can usually delete some unused programs, move useful files such as documents, pictures and downloaded materials to other disks, clean up the "recycle bin" to keep the space of the system disk above 1GB, or define virtual memory to other drive letters with more free space.
3. The spare capacity of the system disk is not small, but frequent installation and downloading of software, repeated deletion, resulting in excessive file fragmentation, is also one of the reasons for the lack of virtual memory. Virtual memory requires continuous space. Although the spare capacity of the disk is large, there is no continuous space, so it is impossible to establish a virtual memory area. You can use Disk Utility to defragment.
Nine reasons and solutions of insufficient virtual memory: the system prompts nine reasons and solutions of "insufficient memory".
First of all, the clipboard takes up too much memory.
In fact, the clipboard is a temporary area in memory. When you use the "Copy" or "Cut" command in a program, Windows will temporarily store the copied or cut content and its format on the clipboard for "pasting". If the picture is stored in the current clipboard, the clipboard will take up a lot of memory. At this point, please follow the following steps to clear the contents of the clipboard and release the memory resources it occupies:
1. Click Start, point to programs or all programs, point to attachments, point to system tools, and then click Clipboard Viewer to open the Clipboard Viewer window. 2. On the Edit menu, click Delete. 3. Close the Clipboard Viewer window.
In order to distinguish it from the multiple clipboards provided by Microsoft Office programs, the clipboard mentioned above is usually called the system clipboard. If you are using a Microsoft of Office program and use its multi-clipboard function, you should clear the items on the Office clipboard by clicking Clear All or Clear Clipboard on the office clipboard task pane (OfficeXP) or toolbar (Office2000). When you empty the Office clipboard, the system clipboard will also be emptied.
Second, there are too many open procedures.
If there are too many documents open or too many programs running at the same time, there is not enough memory to run other programs. At this time, for multi-document interface (MDl) programs, such as Word, Excel and so on. , please close all documents except the current document, and exit the programs that are not currently used, and then you may be able to continue the task interrupted by "insufficient memory".
Third, restart the computer.
If you just quit the program without restarting the computer, the program may not be able to return memory resources to the system. Please restart your computer to release system data ... >>
Question 3: How to clean up the virtual memory when it is full? When you are playing a game in full swing, or surfing in the * * * and opening multiple windows, your system will always prompt you, as shown in the right picture. The machine is as slow as a snail at this time, and the good mood just now is gone. The simple setting of virtual memory has aroused the interest of many novice friends, which they often encounter. What is the function of virtual memory? How much should I set? This article will introduce in detail. The following steps take Windows XP operating system as an example.
Create a "standard room" for virtual memory
When the system is running, the required instructions and data should be transferred from external memory (such as hard disk, floppy disk, CD-ROM, etc.). ) into the memory, and then the CPU reads instructions or data from the memory for operation, and stores the operation results in the memory. Memory plays the role of "setter" When running a program requires a lot of data and takes up a lot of memory, the memory warehouse will be "filled", and there will always be some data in this "warehouse" that has not been stored for the time being, so we should "invite" this part of "inert" data to make room for "active" data. At this time, it is necessary to create another backup "warehouse" to store "inert" data. Because of the large space on the hard disk, Microsoft Windows operating system chooses the address of the backup "warehouse" on the hard disk, and this backup "warehouse" is virtual memory. By default, virtual memory is saved in the system partition of the hard disk as a swap file named Pagefile.sys.
Manually set virtual memory
By default, the system is allowed to manage virtual memory. However, the default management mode of the system is usually conservative, which will cause the page file to be discontinuous when it is automatically adjusted, reducing the reading and writing efficiency and working efficiency. Therefore, the prompt of "insufficient memory" often appears. Let's set it ourselves.
① Right-click the "My Computer" icon on the desktop and select the "Properties" option in the right-click menu to open the "System Properties" window. Click the "Advanced" tab in the window to open the advanced settings dialog box (figure1);
② Click the Settings button in the Performance area and select the Advanced tab in the Performance Options window to open its dialog box.
③ You can see the area about virtual memory in this dialog box, and click the "Change" button to enter the setting window of "Virtual Memory". Select a partition with large free capacity, check the check box before "User-defined size", fill in the specific values in the columns of "Initial size" and "Maximum value", then click the "Settings → OK" button in turn (Figure 2), and finally restart the computer to make the virtual memory settings take effect.
Question 4: How does Win10 release the space occupied by virtual memory? At present, the default virtual memory occupied by win 10 system is not large, that is, it occupies 2-3 G of the system disk.
It's easy to turn it off if you want.
Right-click this computer icon on the desktop and select Properties.
Select Advanced System Settings at the top left of the system interface.
Advanced performance settings in system properties.
Select the Advanced tab in the New dialog box.
The second is virtual memory.
Just choose change. 、
It is recommended that you turn off the virtual memory on the system disk (that is, choose no paging size), and then turn on the virtual memory on other disks, because some software requires that the virtual memory must be turned on even if it is useless, otherwise some software may report an error.
Question 5: How to release the memory space when the computer is out of memory? What memory do you mean, running memory or disk space?
Running memory: computer-properties-advanced system settings-advanced (performance)-set your virtual memory size after entering.
Disk space; Any garbage security guard can delete this, so don't delete the movies you have seen, which will reduce a lot of space.
Question 6: How to release the disk occupied by virtual memory! Use security software.
Slimming system disk
Virtual memory can be deleted.
Question 7: How to release virtual memory when the computer is getting slower and slower? In order to avoid the shortage of system space, you can set the computer to automatically clean up the virtual memory when it is turned off again. The method of clearing the virtual memory page file when shutting down is simple, but it will definitely help your computer run:
First, click Start → Control Panel to open the control panel.
Then, select Administrative Tools → Local Security Policy to open the local security settings window.
Double-click "Local Policy" in the "Security Settings" column, select "Security Options", and in the space on the right, find and double-click the "Close and clean the virtual memory page file" option. In the dialog box that pops up below, set this item to "Enabled", and finally click "OK".
If you can, please choose the satisfactory answer.
Question 8: How to clean up virtual memory quickly? Create a new text document on the desktop and rename it "Clear Virtual Memory". Bat ".
Right-click to edit and copy the following text:
Title= Clean up virtual memory files. ...
del/a/f/q % home drive % \ pagefile . sys
cls
Just close and save the file. When you want to use it, it will automatically clean up the virtual memory when you click it, which is very convenient and practical.
Question 9: How to free physical memory? My computer is the same as yours. I have bought it for two years. Teacher Lu Chang can optimize memory to clean up garbage, input system configuration in computer operation, and prohibit unnecessary software startup in startup items. Under normal circumstances, win7 can occupy about 1G of memory, and it is normal that the physical memory is about 50% after booting.
Question 10: How to clear cache garbage in virtual memory? 360 security guards, or master Lu, both will do. Master Lu can also test the performance of various parts of the machine.
