1. Delete hibernation file.
"Run as administrator, all programs → attachments → command prompt", right-click and select "Run as administrator".
After entering the command prompt, manually enter "powercfg -h off", and Jupiter people will know what this is for. ...
(The file is a hidden system file under the root directory of drive C, and the size of the hidden hiberfil.sys file is exactly the same as its own physical memory. The method of safely deleting the hibernation file is as follows: First, all programs-attachments-administrators open the command prompt, enter (paste directly), powercfg -h off, and press enter, that is, delete directly. The second is to run disk cleanup. If there are hibernation files, check and clear them. )
2. Turn off system protection
Right-click Computer Properties-Advanced Management Settings-System Protection
3. Transfer virtual memory
Right-click Computer Properties-Advanced Management Settings-Advanced-Performance-Settings-Advanced-Change.
4. Transfer "Users' Files"
Double-click the Administrator folder on the desktop, and it is suggested to transfer four system folders.
Desktop, Favorites, My Desktop, My Documents.
Right-click the project property to transfer-location x: \ users \ administrator.
Weight loss strategy (deleting files without deleting functions simplifies the optimization system and simplifies the optimization performance)
Don't waste saliva, just put the valid address in.
1.c: \ Windows \ Web \ Wall * * * (Windows wallpaper) recommended for transfer.
2.c:\ Windows \ System32 \ DriverStore \ File Repository。
Search input ATI *. INF (14.6m) NV *INF (94.9m) (A card users delete N, N card users delete A,-|||)
Search and enter mdm*. Inf (2 1.6M) Delete things that are no longer used.
Search input prn*. Inf (78 1M) prn starts all printer drivers, which I believe most people don't need.
Even if you have a printer, you will buy one with a drive. Delete it!
Note: prnms001.INF/prnoc001.INF/prnms002.inf is not a printer driver, so it is recommended to keep it!
3.C: \ Boot (13.3m), Windows startup interfaces in different languages can be deleted except zh-CN.
4. c: \ perflogs \ system \ diagnostics (9.39m) This is the test record file deleted after the system test.
5.C: \ Windows \ Download and install some programs (Dreamweaver…… ........................................).
When installing, the installation files will be extracted into this folder. It can be safely deleted. Tens of meters to hundreds of meters.
6.C: \ 6。 C:\Windows\Help (66.7M) Click all ... I believe that no comrade Xiaobai is watching this. ...
7.C: \ Windows \ IME \ IMES C5, it's up to you. Anyway, I use a third-party input method.
Microsoft pinyin input method (74.5M) can be left.
C:\Windows\IME\IMEJP 10
Japanese input method (37.8M) has been deleted.
C:\Windows\IME\imekr8
Korean input method (2.86M) deleted.
C:\Windows\IME\IMETC 10
Delete traditional Chinese input method (2 1.6M)
C: \ Windows \ System32 \ IME will also have these input methods! Delete method as above.

Save hard disk space -Win 7 weight loss strategy
After the release of win7RTM, many friends installed windows7 system, but windows7 system is not as slim as winxp. The newly installed windows7 system takes up more than 10G of hard disk space without installing any software. The author has studied Microsoft's system and found that there are many unnecessary files in the system disk, and deleting them in time has no effect on the use of the system. Next, I will teach you to lose weight on win7.
First, win7 loses weight, deleting the hibernation file hiberfil.sys
I believe many people still don't know what computer hibernation is after using the computer for so long. In fact, computers have two ways to save electricity: hibernation and sleep. The frequently used function is the sleep function. When the computer is not used for a period of time, it enters the sleep function, that is, after a certain period of time, the computer enters the low power consumption state, and the working posture is stored in the memory. When restoring, it can be restored to the original working state within 1-2 seconds. This function is very practical and most commonly used. However, hibernation is to write the working state, that is, all memory information, to the hard disk. Take 4G memory as an example, that is, write 4G files to the hard disk first, and then turn it off. Boot recovery requires reading 4G files into memory and restoring the original working interface. It takes a lot of time to read and write 4G files, which is no less than normal startup, so the hibernation function is not practical now. Heberfield SYS file is used to save the memory state during sleep. It will take up the space equivalent to the memory capacity of drive C (taking 4G memory as an example, this file is 4G), so it can be completely deleted without affecting everyone's use.
Delete method: run CMD with administrator privileges and type the following command: POWERCFG -H OFF automatically deletes files.
(PS: how to run as an administrator: right-click all programs-> accessories-> command prompt and select "run as an administrator")
Second, the correct setting of win7 virtual memory to lose weight
Memory plays a great role in the computer. All running programs in the computer need memory. If the executed program is large or many, it will lead to memory exhaustion. In order to solve this problem, WINDOWS uses virtual memory technology, that is, a part of the hard disk space is used as memory, which is called virtual memory, and the virtual memory exists on the hard disk in the form of page files. Virtual memory is only a supplement to the lack of physical memory, so don't deify it. The reading and writing performance of virtual memory (that is, the reading and writing speed of hard disk) is only a few tenths of that of physical memory, and high-frequency reading and writing operations are very harmful to hard disk! Hard disk bad track is easy to happen! Don't use it if you can, and use it less if you can! The principle is enough+leave a small margin.
In Win7 system environment, the memory is generally 5 12MB. According to the actual memory usage, the virtual memory can be set to 5 12-768MB (the sum of memory+virtual memory is generally 256MB higher than normal usage). 1GB memory, according to the actual usage of memory, you can set the virtual memory as 128-5 12MB (the sum of memory+virtual memory is generally 256-5 12MB higher than the normal usage). If the memory is more than 2G, you can generally disable virtual memory (if there are software restrictions, you can set 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 received a warning that the system memory is insufficient, and virtual memory needs to be increased appropriately.
Generally, you can disable the virtual memory first, restart the computer to enter safe mode (don't run many programs at this time), then defragment it, and reset the virtual memory after completion, so that the page file can be read and written faster without fragmentation. Or use PE/ emergency disk to boot into the system, delete the page file, tidy up the disk, and restart. Take WIN7 as an example, right-click "computer", properties, advanced system settings, performance > settings ..., advanced, virtual memory > change ..., automatically manage cancellation, customize size, set, confirm, exit and restart.
Third, win7 slimming compressed C:\Windows\winsxs folder
This folder is the system installation folder and is not used most of the time. After compression, you can save more than 1GB of disk space. Methods: First, get the read and write permission of the WINSXS folder (by default, the administrator only has the read permission of this folder), then select WINSXS, click the right mouse button, and compress the contents in General-> Advanced ...-> to save disk space. The compression process takes 10-30 minutes, depending on the performance of the hard disk.
Through the above three steps, your Win7 pure system should only account for about 6G.
