Slim down for your win7

We will find that Windows 7 is Between XP and Vista, but for some people, we still want to minimize Windows 7. The following three ideas will help you get your wish. 1. Deleting the hibernation file hiberfil. sys many people often fail to figure out what the computer sleep is. In fact, the computer has two low-power running states: sleep and sleep. Our computer often uses the sleep function, that is, the computer does not need a certain period of time to enter the low power consumption state, the work attitude is saved in the memory, the recovery can be restored to the original working state within 1-2 seconds. This function is very practical and most commonly used. However, sleep writes all the memory information in the working state to the hard disk. Taking 4 GB memory as an example, 4 GB files need to be written to the hard disk before shutdown. The original working interface can be restored only when 4G files are read to the memory after the boot is restored. 4G File Reading and Writing takes a lot of time, no less than normal boot, so the sleep function is not practical now. The dormant HIBERFIL. SYS file is used to save the memory status during sleep. Disk C occupies space equivalent to the memory capacity (taking 4 GB of memory as an example, this file is also 4 GB), so you can delete it without affecting your use. Operation Method: Run CMD as an administrator and run POWERCFG-h off to automatically delete the file. (How to run as Administrator: Right-click "All Programs"> "attachments"> "command prompt" and select "Run as administrator".) 2. Compress C: windows winsxs folder is the system installation folder, which is not used for most of the time. After compression, it can save more than 1 GB of disk space. Method: first obtain the read and write permissions of the WINSXS folder (the default Administrator only has the read permission for this folder), and then right-click WINSXS, General --> advanced... --> compress the content to save disk space. The compression process takes 10-30 minutes, depending on the hard disk performance. 3. Correctly Setting the virtual memory to exist in the computer is very useful. All running programs in the computer need the memory. If the program is large or large, the memory will be exhausted. To solve this problem, WINDOWS uses the virtual memory technology, that is, taking out some hard disk space for memory usage. This part of space is called virtual memory, the format of existence on the virtual disk is PAGEFILE. SYS. Virtual Memory is only a supplement to insufficient physical memory, so do not turn it down. The read/write performance of the virtual memory (that is, the read/write speed of the hard disk) is only a fraction of the physical memory performance, in addition, high-frequency read/write operations are very damaging to the hard disk! Hard drive bad sectors are easy to appear! If you can, you don't need it. If you can use less, you can use less! The principle is to use + leave a small margin. Generally, 512 MB of memory is used in Windows 7 7. Based on the actual memory usage, you can set the virtual memory to 768-MB (the sum of memory + virtual memory is generally MB higher than normal usage ). 1 GB memory, depending on the actual memory usage, you can set the virtual memory to 128-512 MB (the sum of memory + virtual memory is generally-MB higher than normal ). If the memory is 2 GB or above, virtual memory can be disabled (a small amount of virtual memory, such as 128 MB, can be set with software restrictions ). Some people who actually use a large amount of memory, such as playing large 3D games, making large images, 3D modeling, and receiving a warning about insufficient system memory, 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 large number of programs at this time), then perform fragment, and then reset the virtual memory so that the page files do not contain fragments, faster reading and writing. Or use the PE/emergency drive to boot the system, delete the page files, sort out the disk, and restart the system. Take WIN7 as an example. Right-click "computer", select Properties, advanced system settings, and choose performance> Settings ..., advanced, virtual memory> change ..., automatic Management cancellation, custom size, settings, OK, and restart.
