Nowadays, in the era when XP is about to die, with the upgrade of hardware, many friends have chosen to go to the embrace of win7. After installing the new system, many people will choose to use some optimization software or optimization cheats to achieve the purpose of making the computer run faster. There are still many friends who will follow the optimization techniques handed down in the XP era. Can these techniques be effective for Win7 systems? What happens after the application?
Speaking of optimization, many friends’ first reaction may be Optimize third-party optimization tools such as Master and Rubik's Cube. When using them, you may cause various computer problems due to misoperations or bugs in the optimization tool itself. This is what we often say is over-optimization. Over-optimization problem, what should we do? With regard to the above two questions, let's talk about the issue of Win7 optimization today.
Mission 1 Modify the boot settings, improve the boot speed of Windows 7
Run the msconfig command in Windows 7, open the configuration program in the system, and then click the "Boot" tab, and in the "advanced options" In this case, the dual-core processor user can change the number of processors from the original “1” to “2” or greater than the number of “2”. It is said that this can increase the boot speed by 20%.
Verification: After the modification, many of my friends' computers have problems with system stability. When running the program, it may cause a crash.
Comment: The normal startup of the computer is calculated according to the original default CPU core number. The number of processors in the system configuration program is set to solve some compatibility problems. The so-called number of processors is modified to 2 or Multi-core to improve operating efficiency is wrong, and can not accelerate the system optimization.
Miscellaneous 2 Virtual memory should be set to 1.5 times physical memory
Description: This technique has been around for a long time, the specific operation method is: right click "My computer", left click point "Attributes", point Select "Advanced System Settings", click "Settings" in the "Performance" button, and then select the "Advanced" tab. Click the "Change" button below. The pop-up window is virtual. Memory settings window.
Verification: With the improvement of hardware performance, 2GB and 4GB memory are already standard. If you want to install “Cheats”, set the virtual memory to 1.5 times of physical memory ——— 4GB to 12GB. This will not only speed up the computer, but slow down the system.
Comments: In the era of Win9X or XP, 256MB or 512MB of memory has been considered good, in such a small physical memory, the use of virtual memory is very high, by increasing the virtual memory to reduce "memory" The bump rate & rdquo; of course can have a certain effect. However, with the advancement of technology, memory has entered the GB era. If the virtual memory is set to a few GB, according to the hard disk of the SATA2 interface, because the read speed is about 100MB/S, the virtual memory is completely read. According to 2GB, it takes about 20 seconds, and frequent reading and writing data will result in "hard disk fragmentation". If there are more fragments, it will slow down the system speed.
Which Win7 virtual memory is set up in the end? Win7 memory usage is larger than XP and management mechanism is not the same, so can not be measured by the standards of the XP era. Win7 has priority to use physical memory, take 2GB of memory, if there is no memory management experience, and there are not many web pages opened at one time, such usage can refer to the virtual memory setting 300-1000MB this dynamic value, cope with temporary virtual Memory usage has soared. If you want to set the size of virtual memory more strictly, you need to check the specific usage of virtual memory. You can roughly add a memory counter to understand the peak memory usage in “Computer Management & Rarr; Performance & Rarr; Monitoring Tools & Rarr; Performance Counters”, and then set the virtual memory value based on this usage.
Mission 3 Save 800MB space, delete useless drivers
Cheats" Description: Enter the “C:WindowsSystem-32DriverStore” directory, delete the “FileRe-pository” folder inside, you can save 800MB. Disk space for the system "Slimming".
Verification: When deleting this directory, users need to have the appropriate permissions to operate. After deleting the directory, it has no effect on the normal operation of the system, but when using some unfamiliar Plug and Play devices, it will prompt “The device driver could not be successfully installed”, and the driver needs to be installed manually.
Comment: Compared with the small hard disk of XP era, the space of nearly 800MB is not worth mentioning for the current TB hard disk, and the plug-and-play function in Win7 is now more perfect, basically free. The trouble of the user to manually install the driver, if you delete the "FileRe-pository" folder, it is equivalent to delete the plug-and-play function of Win7, so this space saved, but a bit worthwhile.
Mission 4 Extend the life of the hard disk, periodically clear or close SuperPrefetch (formerly Prefetch read-ahead buffer file)
Description: Delete the pre-buffer file in "C:WindowsPrefetch"; enter the registry editor HKEY_LOCAL_MACHINESYSTEM CurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters”, change the key value of EnableSuperfetch to 0, disable Superfetch.
Verification: After deleting, the speed of launching a popular application is significantly slower.
Comment: The reason why this technique is useful for XP system is that in XP, Prefetch (pre-read buffer) is not easy to use, the effect is not good, and it often fails, and the hard disk indicator will always be after Prefetch is turned off. Blinking, many friends think that Win7's SuperPrefetch can not improve the working efficiency of the hard disk, but will shorten the life of the hard disk. But with the improvement of the Win7 system, today's Prefetch (which has been upgraded to SuperPrefetch) is quite easy to use. It can monitor the user's usage habits, record the time of occurrence and end of these frequent operational actions, and the time of operation. Details of the foreground and background software, etc., then when the memory has free space, you can preload a part of the file into the memory at the scheduled time. This new technology will make the whole system faster and faster. When we emptied the Super-Prefetch file, the startup rules recorded by the computer were also cleared, which would not help the program to start, but would cause Windows to re-record these rules.
Miscellaneous 5 Modify the registry to achieve lightning shutdown
Description: Open the registry editor, go to "HKEY_LOCAL_MACHINESYSTEMCurrentControlSet Control", and find the "Wait-ToKillServiceTimeOut" option on the right, the default value will be From 12000 (12 seconds) to a smaller value, you can make the shutdown speed a step faster.
Verification: The normal shutdown time of the computer (without any application) is about 12 seconds, and the key value is changed to 7000 and 0 respectively. After the setting takes effect, the test shutdown time is still about 12 seconds, basically no change. It can be seen that the cheats did not reach the legendary "Lightning Shutdown" effect.
Comment: "WaitToKillServiceTimeOut” is the time used to terminate the system service, that is, if a service is shut down for more than the specified time (the default 12 seconds) has not stopped, the system will force Stop it. However, these 12 seconds only include the time taken to shut down the system service. When we shut down, we are likely to run some applications, and the services started by each computer are different. If it is forcibly closed, it may cause The system is unstable.
From the above several XP optimization cheats or tips in the use of Windows 7, we can easily find that the technology is improving, but the method can not be copied. Because Windows 7 has a lot of functions in principle compared with XP, the most typical example is SuperPrefetch in Cheats 4. Compared with Prefetch in XP era, it has been improved a lot, so we can't Treated with an old eye.
