The optimized system operates better, and the performance and fluency can be greatly improved. What about the memory? Can memory also be optimized? The answer is yes. The following is my tutorial on win7 system physical memory optimization. I hope it will be helpful to you!
1. First of all, let's open the registry editor window of the computer. The method is very simple. At the same time, press Win + R to open the running window of the computer, then enter regedit and click enter to open the registry editor window.
2. In the registry editor window, we expand HKEY in the menu on the left_ LOCAL_ MACHINE\System\CurrentControlSet\Control\Session Manager\MomoryManagement。
3. First, we find the file largesystemcache and double-click it. In the pop-up window, we can modify it to 5.
4. Next, we find the file secondleveldatacache, which is the secondary cache of CPU. The default value data should be 256. Let's modify it to 512.
5. The last one that needs to be modified is the file disablepagingexecutive. Let's change the numerical data to 1.
① close the system restore point (function) to release unnecessary hard disk space. The operation steps are as follows: computer → properties → there is a system protection in the upper left corner, click → click on the protected disk, and then click the configuration below → enter the submenu and click to close the system protection. To be honest, this function is still weak, because there is not enough space. If friends who have high requirements for system stability can use the backup and restore in the control panel, the function is powerful, which is different from the principle of XP
② turn off the Automatic Defragmentation of the hard disk and cancel the Automatic Defragmentation of the hard disk, which has improved the performance of the hard disk. Some friends often say that my computer configuration is not bad. Why is it still a card to run Vista and win7? This is the real reason. Although the CPU and GPU of the computer are powerful, the performance of the hard disk will not be improved much. Defragmentation will seriously restrict the performance of the hard disk, So just sort it out regularly. Operation method: turn on the computer → click a hard disk partition casually → properties → tools → defragmentation → defragment immediately → enable the plan → remove the hook according to the plan to download Windows 7 system. In this way, the performance of the hard disk is improved a lot, and the phenomenon of chuck will not be encountered in routine operation
③ close windows provider, which is the anti spyware software of win7 and vista. To tell you the truth, this software is quite useless. Careful friends will find that the memory usage of a newly installed win7 system is about 750mb. After installing an anti-virus software, the memory usage is probably more than one GB. Now most people still have 2G memory, and the remaining memory is not enough, So we have to close it, choose a better anti-virus software (function) to release unnecessary memory operation, and open the control panel → click the windows Developer Icon is a wall (it is specially explained here that some friends will say that there is no icon in it. Note that there is a viewing method near the closing window, and change the category to a large icon) → enter and click to remove all the hooks in it, At this time, it is found that the memory usage is about 450MB.
At this time, the computer performance will improve a lot.
About win7 administrator automatic login settings
Some programs must be clicked once. It is very troublesome to run as an administrator, but some automatic mounts will not only run through the administrator, but also have many problems after automatic operation, which is very inconvenient. You can log in as an administrator by default through the following two methods, Open the command prompt (in the program → attachment, remember to run in the administrator mode, not directly. Right click the command prompt to run as an administrator. If you are an administrator, you will see such a prompt. See an administrator in the upper left corner, and enter netuser administrator / active: Yes
If the input is correct, you will be prompted to complete the command successfully, and then log out. At this time, you will have two accounts to choose, one is set by yourself, and the other is the administrator account. You can log in by selecting the administrator account. However, if you just do so, you will be asked to choose once every time you start up in the future, which is a little troublesome, Open the command prompt and enter the following command control userpasswords2 to get the following dialog box
Click on the administrator, and then remove the hook above that you must enter the user name and password to use this machine. Just click on the application
