Share the xp_sp2 service details and Optimization
Xp_sp2 service details and Optimization
I personally think that XP optimization only starts from the service and is the true optimization. There are some methods circulating on the internet, and I think it is a nonsense. For example: Modify the second-level cache and remove 20% of QoS, to speed up the display speed of menus, this is either useless or confusing. As for how to close the visual effect, I tried it multiple times, so the resource usage is very small and there is no need to close it, I use XP because it looks nice. Why don't I get it? There is "regsvr32/u zipfldr. DLL ------ cancel zip support ", you can try
, Run this command, restart, and find the ZIP file on the hard disk. Although the image is unrecognizable to Windows, double-click the file to open it and change it to the icon, this command can be used to load zip without being started, but cannot be canceled. It should be correct that after the command is restarted, install WinRAR immediately, in this way, the zip support will not be loaded again when the ZIP file is running. In fact, there are still a lot of optimization methods on the Internet that are useless. I hope you can tell us the absolute and effective optimization methods that have been proven in practice and let the optimization go to the end! First, make sure that the optimization scheme mentioned here is set based on my computer and network environment (for example, no printer or optical fiber network). Each person can set it based on his or her own situation, you are welcome to propose amendments.
First, I changed some settings based on the default service xp_sp2:
02. Application Layer Gateway Service

The optimized sample can save about 20 mb of memory and significantly improve the running speed (because many
Is not loaded ). I have tried the best optimization (keep the Internet environment) and can be optimized to 35 MB left.
