For Windows 7 memory usage is relatively large

        Q: The Windows 7 that I was thinking about is finally installed today. After experiencing it, although it is very depressed to kill two poisons after loading, the most unreasonable thing is that the memory usage of Windows 7 is even more fierce than Vista. My 4G memory (3.5G available) takes up 900MB. Previously, XP WOW could open at least three cards. I don’t know if it occupies so much memory. Can I still achieve that effect? Or can't you open it again in the future?

A: Windows7 I also used to give me the feeling that the more you post the more memory occupied by the boot display, but also eat memory than XP Windows7, incidentally, why do not you install X64 What about the version? This can use full 4G memory, and you just have to install the virus to kill the virus so I doubt the source of your installation disk.

three open can not say, not tried, I suggest you give it a try, I guess is still possible. Don't mind this value too much, the memory management mechanism of Win7 and XP is different, you use it. Generally, the memory usage will not rise to a certain value. My memory usage keeps above 3GB for a long time. It doesn't matter. If XP uses more than 3GB of physical memory, it's more uncomfortable, so it's not the same.
