Win7 is a system released on October 22nd, 2009 10. This system is the most stable version at present. The most used system in the world (XP is no longer available, but it is still the most used in China).
Win8 is a system released on 20 12 10/October 26th, and it is the latest version of windows series. The latest official version of win8. 1 will be released in early August.
They are completely different. XP is a leap to win7. What's the difference between systems? It takes at least a few thousand words to make it clear. Let's talk briefly here.
Win7 UI looks better than xp, and hard disk management is more convenient and clear. The theme is AERO, which means transparency effect. Very good.
Win8 is an upgraded version of win7, with AERO removed. The interface is flat and concise. Win8 is not a completely upgraded version of win7, because win8 has a system similar to mobile phone interface, called metro. It can be said to be metro+win7 system. However, Metro is still a semi-finished product. The idea is that both PC and tablet can be used. PC generally does not use this system. Win8 removed the most classic start menu of windows and replaced it with a square subway-style menu, which many people are not used to, especially middle-aged and elderly people. It is difficult to find the location of the software. So win8 doesn't sell well
Currently XP? Win7 win8 is divided into 32-bit system and 64-bit system. The maximum memory support for 32-bit system is 3.25g, and the maximum memory support for 64-bit system is 128G. (Motherboard support required)
There are three versions of SP 1 SP2 SP3. Professional version is divided into family version, and most of them look at professional version.
At present, the latest version of win7 is SP 1 (only one, it is impossible to estimate SP2 in the future), which is divided into family basic version, family advanced version and professional version. Enterprise edition, flagship edition. (Home version of 64-bit memory only supports 8G. Professional edition and enterprise edition support to 128G).
Win 8 will release win8. 1 in August (restore the windows start menu, but it is not the previous menu, but there are still differences. At present, there are standard edition, professional edition and enterprise edition. (Personally, I suggest installing the Professional Edition)
Personal experience suggests that you install win8 Professional Edition system. Because the hardware requirements of win8 are lower than win7, the system response is faster than win7, and the hardware resources occupied are less than win7, so the 8. 1 version will be slimmed down. When the system is installed, it will only occupy 4G drive C (Microsoft officials say that the real situation will not be known until August), instead of almost 20G (64 bits) like win7.
