what are the big defference between windows vista and xp service pack 2

The major diffeerence is that windows vista have more interactive graphic,use lot of memory(Ram),need high processor.It only for running the operating system.You not even playing game or running a software.Xp SP2 more suitable because need low memory and processor to run it.People tend to upgrade their PC because they are many software that require a certain hardware.Like graphic card or higher ram.If you want to install windows vista from xp sp2, you need very high perfomance from your PC.

Windows Vista has many cool features that XP does not have. One of the leading new features is the startup repair feature. When windows Vista starts booting if it detects an error it automatically goes into the startup repair mode. In this mode it will be able to recover from a corrupt registry, missing windows vista files, driver issues and can even do a hard drive repair and memory test. As a computer technician I can say that windows Vista can do 80% of what I can do on startup repair. This alone makes Vista attractive. A few other great features are the search functions with in Vista right from the windows start menu. Another few others would be the Aero interface that lets shows a snap shot of the running programs as you tab between them. Another would be when browsing for programs it’s no longer all across the screen but in on a central location. The four different versions of Vista are also an advantage because business can get a more advanced version for data backup and encryption while normal home users can get the basic and premium versions that will meet their needs. Windows XP has been around for many years. Every new program still works with XP and most likely will for some time. You do not have to worry about any of your existing software not working because you are keeping the same operating system. Because Windows XP has been around the block most of the kinks have been worked out. The operating system as a whole is very stable. People are creatures of habit so not having to learn your way around a new operating system is also a plus. Many companies have proprietary software. Because of this some of those programs will not be compatible with windows Vista. Before getting Vista be sure and ask the software manufacturer you use if you need any updates or if their software supports Windows Vista.
