You should buy an upgrade version of Windows Vista however your computer if running XP is likely not to be powerful enough to run windows vista. You should run Microsoft Windows Vista Upgrade Advisor before upgrading as this will show you any problems your computer may have running Vista.
The standard desktop applications of Microsoft Word, Microsoft Excel and Microsoft Outlook will not run if you download them onto a Windows XP or Vista machine. It needs at least Windows 7.
Yes, everything should work except for Outlook.
They are "compatible" in the sense that many applications that run on Windows XP will run on Windows Vista.
Many applications and games written for or compatible with Windows 98 will run on Windows Vista.
You DO NOT have to wipe your hard drive or "downgrade" to run windows XP on a vista computer. Download and install Microsoft Virtual PC. its free and will allow you to run another operating system in a window of the current one you are running. You can have both!
Windows NT is part of the Microsoft Windows line of operating systems. Microsoft Windows is used to describe Microsoft's flagship OS in general while Windows NT is an outdated OS that used to run on workstations and servers. Windows 2000, XP, Vista, and 7 are all based upon Windows NT.
Vista has DX 10 when WIndows XP doesnt. While Vista was suppose to be the upgrade to XP, it had a lot of problems during the first launch and it took awhile to fix everything. Vista is suppose to run faster, and use less resources on your system. But Vista failed and Microsoft then released Windows 7 as the replacement to Vista.
depends on the computer there is a vist upgrade advisor on the Microsoft webpage here is the webpage: http://www.Microsoft.com/windows/windows-vista/get/upgrade-advisor.aspx and that will tell you if your computer is capable of whatever OS of vista you can run
There is no operating system known as "Windows 2007". The only Microsoft operating system released in 2007 was Microsoft Windows Server 2008. Microsoft Windows Vista was released earlier in 2006 and has since been superseded by Microsoft Windows 7 (released in 2009), Microsoft Windows Server 2012, Windows 8 (2012), Microsoft Windows Server 2012 R2 and now Microsoft Windows 8.1 (2013). As to how you run a C++ compiler on Microsoft Windows (regardless of the version), you first have to download or buy a compiler as well as a linker and a resource compiler. However, compilers and linkers are not generally available separately, they usually come as part of an Integrated Development Environment (IDE), which includes project management facilities and code editors. Your IDE documentation will tell you how to run the built in compiler from the command line, however in an IDE this is seldom necessary as all compilation and linking can be achieved from within the IDE itself.
