Remove One Operating System from Dual Boot Windows

Windows has always revolutionized itself bringing more and more possibilities for people to get their work down, earlier we used to work in Windows 98 and then Windows XP was born that simply changed everything. People are still in love with the Windows XP and after the release of its successor version called Windows Vista people usually want to use both the operating system to get entertained by both the ends. So usually they just program and install two operating system together and can use any of them one by one. This adds ability to use any version but side by side adds some heavy burden on system and kills its performance.
