Yes ofcourse, Windows Vista is upgraded version of Windows XP. Obviously it can run Windows XP applications.
Many applications and games written for or compatible with Windows 98 will run on Windows Vista.
Most programs that run on Windows XP will also run on Windows Vista.
Yes.
No obv not.

It can be found under All programs It can be found in the Start Menu
Backwards-compatibility is already built into Windows Vista and Windows 7. There's nothing that you can install to aid in compatibility if running the program in Comaptibility Mode does not work.
Many DOS applications simply will not run under Windows Vista, and none under the 64-bit version. Making the NTVDM support DOS programs in Vista was an extremely low priority, since very few people actually run DOS programs anymore. You can use QBasic and other DOS programs on Vista (even the 64-bit version) by using an emulator known as DOSBox.

You can use Windows Defender to disable programs that run at startup, or using System Configuration.
Windows Vista can already run most XP applications, with no need for any additional software.
Go to start, and then click all programs and it will appear with a list of programs installed on your computer. Then search for a folder called accessories and inside that there is the Run program. Hope that helps
