Yes.
Many applications and games written for or compatible with Windows 98 will run on Windows Vista.
I doubt there's any way to really quantify "worst." Windows NT running on non-Intel architectures could only run certain MS-DOS programs under emulation, and 64-bit versions Windows XP/Vista/7 cannot run 16-bit applications at all. 32-bit versions of Windows Vista and 7 can run 16-bit Windows applications, but MS-DOS programs are limited to text mode.
Yes ofcourse, Windows Vista is upgraded version of Windows XP. Obviously it can run Windows XP applications.
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.
Most programs that run on Windows XP will also run on Windows Vista.
No obv not.
Yes.
I previously posted that Organizer does not run under Vista, but that answer was incomplete and misleading. It turns out that it does work on the 32-bit Vista platform, but not on the 64-bit Vista that I'm running. Sorry for the confuion.
Yes, it can. But sometimes it doesn't work as it is supposed to. In such cases you have to check Microsoft website the game author for updates and possible solutions.
Yes it works fine.
No you can't because 64-bit won't run on an x86 (32-bit) PC. You have to have the x86 version.
