Microsoft Windows is a popular family of operating systems.
The Command Prompt is the command-line interpreter provided by Microsoft for Windows systems and is the not-as-powerful equivalent of the shell in Linux and Mac OS. It can be accessed by going to 'run' and typing 'cmd.exe' or by running a 'Batch file'.
The Task Manager is an application built into Windows that allows for the managing running processes as-well as providing information about computer performance. It can be accessed by pressing Ctrl+Alt+Delete and choosing Task Manager or you can press Ctrl+⇧ Shift+Esc to open it directly.
The Device Manager is an application built into Windows that allows for the management of device drivers. It can be accessed from the Control Panel.
The Registry Editor allows users to edit the Windows registry. It can be accessed by going to 'run' and typing 'Regedit.exe'.
A Blue Screen of Death (a.k.a BSOD or Bluescreen) is an error screen that Windows produces when it encounters an error that it cannot recover from.
DirectX is a collection of APIs for Windows that allows programs to interact directly with hardware.
The .NET Framework is a software framework for Windows that is required for games built in .NET-aware languages (such as C# or Visual Basic), including those that use XNA. Different games may require different versions of .NET Framework. A list with download links to all versions may be found on MSDN. Windows 8 and 10 users may want to read this.
DLL stands for "Dynamic Link Library". DLL files (.dll) are Windows exclusive library files containing code and data that can be used over several applications.
While they can save time for developers, these files can cause problems for the end-user (commonly referred to as "DLL Hell").
Previous Windows of versions included a compatible version of secdrv.sys for the Macrovision safedisc DRM, but Windows 10 does not, rendering games requiring SafeDisc unplayable. According to a Microsoft representative "Safedisc is not supported on Windows 10" and people will have to wait for Macrovision to come out with an updated secdrv.sys.

Note: Normally Windows 8+ automatically detects if an application needs DirectPlay or other legacy components when it launches and prompts the user to install DirectPlay, but this requires a certain combination of services to be active such as the Diagnostic Policy Service which are sometimes disabled by the user.
