Windows 7 Professional, Enterprise and Ultimate include the XP Mode. This is a virtual mode. It is powered by Windows Virtual PC for Windows 7, a more advanced version of Microsoft Virtual PC. The XP mode is designed for programs that do not work even in compatibility mode. Communication with the host is much easier compared to Microsoft Virtual PC.
New drives that are connected to the main computer are automatically detected in XP mode and the clipboard can be used by Windows 7 and XP mode simultaneously. Also, USB devices are detected by the virtual machine. This allows older USB hardware for which there are no new drivers to use in the virtual machine.
However, 3D acceleration must be dispensed within the virtual machine. The Windows XP mode is therefore suitable for 3D games or 3D CAD unsuitable. To use the XP mode was up to an update in March 2010 requires a main processor with AMD Virtualization or Intel VT handled by Computer Repairs in Wagga.
Microsoft first allowed owners of certain single-user licenses, alternatively to use not only the direct predecessor of the new-generation operating system, but either the pre-predecessor. This downgrade option was accounted for with the provision of the first service packs for Windows 7.
Windows PowerShell is installed in Windows 7. This feature provides a development environment for command-line scripts. Thus, it offers an alternative to cmd.exe and resembles UNIX shells such as bash.
With Windows 7, DirectX 11 was released as a new version of the DirectX API.

DirectX 9 may be installed for such programs in addition to DirectX 11 handled by Computer Repairs in Wagga.
Some programs and features that were part of the previous version in Windows 7 are no longer available or have been outsourced. Windows 7 needs tend to be somewhat less resource intensive than Windows Vista, yet the officially recommended minimum system requirements are slightly higher. The graphics card requirements depend on the three graphics modes (visual designs) and resolution. There is no further requirement in the aero-modes, however, additional requirements must still be met.
Windows 7 is more usable on netbooks than Vista, if they have at least a 1 GHz processor and 1 GB of memory. However, it is slower than the eight years older Windows XP. To install the operating system a DVD drive or a USB port is required. Windows 7 includes a number of features for easier operation by users.
