# Windows Installation > [HTML Version](windowsinstallation.htm) For purposes of A-Shell installation there are basically three types of Windows environments: • Single users • Local area networks (LANs) of modest size. • Other networks: this broad category includes large LANs, WANs, networks with remote users, networks where multi-user access and/or network traffic are significant concerns, and every other network situation that is other than the two simple environments mentioned above. See [Windows Performance](windowsperformance.htm.md) for more information. **Single User Installation** A-Shell/Windows is normally downloaded from the MicroSabio web site and installed on a PC like any other Windows program. To install, follow the normal Windows software installation procedure—that is, download the appropriate Windows installation program from the [MicroSabio downloads page](http://microsabio.com/downloads/) and then run program, following the prompts and answering the questions. The installation procedure will optionally create a shortcut for [Launching A-Shell](a-shellexecutables.htm.md), and you're off and running. The final step is to run A-Shell, go to _Help...Check for Updates_, and install the latest version of the software. **Subtopics** - [Windows Network Installation](windowsnetworkinstallation.htm.md) - [Files and Registration](filesandregistration.htm.md) - [Installation Problems](installationproblems.htm.md) - [Machine Names](machinenames.htm.md) - [Drive Mapping](drivemapping.htm.md) - [Windows Printers](windowsprinters.htm.md) - [Windows Performance](windowsperformance.htm.md)
