The original Microsoft FreeCell package supports 32,000 numbered deals, generated by a 15- bit, pseudorandom-number seed. According to company telemetry FreeCell was the seventh most-used Windows program, ahead of Word and Microsoft Excel.

Microsoft created the Entertainment Packs to encourage non-business use of Windows. FreeCell is not included in the Windows 8 operating system but is available in the Windows Store as the free Microsoft Solitaire Collection, which is also bundled with Windows 10.

Some features have been removed, such as the flashing screen to warn the player of one move remaining. The Windows Vista FreeCell implementation contains basic hints and unlimited move retraction (via the Undo menu choice or command), and the option to restart the game. Prior to Windows Vista, the versions for Windows were limited in their player assistance features, such as retraction of moves. Today, there are FreeCell implementations for nearly every modern operating system as it is one of the few games pre-installed with every copy of Windows.
