Loads a memory-resident program into memory. Use the systemroot\System32\Config.nt file, or the equivalent startup file specified in a program's program information file (PIF), to specify the program to install.


install=[Drive:][Path] FileName [CommandParameters]


[ Drive : ][ Path ] FileName : Specifies the location and name of the memory-resident program you want to run.

CommandParameters : Specifies parameters for the program you specify for FileName.

/? : Displays help at the command prompt.


  • Use install to load a memory-resident program into memory just prior to starting the application that requires the memory-resident program. If a memory-resident program is loaded into memory using the Autoexec.nt file, the memory-resident program will be loaded into memory every time the command prompt is started, wasting memory.

  • Do not use install to load programs that use environment variables or shortcut keys or that require Cmd.exe to be present to handle critical errors.


To load a program into memory in the Config.nt file, type the following:
