Can I fool an application into thinking that Windows 2000 is Windows 95/98/NT4?

The Application Compatibility Toolkit (Service Pack 2 or higher) has the ability to make a program think it is running under Windows 95/98 or NT 4.0.

To enable the toolkit:
Click on start menu, run, and enter "regsvr32 %systemroot%\apppatch\slayerui.dll" and click on OK



You should see this message if the registration is successfully



To select the OS:
Right click on a shortcut of the program, and click properties, the compatibility tab come up. There are three options:

1) Windows 95 Compatibility Layer,
2) Windows 98 Compatibility Layer, and
3) Windows NT4 SP5 Compatibility Layer
