The COMPATIBILITY TAB in Windows 2000

This tip was one I had originally posted in the X3dfX forums and has been archived on NuAngel.net for posterity:


Just like the one in Windows XP, you can now enable it for Windows 2000 (SP 2, 3, or 4).

  1. 1. Log on as Administrator.
  2. 2. Click Start, and then click Run.
  3. 3. In the Open box, type the following command, and then click OK, where %SystemRoot% is the drive and folder in which Windows is installed:
    regsvr32 %systemroot%\apppatch\slayerui.dll
    -( i.e. regsvr32 C:\winnt\apppatch\slayerui.dll )


Now you can re-enable Windows NT, 95, and 98 layer compatibility modes to get your older Windows (perhaps even DOS!) games & applications to work again!
