There are many ways to determine the system type. The simplest is to use the variable %OS%, which has a value of Windows_NT under NT series, otherwise it is empty.

Thanks to the team for your instruction!!! What about in the WIN95/98 system? I wonder if there is a %OS% system variable????

Under Win9x, there is usually no %OS% system variable, while under WinNT series, its value is all Windows_NT, so it can be simply judged.

```
if NOT {%OS%} == {} goto winnt
:win98
::Code for win98
goto ENDOSDECTED
:winnt
::Code for winnt
:ENDOSDECTED
```
