If I recall correctly, after the installation is complete, Windows setup asks you if it should perform all the necessary changes to the config.sys and autoexec.bat, or if you prefer to do it yourself. My assumption is that you did not let setup modify those files.
Normally the windows directory, C:\WINDOWS in your case, will be added to the PATH line in the autoexec.bat. I would check it and modify the path manually if it's missing.

Hi, please check autoexec.bat, there's a PATH= line.
Windows directory should be included.

For example:
PATH=C:\WINDOWS;C:\DOS;

The order can be other way round, too.
It depends what's more important; if DOS directory has newer files than Windows, for example.

Good luck! 😀

solved redoing install but instead of doing it from a CD, I did it from the hard disk, and then It was able to ovewrite the autoexec.bat enabling the C:\WIN command

Good that you solved it, but installing from a CD was not the reason win.com's location was not added to the path. Probably this time you just let setup modify autoexec.
