People I was looking for a CPU internal cache slow down utility and I found this software called "CPUspd."

Which I found through here: CpuSpd - A Hardware Based CPU Speed Control Utility for DOS/Win9X Retro Gaming

And I have some questions about this slowdown software.

Does this work on Windows 3.1?

You should download, run and tell us 😀

And does this have the ability to automatically disable the CPU L1 Cache when is DOS session and re-enabling the CPU internal Cache when exiting DOS session on Windows? I would like know please.

CpuSpd is not a TSR so the answer is no. BTW I do not think you can find any utility with such a feature.
But you can create batch files that start CpuSpd before your speed sensitive DOS programs run and also after they quit.

How how do I make those batch files?

With a text editor? Make a text file and rename it such a way that you can recognize it and change its .txt extension to bat ( e.g. myprg1.bat.)
Then paste this (replacing your path and name of your cpuspd and game exe file):

1@echo off
2
3rem disabling cache
4c:\cpuspd\cpuspd.exe cd
5
6rem running program
7c:
8cd c:\myprg1
9myprg1.exe
10
11rem re-enabling cache
12c:\cpuspd\cpuspd.exe ce
13  

Then save the bat file and run it instead of running directly your c:\myprg1\myprg1.exe file.

I'll give that a try.

Well I tried with Mad dog mcree but it gave me a system integrity error in couple of seconds.

UPDATE: Some how I had to remove my ctmouse line on the autoexec.bat file which is like two lines before "C:/Windows/win." And then I had to my ctmouse location line on the .bat file I created.
