Thanks, JonePeng.
But those programs will all more or less affect the operation of some programs under DOS. The best way is still to start with COMMAND.COM and modify the part in it related to CTRL+C disabling. Expert willsort should be able to do it, so please give it a try, willsort. I think a lot of friends need this, and no matter how you search on Google and other search sites, you just can't find any relevant materials. It's really maddening.
Experts, please help out, I'm begging you.
