ASM Community

I am ready to start working on the all purpose one click shutdown of any Win OS.

Do you have time to help me with it if I post what I last had. (And I lost a bunch when my HD cratered)

If there was an easier to way to search here for my past code postings, I'd download what I could.

Thanks, I found this. I currently use it but I recall it didn't work on a Win2K machine.
Like to fix that.
