Why would you execute a command about which you know

nothing at all? A perfect recipe for a disaster?

 

You can undo the damage with much the same command:

 

cmd /c for %a in (d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z) do subst

%a: /d

Who sent it by email?

 

If you share any of those drive letters over the network (and

potentially, the Internet), you may now be exposing Windows subtree

(with all those lovely malware integration opportunities) via the

shares of other drive letters. I can't see a good reason to do that.

Well, it would; that's what it does.

 

What did you think it would do?

 

I have to say, this post reminds me of an old (pre-Win95) cartoon in

Punch, where there's a husband reading a newspaper ad to the wife:

 

"It says here, I can have my name added to a list of confidence

trick victims for only ten pounds!"
