I hope you don’t need this.  I hope that if you do need it, you have another computer where you can download it.  I hope you have it stuck on a thumb drive somewhere.

Or to be safe, download it now.

If your winsock stack gets corrupted, use this program winsockxpfix.exe.  You’ll be glad in that one time out of ten thousand that you really need it.

Oh, but it’s not safe, you say.  Oh, but it’s not supported, you say.

Oh, Microsoft MVPs recommend it, I say.

Seriously, if you do computer support, this is a magic wand and a silver bullet.  Get it before you need it, because once you need it, it’s too late.
