No Smoke without Micro$oft.

A guy rings tech support to report that his computer is faulty.

Tech:
What’s the problem?
User:
There is smoke coming out of the power supply.

Tech:
You’ll need a new power supply.
User:
No, I don’t! I just need to change the start-up files.

Tech:
Sir, the power supply is faulty. You’ll need to replace it.
User:
No way! Someone told me that I just needed to change the start-up files and it will fix the problem! All I need is for you to tell me the command. Ten minutes later, the User is still adamant that they are right. The tech is frustrated and fed up.

Tech:
Sorry, Sir. We don’t normally tell our customers this, but there is an undocumented DOS command that will fix the problem.
User:
I knew it!

Tech:
Just add the line LOAD NOSMOKE.COM at the end of the CONFIG.SYS. Let me know how it goes. Ten minutes later.
User:
It didn’t work. The power supply is still smoking.

Tech:
Well, what version of DOS are you using?
User:
MS-DOS 6.22.

Tech:
That’s your problem there. That version of DOS didn’t come with NOSMOKE. Contact Microsoft and ask them for a patch that will give you the file. Let me know how it goes. One hour later.
User:
I need a new power supply.

Tech:
How did you come to that conclusion?
User:
Well, I rang Microsoft and told him about what you said, and he started asking questions about the make of power supply.

Tech:
Then what did he say?
User:
He told me that my power supply isn’t compatible with NOSMOKE.
