simple way: delete everything in %appdata%\bitcoin except for wallet.dat, then restart the client

faster way: use pywallet to manually remove the transaction from your wallet.dat, then run "bitcoin-qt.exe --rescan"

It is pitch black. You are likely to be eaten by a grue.

You shouldn't ever need to do this. The page you linked to is for an Android app called "Bitcoin Wallet" (perhaps a bit confusing but there it is).

What transaction isn't confirming? If you leave it for a while it probably will confirm.

Believe it or not, I've had exactly this situation happen with a transaction that perpetually would not confirm.  I purposefully spent it without a fee, it's been two weeks now.

I'll let you know if resetting the blockchain helps.

For a faster solution without needing pywallet, you could just delete the most recent block database and chainstate files, then start bitcoin-qt with --rescan. It should still work, provided transactions aren't stored in wallet.dat after they've been broadcasted, which I'm not certain about. If they are, you'd have to either use pywallet or restore from a recent backup.
