So, you think you know Windows?

If you’re like me, you’ve been using Windows since it was 3.1. You were amazed at the difference between 3.1 and 95, 98 was your average upgrade, you never really understood Me, and XP has been a pretty great ride.

If I am correct, and you are like that, then you’re probably really looking forward to the final release of Vista aren’t you? Although, you’re guess is as good as mine as to when that day will actually occur.

So, with all that knowledge of the variety of reincarnations of the operating system, why don’t you share that one great nugget of joy with the rest of the world and win yourself a copy of the Windows Vista Beta DVD! Yep, that’s the one, the one no longer available to download.

That’s right, share your tip with Lifehacker and you just might win your own shrink-wrapped copy!

So here’s the deal: you post your most useful Windows tip in the comments. We’ll pick a handful of the best ones, and tomorrow readers will vote which is most deserving of the prize. Dazzle us with your Windows expertise, make us swoon in awe at your mighty knowledge of ’softie dialogs and wizards. Your tip should be something clever and handy, like getting rid of the Windows Update nag, renaming a batch of files in Explorer or getting rid of Thumbs.db, but it won’t be considered if it was published here on Lifehacker already.

And even if you’re not interested in playing along, there’s already a great collection of tips in the comments already available, even the humor relief tips of “Install Linux”. Obviously copying something already there would be a little looney, so be sure and read what’s there before you submit your own tip.
