As one of my friends often say - it is better to know what you don't need than to need what you don't know.
In the video above, I have shown an invaluable trick that teaches you a Microsoft Windows skill you will nearly hate yourself for when you need it and you can't seem to have a grasp on it.

It is simple (but consequentially great) - how to rename a file extension. Now you may say - that is pretty easy, just select the file and press F2. But I bet you, you'll grow older than Methuselah if you think that will work for all (in fact, most) files.

Ok, lets put this to a try! Open Notepad, type some considerable gibberish and save the file as gibber. Now try renaming the file as gibber.doc

Oh no! I just lost, or did I? If you double clicked  on the gibber.doc and Notepad came up, you only changed the file from gibber.txt to gibber.doc.txt
Right click on the file and select properties to see the hidden (non-changing) .txt file extension. And that is what I want you to change to .doc, such that whenever you open the gibber.doc file, Microsoft Word will come up.

If you are able to do that, thumbs up! Otherwise, go watch the video above.

Damn it! That download was at 98% and now I have to start all over, why did you close the laptop lid!!
What the F! Installing updates 1 of 98...!!

I can reel off more, but I don't wanna use more swear words. Sticking with the default Microsoft Windows settings can give you some easily avoidable headaches. And in the video above, I have taken pain to explain a couple of settings change I recommend you make.

However, you can ignore some you prefer at the default settings, like the Updates setting and Lock.
