Hacked!

I was sipping a cup of coffee, switched on my computer, and waited for windows to load. Typed my administrative pw a few times, but I keep getting a msg saying that I typed the wrong password. I am positive that I didn't forget my pw. I've used it for years. I typed a few other pws that I use, still the same thing. Then it sunk in! I was hacked! I was hacked on Valentine's Day! I suppose this is what people call 'tough love.' My unlucky stars must have all lined up.

.

I am not sure what to do in order to get inside windows at the moment. I don't know how to reset my pw. Sure, I can always take my machine to the shop, but I'm not sure I want to do that. I have important stuff saved in my machine. I prolly need to buy a software for pw recovery. I'm not very sure if such thing exist. Anyway, just venting a little.
