But! In the Windows world Free Apps are not so Free and downloads can be complicated - on purpose to make you download something else.
If you are the impatient type and have got the right download then you install it fast by clicking OK and OK and OK..and thereby accepting add-bars and other "handy" extensions to your browser
It will fill your computer with a load of crap

Now there is a site - Ninite - where you can pick the download and then you will be asked to download a custom installer.
In fact you don't have to install it and can simply run the exe and it will clear your App from crap-ware and also keep track of updates - without crapping your computer!

It is free but you can spend money on a pro version....
Time well spent to keep crap away if you ask me...
