Ok, I have used computers for years and I am very goo with them but there is one thing I need help with. It's where you can set a folder or an item on your desktop\somewhere else and it is invisible. The thing is I don't know how to make it so that it is visible again. (before you start trolling on me and be like zomg you idit don't even know how to use a computer properly you need to take a computer class, I have never used the hidden icon trick before).

The option to view hidden files is within your Folder and Search options, in the view tab.
From there it shouldn't be that far down where you can see this:

Just check Show hidden files and folders, and click okay.

Find the file you no longer want to be hidden and right click it, select properties and deselect the Hidden attribute.
Click okay and you're done.

Thanks a lot for the help! .
