A large issue with all versions of Windows is by default the Operating system is installed to not show your file extension. FolderOptions

So why is this a problem? Well since Virus developers and Script kiddies learned of this they would mask the virus file as a jpeg. So please what ever version of windows you are using please uncheck Hide extensions for known file types.

If you notice in the diagram on the left I would and do the following on every install of any Windows version I install.

-Uncheck Automatically search for network folders and printers

-Check: Do not cache thumbnails

-Bullet: Show hidden files and folders

Click apply and then Apply to all folders. Windows will prompt you to make sure. Click ok.

Now when you download a file or someone sends you a file you know what the true extension of the file.
