Microsoft's Windows 8 operating system includes many features designed to help protect you from malicious software. Unfortunately, some of these features may also prevent you from completing tasks you wish to complete. Windows automatically prevents the installation of software without a valid digital signature, which can make it impossible to install your own programs or open-source/alpha versions of software that haven't been signed. You can control this setting from your Windows "Internet Options" screen.
