There are a number of files and folders wannacrypt will avoid. Some because it's entirely pointless and others because it might destabilize the system. During scans, it will search the path for the following strings and skip over if present:

• "Content.IE5"
• "Temporary Internet Files"
• " This folder protects against ransomware. Modifying it will reduce protection"
• "\Local Settings\Temp"
• "\AppData\Local\Temp"
• "\Program Files (x86)"
• "\Program Files (x64)"
• "\Program Files"
• "\WINDOWS"
• "\ProgramData"
• "\Intel"
• "$"

The filetypes it looks for to encrypt are:
