Okay, I know that there should only be ONE csrss.exe in the system32 file, right? Well, I did a search of my PC and it came up with a few in winsxs and now one in windows]software distribtion\download... with file names like x86_microsoft-windows-csrss_31bf3856ad364e35_6.0.6001.18000_none_58e3e3d7e415ae4c do i delete these? or are there normal?
