When I go into explorer, I see lots of files under Windows TEMP, but I cannot delete them. Why not? What are they there for? There is another TEMP file and I cannot delete any of these files either. I don't understand. I hope you can help me out.
A little knowledge can be very dangerous. If you want to clean your system I suggest you download a program like CCleaner that will safely delete junk files. Just Google "CCleaner" for a download location.
