What do you mean by cut off? Do you mean that you cannot see the Temporary Internet Files folder within the ..\Microsoft\Windows folder?
If it is because you cannot see the folder, then the reason is because you have not set the folder options to show protected Operating System files/folders. This is a good thing and I suggest that you leave it the way it is. It is to stop people from messing with important files/folders that could have serious adverse affects on your system if handled incorrectly.
If you wish to have a good clear out of temporary files, use a program such as CCleaner.
CCleaner - Optimization and Cleaning - Free Download
Be warned, CCleaner comes with a registry cleaner, it is advised not to use it. So called "cleaning your registry" provides very little, if any, advantages and has a high risk of causing many different problems, best to avoid them.
