"update folders" automatically created in my local drive

For the last few year or so I've been noticing a lot of folders being created

on my hard disk automatically by the system. The folders have a very long

name such as

"17c362e648ec4aa3e30187024666a5c3" and under that folder there is another

folder called "update". Inside "update folder", there is a file called

"update". The update file looks like an executable file. The file description

says things like:

"Windows Service Pack Setup

Microsoft Corporation

File Version: 6.2.29.0

Size: 699 KB"

Some I can delete, some I can't. I want them all gone... or autosaved to

another location in the future.

PLEASE HELP !!!!!!!!!
