Well...I would examine the contents of any folder...before I ever thought about deleting anything in it.
One utility that will enable you to accurately see the size of that folder, WinDirStat
My Windows folder is currently about 4GB and I have all updates and SP3 installed...I haven't deleted anything from this folder ever.
System manufacturer and model? What steps did you take to do this "repair install"?
