Batch file to delete TEMP files and more

For years I used a simple app named DeleteGU to delete TEMP files off a PCs hard drive from within PE.  I used it  before imaging, or just as a general cleanup utility. Alas, it is not compatible for Windows Vista / 7 / 8 and the author is no where to be found. So I wrote a simple batch file to do it with.  It deletes USERS and SYSTEM temp files, Temporary Internet files and deletes the page file and hibernation file.  I wanted something small and lean and without working through Runscanner.

Here are some issues:

• I can't suppress all error messages despite driving output into NUL
• I can't seem to actually DELETE the $RECYCLE.BIN, I can empty it but not deletes it, this causes a corruption error the first time Windows is started.
• 2 dependencies: ICACLS.EXE to enable deletion of the hiberfil.sys file, else access is denied, and ATTRIB.EXE, both must be in your build.
• I ran into some mysterious HIDDEN or READ ONLY files occasionally, this is why the extra step of using ATTRIB was added
• You must enter the REAL Windows OS drive a the prompt or command line, Wonko came up with a brilliant script to determine the REAL OS drive, but alas, I am too stupid to figure out how to combine it with this script.  Check it out

So guys-n-gals, tear it apart, make it better or use it just the way it is.  If we can get it looking better then I'll wrap it in a Winbuilder script to make it build ready.
