Vista Solution without Vista Disc

Appreciate some help with this one.  My customer has pc running Vista Home Premium.  When it boots, the login screen appears, he enters his password, the welcome screen appears, and then the screen goes blank - just a blank white screen.  Ctl-alt-del brings up task manager, and from there you can get to the run box and launch apps.  All his data is intact, but is inaccessible from the desktop.  Safe-mode gives a blank desktop (black) with "safe-mode" in four corners.


Solution:There was an XP Repair option available on the WinXP installation CD to reinstall XP over itself, which would in most cases not disturb your data or installed programs.  Vista has an option like this also, described here:

The before problem was solved with link, which details a method using a windows vista disc. I have the exact same problem; however, my laptop came with vista already on it and don't have a disc. How can I get the download (the product code for vista is on the bottom of my computer).
