When you tipped the water out, did you catch the small packet of silica gel?
You have to have one of those in there, apparently.
Which detergent did you use to clean the registry?
Did the water have any ice cubes in it? You may find that Windows has frozen - but scraping them with a credit card usually helps (it used to do on my car windscreen when I lived in UK).
I presume you now do Guggle searches?
