So, being the computing geek I am, what do you think my first move would be when Windows is completely broken beyond repair? Take out the restore DVD and reload from scratch? Nope, in this case it was remove the beading from the inside of the pane, take out broken sealed unit, pop down to the glaziers and order a replacement one, then put new sealed unit in frame and replace beading. Changing the glass in a double-glazed uPVC frame has got to be one of the easier DIY jobs I’ve done so far and surprisingly (to me) cheap.

How and who broke the window?
