Whenever, I cannot find something from the search tool, I often turn to
sdtripper2's index, an alphabetical catalogue of thread subjects, a kind of 'Encyclopaedia Teardropicus'. There are quite a few listings under 'windows'.
If that didn't turn up anything useful, I would then craft a new thread asking the question in the thread title, and in the thread body give a full description of your question.
The generous T&TTT community has never failed to help at least in some way with these methods.
Searching for "Installing Windows" is likely to return as many results containing "Microsoft" as "Plexiglass". While your search is perfectly logical to us humans, the forum search engine struggles with natural language searches.
The secret of making search work for you is;
1. to understand the search engines result scoring system and its search language syntax.
2. anticipate as best you can what text other user's posts might contain, by understanding the user community.
3. formulate a search string that contains only the key text you want to search upon and phrases to exclude junk results.
So a better search string might have been "Installing AND Windows NOT Microsoft OR Install AND Windows NOT Microsoft". Note the use of search syntax (IN CAPITALS) and also the conjugation of the verb 'install'.
As a side note to Ashley, I like the look of that boat in your avatar, got anymore pics? :)
