'Installing' my friend's new computer for him involved:
(i) connecting it to his wifi ;
(ii) installing the driver for his printer ;
(iii) copying all of his documents, photos, etc from his old PC to his new one ;
(iv) setting up his email client with his account details and checking that his old mail could still be accessed from his new computer ;
(v) installing his preferred web browser ;
(vi) exporting his profile from the web browser on his old PC to the browser on his new one, so that his bookmarks and personal preferences were maintained ;
(vii) downloading and installing free software (such as OpenOffice) onto his new computer to replace commercial software (such as Microsoft Word) which he's had available to him before but which didn't come pre-installed on the new machine ;
(viii) changing the default settings in OpenOffice to ensure that documents were saved into Microsoft formats ; and countless other things! It took nearly a full working day in total (although that did include a leisurely, and somewhat liquid, lunch!), so I'm surprised that some people here think that there's nothing more to setting up a new computer than simply plugging it in!
However, to actually answer BB58's question: Yes, the guy CAN still visit your home to install your new PC.
