I have Windows XP home on compaq presario. I would like to restore this to factory settings. I bought an external hard drive and moved all documents, images etc. Now I am happy to delete all we added but would like to keep the programmes. Don't really know how to and started removing stuff and accidentally removed Microsoft Office....I have various discs for this so I should be able to install when I have 'cleaned up' the pc.
Doing this as it has become VERY slow.
