Quite a long time ago a windows update caused computers to save 'personal settings' and log out automatically immediately upon log in. At the time my PC only had one User account and the problem was easily solved by a simple restore, removal of password followed by a new Windows Update that solved the problem. Have just 'inherited' a Fujitsu laptop, running XP, that has this problem update but, unfortunately, has 2 user accounts and, apparently the owner tried logging in on both accounts so the Restore to last successful . . doesn't solve the problem. As the info on the laptop is of no interest to me I would have been happy to format the hard drive (probably would have anyway if there had been NO problem with logging on so as to set it up as I like) but the inbuilt cd/dvd does not work. Have tried plugging in an external cd drive but can't get it to work as needs to be installed with windows. Have an external A Drive so could, presumably, start up in DOS but don't know how to delete the user accounts/passwords. Can any one help? Please!
