I'm busy trying to "clean up" my nephew's PC, which he was given by his parents, the original purchasers. I have tried repeatedly to get Vista SP1 to install, without any success, even though I've tried many strategies suggested by technical forums. I therefore wanted to see if reinstalling Vista would allow me to do this. Unfortunately, because it was around 2006 when they bought the machine, they cannot remember the password. I'd like to know if re-installing would allow me to bring Vista right up to date with the SP1 & SP2 (the latter cannot be installed without SP1) and, if so, if there is any way I can achieve this without either the original system password or disks. I have posed the question direct to Acer, but not getting any direct answer. I have already copied all personal files. Would I also lose other installed programs? Incidentally, there is around 80GB of space left on drive C.
Thanks in advance.
