Might I make a brief 'Tech.' query:
I`m considering reinstalling the Windows Vista on this ever-more creaky laptop; every morning there are corrupt and orphaned files and 'chkdsk' has to work wonders, but I realise that things can`t continue in this state for much longer.
A fellow ER has suggested I try a clean re-installation.
I have successfully managed to backup to USB-DVD drive all things most important (Pics/Docs./Network-settings/Logins and Bookmarks etc.), but having thought about the various likely associated tasks in proceeding; I think that subsequent to a 'clean install' I will surely be asked for the Windows security number-series that used to be readable on a sticker `neath the machine...........however, with these 8 years of handling, it has worn away, almost completely.
I have a bootable Windows Vista Recovery CD (which I created/burned several years ago) and I also have a Windows Vista {upgrade} DVD, which came with the machine when purchased and I have been led to believe the latter DVD may also be used to perform a clean reinstall; although being a generic-use disc, it does not have any serial number stickers.
The laptop`s internal CD/DVD disc-drive failed several years ago, but the external DVD reader/writer I have, will work for booting if I make an appropriate USB boot-source selection from within the BIOS.
Is the missing original Windows Vista serial and authentification number, recoverable via the Windows U.I?.......If not, is there another way to authenticate for re-installation?................Have I missed anything in my progress so far?
