I received a used Acer laptop that has a blank HDD so I borrowed a
30 day Dell-packaged Win XP CD to install it which allows it to run Win
XP for 30 days : i've painstakingly got the help of someone in EE to
build in all the NIC, CDROM, WiFi, 3G modem, USB & miscellaneous
other drivers. After searching for a couple of months, I found my
original Win XP licence key for a very old laptop (that's now not
working anymore & retired).
I wanted to use this personal licence which I've found to register into
the Acer laptop but it won't accept, saying it's invalid key. I suspect
the 30-days Dell Win XP CD is for bulk licencing & can only accept
bulk licence but not my personal Win XP's licence that comes with
my old broken laptop.
Is there anyway I can reinstall using my personal Win XP CD but I
wish to retain all the drivers & applications that I've painstakingly
installed : I did not document down how I installed/configured all
those drivers/apps so it's not an option for me to reload drivers/apps.
I do have an Acronis boot CD which could backup the Acer laptop
first if you need me to backup the Acer laptop first before reinstalling
Win XP though
