I have two PCs I would like to upgrade to Windows 7 64bit. Both are currently running 32bit. The desktop is a Dell Inspiron 530 running Windows Vista. The laptop, a HP Compaq nc6400, is running Windows XP. I have run Upgrade Advisor on each.
On the desktop Upgrade Advisor indicates I can upgrade to a 32 bit option but have to do a custom install for the 64bit option.
On the laptop Upgrade Advisor indicates a custom install is needed for both 32 and 64 bit installs.
My first question is - is Upgrade Advisor looking at my hardware and validating it will support a 64 bit install or do I have to do that investigation independently?
Secondly my understanding of a custom install is it wipes out all files and requires complete reinstallation of all software. I am running Microsoft Office 2007 on both PCs and do not have the installation CDs. I purchased the desktop and the laptop was given to me.
What are my options or procedures for upgrading these PCs?
Thanks for your help.
