RE: 32-bit to 64-bit upgrade
I really don't care that my Vostro 420 is out of warranty, or that Windows 7 is not downloadable, or that I will have to purchase the 64-bit version at eBay.
My question was if the 64-bit version would run on a desktop that came with the 32-bit version. Can anyone else answer that question, or must I look elsewhere for advice?
P.S.: I installed a solid-state hard drive more than five years ago on the Vostro, and it did NOT significantly "speed up" that system. Also, I have Windows 10 on four other computers here in my office, and I don't need another instance of that OS, thank you very much.
