I just recently cleaned installed Windows 7 Professional x86 on my Dell Latitude E5400 which previously had Windows XP Professional SP3 on it (OEM, factory installed, was a downgrade option). The laptop however had a Windows 7 Pro OA COA sticker on it so I downloaded a clean Windows 7 Professional x86 iso, made a bootable usb drive for it, and installed the OS; installed/updated all drivers then activated the OS with the key I had (didn't even have to do phone activation). I wish to now switch to x64 as I found out that my laptop is able to be upgraded to 8 GB of ram and x86 only allows 4 GB. My question is, if I clean install x64 replacing x86 will my key still work? Will I run into any activation probelms? I have all my data on an external hard so whatever happens to my stuff on the C drive is cool, I can easily get back.
The ram used by the laptop is a little old (DDRII SDRAM 800 MHz) so is it even worth it to switch to x86 so I can upgrade the ram from 4 GB (currently) to 8GB in the future? I don't really game on PCs, the most extensive gaming I do is MapleStory and I will be getting Minecraft and maybe Torchlight 2 soon. I will be also using Sony Vegas 8 or higher and Photoshop CS3 or higher.
Finally I have Microsoft Office Small Business 2007 which came with the laptop. When I installed Win 7 I did have to reinstall from Office using backup media and then activate over the phone. If I switch to x64 will I be able to use the same key again or will I run to activation problems?
Thanks In Advance!
