Question: Can this be used to install Windows 7 Pro via a Virtual Machine setup eg VirtualBox or VMWare?
Document: Early on the install asked for RAID drivers. I had found them on Highpoint's website for Windows 7 and loaded them onto a USB thumb drive. I browsed to the USB drive and the Windows 7 Install picked up the drivers and went right on an installed the OS successfully.This old XP business machine is seeing new life with its shiny new Windows 7 OS. It seems to run faster over all than it used to. It definitely does not run slower. I am very pleased with how well this install worked. And, we can take advantage of the large RAID secured storage space on our home network as well as having an upgraded Windows 7 computer.
Windows 7 Pro used as part of rebuilding old XP Pro system. Wish the new 8.1 was more like Windows 7...
Don't trust third-party software vendors on Amazon!--------------------------------------------------These are legitimate - sealed - copies of Windows 7 Professional(which can be used to activate Windows 7 Pro x64, FYI). I suspect the people that are experiencing issues may be having a hard time reading the even tinier product keys supplied on the slim copies.
In order to change from Win-xp to Win-7 there are series of steps required, it took me the better part of 5 hours. Before any thing, [1] Find out what other people did, some of the win-xp sw apps MAY NOT work with win-7. [2] Copy all the personal files created on the machine by all the different programs [4] The product code to activate is in 1/64 high characters on the &#34;genuine windows sticky&#34;  [5] Follow the direction from the win-7 upgrade [6] Make sure to install the new drivers for the machine.
I was very pleased to be able to purchase and install Windows 7 on a video editing workstation used professionally. Installation was clean and easy.
I am not rating Windows 7 - Windows 7 is what it is. I am rating my experience with installing this System Builder OEM DVD.I installed this on an older HP XP business machine (9 years old) that I had put a RAID-5 (3 drives redundant configuration) into and also has a video card upgrade (nothing really fancy). I was concerned that I could even install this at all. The Windows 7 Upgrade Advisor said it would work, but I was concerned about the Highpoint RAID Card working (when I originally installed the RAID with the XP OS, I had to temporarily use a 3.5 inch floppy disk - which has since died - to install drivers for the Highpoint RAID card).Well, this install of Windows 7 Professional went without a hitch.
I ordered and received Windows 7 Pro in two days . It was great. But when I put the disc in my drive to install the program nothing happened and that is because the disc I received was blank, empty, nada. So, I ended up returning Windows 7 Pro and purchasing Windows 8 from Microsoft. Also, Microsoft sent me a ram memory stick to upgrade my computer's memory so they could install Windows 8 for me. I put the memory stick in and my computer went out. My computer would have been too expensive to fix because it was kind of old, so I bought another one that has Windows 8 already installed.
The product description told me (1) I could only install it on one 1 machine. That was ok. I'm ok with the license dying when the system dies. (2) It has to be a clean build. That's ok too. My systems got XP on it now. Win 7 NEVER upgrades from anything but Vista.So I was all set right? Not quite. This product comes in a sealed envelope  (you open it you bought it). The outside says you need OEM builder tools to install it even once on 1 machine.You go to the website to get the tools.
I don't know yet. I won't install Win 7 Pro until after the last Microsoft update for XP on Apr. 8th.
I gave this a five star because I already have been using Windows 7 on my other machines and I have had no problems with it. I bought 7 for my home machine simply because XP was no longer going to be supported by Microsoft.
Answer: According to this article, you don't need a copy of Windows to run a VirtualBox copy of Windows (http://pclosmag.com/html/issues/201309/page15.html)...good luck!
