Upgrade windows 7 32 bit to windows 7 64 bit

Hi Everyone

We just bought 50 computers from hp that came with windows 7 pro 32 bit. We get a free upgrade to windows 7 pro 64 bit which i have to do in the office. I've never installed windows 7 before. Can someone give me the steps to do this? Do i have to wipe the whole computer or do i just put in the cd and it does an auto upgrade?

Also if anyone knows do i need 50 different upgrade cd? I got one from hp. I have talked to 2 different people there 1 said yes 1 said no. I will call back again to make sure but maybe someone knows here

Last but not least. In the future when we have a hard drive go bad and i have to rebuild the pc can i get a volume license from MS so i don't have to track down the paticular cd for that specific tower? These are OEM cd's from HP.

Thanks for the help.

You will have to do a clean install, you can;t upgrade x86 to x64.

The same DVD should work for each machine, you will just need the license from the tower for each machine as you install.

Yes, you can buy a volume license from MS.

For questions 2 and 3, you might also look at Ghost or Nlite to either ghost the PCs or slipstream the install disk and save some time.

You cannot do an "in-place" upgrade from 32-bit to 64-bit, so you will need to wipe-and-load.  Just boot to the Windows 7 64-bit DVD, and select Install Now, then when it shows you the disk and existing partitions, click Options to delete any existing partitions, then install on the Unpartitioned Space (this will all make sense as you go through the steps).  This will format the drives anew and put Windows 7x64 on your PC.

You do not need a separate DVD for each machine.  If you have a Volume License agreement with Microsoft, you can use that DVD, BUT you must activate using your VL product key ... you cannot activate using the sticker on your PC.

If you get a Volume License from MS, then you get re-imaging rights - which means you can build a system that includes all the software you want on it, all the updates, etc., and then image it (I don't recommend Ghost or any product you have to Pay for - MS offers Windows Deployment Services (WDS) and the Microsoft Deployment Toolkit (MDT) which are either free (MDT) or included in Windows as a role (WDS).  Once imaged, you can then deploy it to all the machines you have, provided they came with an equivalent license (for example, buy A volume License for Pro and any OEM machine that came with Pro can have that volume license applied, using the volume license key.

Ok so i have to do a fresh install. I'm going to assume its the same steps as a fresh install of Xp. walk thru the steps delete the partions and go from there.

So if i have 1 upgrade cd from HP and i have to wipe 51 computers i will have to look at the cd code on each computer and enter that in correct? I don't need to worry about having 1 upgrade cd?

With MS do i get 1 VL for all 51 computers. Not sure how that works with them. We own the windows 7 license i just want to ghost ( which we have all ready ) a master hard drive and install that on the other 50 computers. I have never done a VL with ms before so not sure the steps.

I believe the minimum buy-in on a volume license is 5.  But once you have it, you have the media necessary to build the image.

WDS can multicast the image to all 51 machines at the same time and you could have them installed in about an hour - all of them.

Correct ... IF you are asked for your product key at all.  Generally with OEM's, the disks don't ask for the product key, as they use a generic and self/auto-activating key embedded in the disk.  The sticker's key won't match what was used to activate, but it is your legal license to use the OS indicated on the sticker.

With VL, you get a single key that can be used on all your machines.  Keep in mind that you technically aren't allowed to clone/image OEM installations for mass deployment - you would need to use your VL media if using your VL keys.  You should also get in the habit of deploying sysprepped images, as sysprep will remove any information specific to a computer, like the SID that is assigned by Windows to a computer when installed.

Using WDS, as leew has described, is designed to do just what you have planned.

This is a little beyond what i know. I understand about the VL single key. That's what we have with our xp. Not sure abou tthe VL media. What would you suggest I do? Keep in mind i'm pretty new to all this.

When you get your VL key, you will then have access to the VL media (DVD ISO for Windows 7 Enterprise edition) that you can download from Microsoft's VL website, burn to DVD, and use to install Windows 7.

To learn more about sysprepping and Windows deployment options for Windows 7, you might watch a few of these free videos on the subject:

Sorry for the big delay. I have found out that you can buy a VL and just wipe and build up the computers. It doesnt matter if its OEM or HPP. The reason why is you have to wipe the computer so you wipe the OEM off and put MS full version. Here is an artical MS sent me on it.  Reimaging-1-.docx
