Windows 7: If I have to rebuild a Win7 installation ...

If I have to rebuild a Win7 installation ...

I have 3 PCs running Windows 7 Pro x64. Two of them came with that level of Windows, and I have the installation dvd. The 3rd PC is an old one that came with Home Premium. I did an Anytime Upgrade to get to Pro. I have the both the original product key and the upgrade key. I may have the Home Premium installation dvd, but definitely no Pro dvd for that PC.

I'm about to try a completed system restore with Acronis True Image on that old PC. I've heard of other people being unsuccessful doing this and having to reinstall Windows. If I have to do that, can I use the installation dvd from one of the other PCs? If so, will it set the wrong activation code and cause problems?

Actually the Windows installation disc contains the data for every Windows edition, and a file controls which one is finally installed. You can use eicfg remover to modify your existing dvd into a "universal" one. When used, during installation it will ask which edition you want to install, just make sure you chose the one matching the serial for that computer.

I don't feel comfortable modifying the installation disc, even if the process is fool-proof.

You don't modify the installation disc. You make an ISO from it them modify that then either burn a new DVD or create a flash drive to install from.

The original is unchanged.
