Wee!!! And I couldn't find a product ID for the new OEM license I purchased.
Built PC myself.
1HDD: Had WinXP on it. Used XP for many years.
Purchased Win 7 Pro upgrade and new HDD.
Formatted HDD, installed WinXP, then used my Win 7 Pro upgrade to install Win 7 Pro. Made new HDD primary boot drive.
Built PC myself.
Salvaged primary HDD (that had Win 7 pro on it) from PC1 and use that as primary HDD for PC2.
Purchased a new Win 7 Pro OEM license (have not used yet)
Now both PC1 and PC2 have 1 HDD. Wife will use PC1, I will use PC2.
I would like to use the OEM license on PC2, because I am thinking that within the next 1-2 years, I will probably reformat the primary OS partition on it. I want to use the OEM license because then I don't have to go through the 1+ hour process of installing WinXP first, then using the upgrade to install Win 7 Pro again. With OEM license, I can just straight up install Win 7 and save myself time and frustration.
Win 7 detected that my hardware had changed (completely new everything except for HDD) and it auto-activated itself successfully. But again note, this is the upgrade license, which I do not want tied to the new PC2.
So I want to:
Switch the license on PC2 from the upgrade license to the new OEM Win 7 pro license that I bought (but have not used!), and then I will reformat the old hard drive on PC1, reinstall WinXP, then use the upgrade CD to install Win 7 pro upgrade license back on PC1 (Where that license was originally).
1) Is my plan sound?
2) Will I encounter problems if I try to install the upgrade back on PC1 (where it was originally, just different HDD) because PC2 recently auto-authorized itself using the upgrade license - even if I first switch the product ID?
3) I opened the OEM packaging and I do not see a Product ID, only a Product Key. I want to avoid reinstalling windows on PC2 and just use the "Change product key" feature and switch it to the OEM license. But I do not see a product ID anywhere on the OEM packaging. What do I do?
