Please help for "not genuine win 7 after hard drive upgrade

Thank you, I will definitely try it.

As you said, I recalled, it initially came with vista and free upgraded win 7 home CD, 'cause I have no memory ever used vista on this PC, actually, I never used vista in my life. Later, I got a ultimate acer oem key, just run a upgrade that convert the home to ultimate, and I have been running it for nearly three without problem until upgrade to new hard drive recently.

I still kept my old drive, I think I could boot up from it externally, I will run diagnostic tool on the old drive, then post the results here, maybe it could let you to get insight how this odd thing happened.

Thank you so much.

The installation of Windows is Counterfeit - the OEM_SLP key is NOT a valid Upgrade Key.

If the COA sticker is for Windows Home Premium, then that's the only version licensed, unless you purchase an Upgrade license through a retailer, or MS itself - and those licenses ALWAYS show as 'Retail' in the report.

There is no overlap in BIOS/WIn7 release dates - certainly not 3 months.
This machine was shipped with Windows Vista installed, and a Vista SLIC table. It has had a hacker's Activation Exploit installed to circumvent activation/validation requirements, and is therefore by definition non-genuine.

There is a possibility that the machine came with a freebie upgrade to Windows 7 - but such upgrades are ALWAYS OEM System Builder Keys, and again, can only be upgraded using a Retail Key

I could not boot up from my old drive through usb sata, it suddenly stops on windows 7 starting animation, don't know why. I guess, in order to boot up from it, I have to do it as internal HD.

I found the original window 7 upgrade CD with the key, but it is Home version. Could I use this key to try, literally downgrade from ultimate to home, if I do so, what could happen, will some program could not be run properly because of home version. And if somehow it solved the problem, could I upgrade to ultimate version later. Thanks

I'll try that again - :embarrass:

The OEM_SLP Key in use is NOT an upgrade Key, it's only v
You must use the one that came with your Windows 7 disk as the freebie upgrade (which would have come through the post).
The installed OS is counterfeit by definition.

If you can get the old disk working again. try using Magical Jellybean to recover the Windows Key from that - if it's the same one as current then that was also counterfeit.

Thank you. To do fresh installation will be too hassle for me, I had so many programs and personal settings, that is why I did image when I upgrade my hard drive. As I understood, unlike MAC OS, there is no simple way to migrate whole data after OS installation in PC.

I had one question, could I use those so called "boot loader" to trick the system that I am running genuine one. So far, the warning is rather annoying than actually bother me doing anything, just microsoft essential could not be updated. Thanks again

By the way, since there is hidden 1st PQsevice partition, I guess the "boot loader" may not work, am I right.

You will have to do a clean install - for two reasons.
1) it's not possible to do a downgrade install
2) OEM installs are always clean installs, by design.

Sorry, I got it. Just be a little frustrated, I bought the system, but it said I am not running genuine one.
