If you search the product key through Google I'd bet you get a lot of results for it. smile.gif

The bottom line here is if you need to have Windows 8 again on this Acer computer of yours, you need the installation disk from Acer OR you use the recovery partition of this computer.

Googled it, no results at all.

I've read that some new laptops are coming without the COA, instead it is programmed into the UEFI BIOS. You will probably need to get an OEM Win 8 install disk to reinstall with, and then it should find the key from the BIOS. You will have to make sure you install the correct version of Win 8 though, otherwise the key won't work. (32 bit vs 64 Bit, home premium vs pro etc etc, just make sure you have the exact version it came with)

The two links below, while not directly targeted for your laptop, may have helpful snippets of information. :-)

The Dell Machines (Optiplex 9010) we have here just have a Windows 8 sticker but no Windows 8 product key sticker. They each come with a Windows 8 installation disk that has a Dell logo. You use those disk on this particular Dell computer model they will install and activate, but on older Dell computers (Optiplex 360, which does not have a UEFI BIOS) they'll ask for a PK. You might be on to something here about the UEFI BIOS. thumb.gif

Unless this has changed with windows 8, OEM keys have always worked as many times as you install it on the same machine. But once the motherboard is changed it will no longer work.

Yeah, I think OEMs are using the new BIOS as a way of storing the key, it was a change made cos stickers were being rubbed off from underneath the laptops. Its not something intrinsic to UEFI BIOS's, just that they are using the features of UEFI BIOSs to store the key in the case of OEM installations.

Actually, with this change, in the case of OEM equipment, it does make motherboard swaps easier, as the key will be built into the motherboard. SO swap the board, reactivate, and off you go. smile.gif

Though I'm sure even with key stickers, you can still reactivate, I've did it on a few machines i've had to do board swap repairs. I think its only if you upgrade many parts, IE do a ful MB,CPU,RAM etc that it will refuse a reactivation, as then you basically have a "new" PC.
