I have brought acer aspire E1-571 ore i3 laptop with windows 8 operating system. For activate windows it ask product key. But there isn't product key in my laptop. So how to find the prdoduct key.
Probably best to use Microsoft's own Produkey finder http://www.nirsoft.net/utils/product_cd_key_viewer.html
Though your Key is encrypted and embedded in your BIOS, and should have been read and activated windows automatically...
It is usually on a sticker on the underneath part of the laptop.
It could possibly be with the documents and manuals that came with the laptop but unlikely.
windows 8 doesn't include product keys on labels anymore. its all encoded in the bios and should be automatically read when using the original install media for that computer (restore disk or media)
