Win8 activation: can flash BIOS to activate Win8

For users who purchase Windows notebooks and desktops in many retail stores, you should be familiar with the labels attached to the back, bottom, or manual of the machine. The product key for Windows will be printed on this label. The existence of such a tag is actually a bit of a problem. For example, anyone can easily get this key from this relatively clear location and legally activate the Windows system on other machines. In addition, the computer has been used for a long time, and the words on the label will wear out. If the key is not clear or the manual is lost, it will be more troublesome to reinstall the system. Windows 8 has designed a new key storage solution for this: it is placed on the motherboard BIOS.

For Windows 8 users, Microsoft changed the process of requiring users to enter the Windows system and painstakingly entering the key, embedding the key information into the BIOS. Remove the label that was originally posted on the PC, to prevent the malicious elements from maliciously obtaining the user's key, and secondly, there is no need to worry about accidentally tearing up or the label being illegible. Thirdly, the user is also facing the keyboard. The trouble of typing alphanumeric.
For machines pre-installed with Windows 8, if the user needs to reinstall the system, the installer will automatically obtain the product key from the motherboard BIOS, without the user having to manually enter it. This means that the key label will no longer appear on future Windows 8 devices. However, this mechanism seems to be facing some problems.
For example, if a user purchases a laptop with a pre-installed Windows 8 standard, then the user wants to upgrade to Windows 8 Pro, and they will run into problems. According to technology blog Ghacks, Windows will check the key information on the motherboard BIOS during the installation process to activate the current version of Windows instead of the Professional version. And if the user intends to assemble a machine by himself, there is no Windows 8 product key information on the motherboard, and how to purchase a Windows 8 retail version.
