How to Delete a Product Key Activation in Windows Vista
In every installation of Microsoft Windows, a product key is entered for the operating system to activate. For small to large companies, a network administrator may need to change the Windows product key. To change the key, the administrator can use a small application available from the DOS command prompt called Windows Software Licensing Management Tool (slmgr). The slmgr command has several options, and one of them is "upk." This option removes the product code from the Windows machine.
