you are right in Vista OS it doesnt generate a serial,
Microsoft allows large hardware manufacturers (e.g. ASUS, HP, Dell) to ship their products containing a Windows Vista installation that does NOT require any kind of product activation as this might be considered an unnecessary inconvenience for the end-user. Instead these so-called ‘Royalty OEMs’ are granted the right to embed certain license information into their hardware products, which can be validated by Windows Vista to make obtaining further activation information (online or by phone) obsolete. This mechanism is commonly referred to as ‘SLP 2.0′ (’system-locked pre-installation 2.0′) and consists of the following three key elements:
The OEM’s hardware-embedded BIOS ACPI_SLIC information signed by Microsoft
A certificate issued by Microsoft that corresponds to the specific ACPI_SLIC information (The certificate is an XML file found on the OEM’s installation/recovery media, ususally called something like ‘oemname.xrm-ms’)
A special type of product key that corresponds to the installed edition of Windows Vista
This key can usually be obtained from some installation script found on the OEM’s installation/recovery media or directly from a pre-installed OEM system
If all three elements match Windows Vista’s licensing mechansim considers the given installation a valid system-locked pre-activated copy (that does not require any additional product activation procedures)
So the basic concept of the tool at hand is to present any given BIOS ACPI_SLIC information to Windows Vista’s licensing mechanism by means of a device driver. In combination with a matching product key and OEM certificate this allows for rendering any system practically indistinguishable from a legit pre-activated system shipped by the respective OEM
In the other words, by using this tool, you’re bypassing the product activation requirement of Microsoft Windows Vista ...
In XP, 2000 and 98 it does generate a serial..
Ive been facinated with what they do and I've been "trying" to learn how to program in C and a little assembly. well I been trying to make time to learn anyway...
Looks like time is showing that the little man has the edge over the GIANT, lets hope that the david and goliath story doesnt repeat
