Software giant battles activation of unauthorized copies of its new Vista OS.
Microsoft today released an update to Windows Vista that will shut down unauthorized versions of the OS that allow users to skip the product's activation system.
The move comes as pirated copies of Vista are already making the rounds, mere weeks after the product was released to business customers.
The update, which Microsoft has dubbed "frankenbuild," detects tampering of Windows Vista code that would allow users of the OS to work around the product's built-in activation system, which requires users to validate their copy of Vista with a product activation key to use the full version of the product after 30 days.
How It Works
Frankenbuild mixes files from various test and final versions of the software. It will require only systems in which it detects specific tampering to go through a validation check for authenticity, according to a posting on the Windows Genuine Advantage blog.
If a version of Vista that has used a workaround to avoid product activation is detected, a user of that software will have 30 days before the OS goes into a reduced functionality mode, Microsoft said. In this mode, all users can do is access their existing files and surf the Web for an hour before having to log back on to the software.
