Vista volume license activation cracked already

Senior Reporter, Computerworld PT Windows Vista can be run for at least a year without being activated, a serious end run around one of Microsoft Corp. Livingston, who publishes the Windows Secrets newsletter , said that a single change to Vista’s registry lets users put off the operating system’s product activation requirement an additional eight times beyond the three disclosed last month. With more research, said Livingston, it may even be possible to find a way to postpone activation indefinitely.

What is Windows Hello? Nor is it speculative; Livingston demonstrated the procedure live via a Web conference session today and claimed “we have run this dozens of times.

Combined with Vista’s initial day grace period, that meant users could run Vista for as long as days before they had to activate the OS. Take this online course and learn how to install and configure Windows 10 with the options you need.

Microsoft documented the key on its support site in a description of what it calls “SkipRearm”. In it, Microsoft explains that “rearming a computer restores the Windows system to the original licensing state. All licensing and registry data related to activation is either removed or reset. Any grace period timers are reset as well. In tests with several editions of Vista purchased at different times, Livingston found that copies of Vista Ultimate and Vista Home Premium obtained at the end of January would accept the SkipRearm change only eight times.

Together with the three postponements made possible with slmgr -rearm and the opening day grace period, that would give users nearly a year days of activation-free use. It seems that Microsoft is sympathetic to enterprises’ difficulty in rolling out Vista within the activation deadlines. However, he indicated that the feature could be blocked if Microsoft desired. Microsoft has systems in place to detect and block piracy. Maybe they will want to change this.

But that would only call more attention to activation and perhaps reveal the mechanism Vista is using to count SkipRearm. If someone was to find the count location, however, and manage to change that as well as the SkipRearm registry key, users might be able to postpone activation forever, said Livingston.

Activation was toughened up for Vista, however. After the grace period, nonactivated PCs running Vista drop into what Microsoft calls “reduced functionality” mode. In reduced mode, users can only browse the Web with Internet Explorer, and then only for an hour before being forced to again log on.

Livingston’s work-around, however, may do away with activation altogether. Naturally, Microsoft’s Lazar sees it differently.

Windows XP Professional was initially easy to pirate because the volume license version had no activation built in and leaked almost immediately after its release. The volume license version of Vista does include a copy protection system that requires users to register their license keys with Microsoft and report their usage every month, but ComputerWorld says hackers have already put together software that bypasses this system. To simplify the task of activating many copies of Vista, Microsoft offers corporate users special tools, among them Key Management Service KMS , which allows a company to run a Microsoft-supplied authorization server on its own network and activate Vista without contacting Microsoft for each copy. The software, Microsoft. Server-MelindaGates, lets users spoof that KMS process, allowing them to activate copies of the enterprise editions of Vista, its creators say. The hacked download can be found on various file-sharing sites. The hack might be a little too complex to let just anyone pirate Vista, but it could allow businesses and power users to get around paying for the software.
