How to run Vista legally without activation ... for at least a year

Brian Livingston has a new trick:Microsoft has built into Vista a function that allows anyone to extend the operating system's activation deadline not just three times, but many times. The same one-line command that postpones Vista's activation deadline to 120 days can be used an indefinite number of times by first changing a Registry key from 0 to 1.This isn't a hacker exploit. It doesn't require any tools or utilities whatsoever. Microsoft even documented the Registry key, although obtusely, on its Technet site.But dishonest PC sellers could use the procedure to install thousands of copies of Vista and sell them to unsuspecting consumers or businesses as legitimately activated copies. This would certainly violate the Vista EULA, but consumers might not realize this until the PCs they bought started demanding activation — and failing — months or years later.The following describes the Registry key that's involved.Step 1. While running a copy of Windows Vista that hasn't yet been activated, click the Start button, type regedit into the Search box, then press Enter to launch the Registry Editor.Step 2. Explore down to the following Registry key:HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ SLStep 3. Right-click the Registry key named SkipRearm and click Edit. The default is a Dword (a double word or 4 bytes) with a hex value of 00000000. Change this value to any positive integer, such as 00000001, save the change, and close the Registry Editor.Step 4. Start a command prompt with administrative rights. The fastest way to do this is to click the Start button, enter cmd in the Search box, then press Ctrl+Shift+Enter. If you're asked for a network username and password, provide the ones that log you into your domain. You may be asked to approve a User Account Control prompt and to provide an administrator password.Step 5. Type one of the following two commands and press Enter:slmgr -rearmorrundll32 slc.dll,SLReArmWindowsEither command uses Vista's built-in Software Licensing Manager (SLMGR) to push the activation deadline out to 30 days after the command is run. Changing SkipRearm from 0 to 1 allows SLMGR to do this an indefinite number of times. Running either command initializes the value of SkipRearm back to 0.Step 6. Reboot the PC to make the postponement take effect. (After you log in, if you like, you can open a command prompt and run the command slmgr -xpr to see Vista's new expiration date and time. I explained the slmgr command and its parameters in my Feb. 15 article.)Step 7. To extend the activation deadline of Vista indefinitely, repeat steps 1 through 6 as necessaryRead ful, story and other tricks at source
