LicenseCrawler is a portable and free tool for retrieving serial numbers and product keys from your computer. A simple scan with LicenseCrawler ensures you’ll never be left trying to reinstall software without the proper key.

LicenseCrawler doesn’t do anything you couldn’t do yourself, it just does it much faster and without you actually having to open up your registry editor. The application scans over your Windows registry file, without altering it, and looks for instances of serial numbers, license keys, and other identifying bits of information.

It found a number of licenses on our test system, but it if the application in question doesn’t store its product key in the registry—instead in the program or application data folder—LicenseCrawler will miss it.

According to a report from My Digital Life, Windows 7 Ultimate has already been cracked with the aid of a leaked OEM DVD ISO from Lenovo. The crack provides permanent instant offline activation and passes WGA with flying colors. The leaked ISO was posted and snagged off a Chinese forum, which allowed hackers to retrieve the OEM-SLP and certificate for Windows 7 Ultimate.

Redmond has updated the system-Locked Pre-installation (SLP) to version 2.1, which supports Windows 7 and Windows Server 2008 R2 – and provides backward-compatibility for Vista and Server 2008. The SLP procedure is used to pre-activate Windows for mass distribution by OEMs. Its latest version requires the BIOS SLIC table be updated, as it contains a new Windows marker. The trick is to mod a system’s BIOS to include SLIC 2.1 – which can be done via hard (physical) or soft (emulation) mods.

The original post gets more in-depth, and contains much more information. Naturally, the crack can already be found on various torrent sites. I’m not about to preach right from wrong here, as you won’t listen anyway. That said, if you’re going to download Windows 7 from an unofficial source, at least verify your copy.

Microsoft has just released a new version of Windows Live Movie Maker which is a free video editing software available for both Windows Vista and Windows 7.

Windows Live Movie Maker now includes several new and impressive transitions and visual effects that are easily accessible from the new Office 2007 like ribbon toolbar. You can even pin these to the title bar of the program for quick access.

Microsoft discontinued Photostory with Windows Vista but the same Ken Burns effect can now be replicated in Movie Maker using the new Pan & Zoom effects (see screenshot below).

Movie Maker can render videos in full High Definition (1080p) format and you also have the option to upload movies directly to YouTube just like in Google’s Picasa software.

The only disappointing part is that Live Movie Maker won’t probably work with your Windows XP system.
