As usual, when Microsoft has a new operating system or productivity suite on the assembly line, the public domain has a front seat show. Microsoft Office 2010 Build 4417 has reportedly hit the Web with some minor tweaks and improved stability.
According to Neowin, the most noteworthy change to Build 4417 is that Redmond has fine-tuned and polished the Back-Stage view feature. The latest leak packs a new upload center to store and share documents online, a new activation system, and updated icons. Users are reporting that the uninstall issues of a previously leaked Mondo build have been corrected, and the current version can be uninstalled.
Microsoft Office 2010 first leaked to torrent sites back in May, and Microsoft pushed out a technical preview on July 13. I have no doubt there will be many more unofficial builds to come. If you're going to partake in that scene, be careful of shady sources -- it's not uncommon for these leaks to be laced with malware.
