Following on from its previous update, Microsoft has unveiled 27 more changes it plans to make before upgrading Windows 7 from beta to release candidate. Once again, these are small tweaks based on user feedback aimed at improving the desktop experience, and more such adjustments are expected to come as Microsoft rushes to get their next operating system out the door.

This time the company has made some usability tweaks to how the taskbar thumbnail overflow feature works, modified the Control Panel Jump List so that it offers quick access to recently used items, and particularly focused on improving several aspects of the Windows Explorer file manager. Interestingly, Microsoft also decided to trim the shutdown and logoff sounds to gain up to 400 milliseconds because “every little bit counts.” The rest of the changes involve a number of different performance and operating areas, you can check out the full list on the Engineering Windows 7 blog.
