http://boinc.berkeley.edu/download.php Came out at the end of July and I missed it. Release notes for version 6.2  New features  Improved Windows security BOINC now offers Protected application execution: in this mode, applications are run under an unprivileged account, so that they cannot access your files. NOTE: Choosing this option will require a reboot after setup has completed the installation. Setup creates several users and groups on the system and you will not be able to properly manage BOINC until after the system has been rebooted.  Windows Vista compatibility BOINC Manager now starts up without any security warnings when you log in. Application graphics now work in all cases.  Support for multiple selection in GUI You can now select multiple items (projects, tasks, etc.) and operate on them as a group.
