Since upgrading from version 5 to 6 a few days ago, my Win7-64 VM has had two sudden forced shutdowns, initiated by the Parallels tools: The process prl_tools.exe has initiated the power off of computer ***** on behalf of user NT AUTHORITY\SYSTEM for the following reason: No title for this reason could be found Reason Code: 0x80020000 Shutdown Type: power off Comment: The process prl_tools.exe has initiated the power off of computer ***** on behalf of user NT AUTHORITY\SYSTEM for the following reason: No title for this reason could be found Reason Code: 0x80020000 Shutdown Type: power off Comment: This is build 11994. The tools in the VM are up to date. Can anyone shed light on this? Thanks, Gary Kratkin
