I have Windonws 7 Professional running on several virtual desktops (VMWare View). The virtual desktops go to sleep after a few minutes, and require a password on wakeup. I've read a number of threads that deal with either disabling password on wakeup, or preventing the OS from going to sleep altogether. The problem is that all of those solutions refer to settings options that I don't have. Two examples: If I open the Power Options control panel, there is no 'require a password on wakeup' option in the left-hand frame.If I go into the advanced settings for any of the available power plans, the only option under Sleep is 'Allow wake timers'. There is no 'Sleep after' or 'Hibernate after' option to change. How can I stop these machines from sleeping, or at least stop them from requiring a password on wakeup?
