Has Windows Vista been driving you nuts every time you unlock the desktop on a multi-monitor system? It has been for me so I did some digging and came across a great post on the Microsoft newsgroups and found the solution. I just implemented it and it works flawlessly.
No more having to go into display settings and adjust my resolution and primary monitor each time I unlock or reboot my system.
Fix Action (Disable Transient Multi-Monitor Manager Task):
– Right click on My computer -> Select Manage
– Double Click Task Scheduler
-> Task Scheduler Library
– Highlight TMM in the center pane
– End & Disable the task via the action pane on the right
– Issue Solved
