I had the same problem. I dont know why we are the only ones, however. I found this worked for me. This is an article in PCmag.

The solution lies in scheduling a task that runs at start-up. You might think Vista would block this too, but there's a reason it doesn't. Any process can tweak the standard start-up locations without triggering UAC, so those locations are considered dangerous. But launching Task Scheduler requires UAC confirmation, and thus Vista trusts scheduled tasks. Here's what you do:
• Click the Start orb and enter Task Scheduler.
• Enter an Administrator password or click Confirm as required by UAC.
• Click the Create Task link (not Create Basic Task).
• On the general tab name the task Startup Cop Pro.
• Select a user account that has Administrator privileges.
• Check the option Run only when user is logged on.
• Check the box Run with highest privileges.
• Click the Triggers tab and click the New button.
• Select At log on from the drop-down list at the top.
• Check the Any user option.
• At the bottom under Advanced Settings, check the Enabled box and click OK.
• Click the Actions tab and click the New button.
• Click Browse and locate the utility.
• In the Add arguments box enter /Startup.
• Click the Settings tab.
• Check the box Run task as soon as possible after a scheduled start is missed.
• Uncheck the box Stop the task if it runs longer than:
• Click OK, OK].
Whew! Now launch Startup Cop Pro, click Settings, and uncheck the Run Startup Cop Pro at startup box. When you reboot, Startup Cop Pro will launch at start-up with no gripes from Vista. Of course, you can apply this technique to any program that's blocked from ordinary start-up by Vista's UAC .
MAKE SURE YOU
DISABLE THE NORMAL AUTOSTART.
I didnt and it cause an error. you can remove the autostart in msconfig or in the regedit.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
remove twonkyvision
If you have found a better way please let me know, I tried everything and this is what worked.
